This chapter provides physical and functional overviews of the Cisco 7200 VXR routers. Descriptions and examples of software commands are included when they are necessary for replacing, installing, configuring, or maintaining the router hardware.
The following sections describe router hardware, major components, and functions of hardware-related features:
The Cisco 7200 VXR routers are the newest, multiservice members of the Cisco 7200 series routers. The Cisco 7200 VXR routers include the Cisco 7204VXR (4-slot router) and the Cisco 7206VXR (6-slot router).
The Cisco 7200 VXR routers are designed to support gigabit capabilities and to improve data, voice, and video integration in both service provider and enterprise environments.
The Cisco 7200 VXR routers incorporate an integrated Multiservice Interchange (MIX) capability to support future voice applications. MIX interconnections on the midplane provide the ability to switch DS-0 timeslots between multichannel T1 or E1 interfaces, much like a digital cross-connect or an add-drop multiplexer. This feature enables the Cisco 7200 VXR routers to switch DS-0 voice channels on a T1 or E1 interface from one voice processing port adapter to another voice processing port adapter. It also enables DS-0s to be switched through the Cisco 7200 VXR routers without any processing, a requirement in certain voice configurations.
The Cisco 7200 VXR routers support a high-speed network services engine (NSE) as well as the high-speed network processsing engine, NPE-300, and all other available network processing engines. The NSE-1 is a combination of a high-performance RISC processor and high-performance PXF processor. The PXF processor works with the routing processor to provide accelerated packet switching, as well as accelerated IP Layer 3 feature processing.
The Cisco 7200 VXR routers also support high-speed network processing engines (NPEs) to provide increased routing and process switching performance. The NPE-300 is a high-performance RISC processor---delivering up to 300-Kpps fast switching and 20-Kpps process switching.
The Cisco 7200 VXR routers with the NSE-1 and NPE-300 installed support both 25-MHz and 50-MHz port adapter operation.
 |
Note For port adapter configuration information, refer to the Cisco 7200 Series Port Adapter Configuration Guidelines publication. |
The Cisco 7200 VXR routers accommodate a variety of network interface port adapters and an I/O controller. A Cisco 7200 VXR router equipped with an NSE-1 or NPE-300 can support up to six high-speed port adapters and can also support higher-speed port adapter interfaces including Gigabit Ethernet and OC-12 ATM. The Cisco 7200 VXR routers also contain bays for up to two AC-input or DC-input power supplies.
The port adapters, I/O controller, and power supplies are the same for all Cisco 7200 series routers and are described in the "Field-Replaceable Units" section. The network processing engines and network services engine are router model specific.
The Cisco 7200 VXR routers support the following features:

Note For a chassis footprint, additional dimensions, and clearance requirements for the Cisco 7200 VXR routers, see the "Site Requirement Guidelines" section in ""Preparing for Installation." |
The Cisco 7204VXR supports multiprotocol, multimedia routing and bridging with a wide variety of protocols and port adapter combinations available for Cisco 7200 series routers. In addition, the Cisco 7204VXR midplane provides increased support for multiple high-bandwidth port adapters.
The Cisco 7204VXR has four slots (slot 1 through slot 4) for port adapters, one slot for an input/output (I/O) controller, and one slot for an network processing engine or network services engine. You can place the port adapters in any of the four available slots. (See Figure 1-1.)
|
Note In Figure 1-1, a blank port adapter is installed in slot 3. To ensure adequate airflow across the port adapters, each port adapter slot must be filled with either a port adapter or a blank port adapter. |
The rear of the Cisco 7204VXR router provides access to the network processing engine or network services engine and up to two power supplies. (See Figure 1-2.)
The network processing engine or network services engine has no external connectors or LEDs. There is a handle for removing and installing the network processing engine or network services engine and two captive installation screws for securing it to the chassis.
The Cisco 7204VXR router comes equipped with one 280W AC-input power supply. (A 280W DC-input power supply option is available.) In Figure 1-2, a Cisco 7204VXR router is configured with a single AC-input power supply. (A power supply filler plate is installed over the second power supply bay.) A fully configured Cisco 7204VXR router operates with only one installed power supply; however, a second, optional power supply of the same type provides hot-swappable, load-sharing, redundant power.
|
Note The Cisco 7204VXR does not support a mixture of AC- and DC-input power. |
The power supply has the router's main power switch and either an AC-input power receptacle or a hardwired DC-input power cable (depending on the type of installed power supply).
Adjacent to the power supply bays are two chassis ground receptacles that provide a chassis ground connection for ESD equipment or a two-hole grounding lug. (See Figure 1-2.)
Three internal fans draw cooling air into the chassis and across internal components to maintain an acceptable operating temperature. (See Figure 1-2.) The three fans are enclosed in a tray that is located inside the chassis.
The I/O controller, port adapters, power supplies, and network processing engine or network services engine slide into their respective chassis slots and connect directly to the routers midplane; there are no internal cables to connect. The midplane distributes power from the power supplies to the I/O controller, port adapters, fan tray, and network processing engine or network services engine.
The midplane also senses OIR of the port adapters, bridges the PCI buses from the port adapters to packet memory on the network processing engine or network services engine, arbitrates traffic across the PCI buses, and generates the clock signals for the port adapters on each PCI bus.
The Cisco 7204VXR operates as either a tabletop or a rack-mounted unit. A rack-mount kit is standard equipment included with all Cisco 7200 VXR routers when they are shipped from the factory. The kit provides the hardware needed to mount the router in a standard 19-inch equipment rack or a telco rack. Steps for installing the Cisco 7204VXR router in an equipment rack are the same for all Cisco 7200 VXR routers and are explained in the chapter "Installing a Cisco 7200 VXR Router." If you are not rack-mounting your Cisco 7204VXR, place it on a sturdy tabletop or platform.
A fully configured Cisco 7204VXR, with two installed power supplies and all chassis slots filled, weighs approximately 50 pounds (22.7 kilograms [kg]). For clearance requirements and rack-mount installation considerations, see the section "Site Requirement Guidelines" section, in "Preparing for Installation."
The Cisco 7206VXR supports multiprotocol, multimedia routing and bridging with a wide variety of protocols and port adapter combinations available for 7200 series routers. In addition, the Cisco 7206VXR midplane provides increased support for multiple high-bandwidth port adapters.
|
Note The Cisco 7206VXR is also available as a router shelf in a Cisco AS5800 Universal Access Server. If your Cisco 7206VXR is installed as a router shelf, use this publication in conjunction with the Cisco AS5800 Universal Access Server publications that shipped with the access server. |
The Cisco 7206VXR has six slots (slot 1 through slot 6) for port adapters, one slot for an input/output (I/O) controller, and one slot for a network processing engine or network services engine. You can place the port adapters in any of the six available slots.
The front of the Cisco 7206VXR provides access to the I/O controller and up to six network interface port adapters. (See Figure 1-3.)
|
Note In Figure 1-3, a blank port adapter is installed in slot 5. To ensure adequate airflow across the port adapters, each port adapter slot must be filled with either a port adapter or a blank port adapter. |
The rear of the Cisco 7206VXR router provides access to the network processing engine or network services engine and up to two power supplies. (See Figure 1-4.)
The network processing engine or network services engine has no external connectors or LEDs. There is a handle for removing and installing the network processing engine or network services engine and two captive installation screws for securing it to the chassis.
The Cisco 7206VXR router comes equipped with one 280W AC-input power supply. (A 280W DC-input power supply option is available.) In Figure 1-4, a Cisco 7206VXR router is configured with a single AC-input power supply. (A power supply filler plate is installed over the second power supply bay.) A fully configured Cisco 7206VXR router operates with only one installed power supply; however, a second, optional power supply of the same type provides hot-swappable, load-sharing, redundant power.
|
Note The Cisco 7206VXR does not support a mixture of AC- and DC-input power. |
The power supply has the router's main power switch and either an AC-input power receptacle or a hardwired DC-input power cable (depending on the type of installed power supply).

For clearance requirements and rack-mount installation considerations, see the section "Site Environment" in the chapter "Preparing for Installation."
The Cisco 7200 VXR routers are easy to service; many of their major components are field-replaceable units (FRUs). The following sections describe Cisco 7200 VXR router FRUs:
|
Note Replacement instructions for removing and replacing FRUs are contained in separate documents that accompany each FRU shipped from the factory. For example, if you need to replace an AC power supply in your Cisco 7200 VXR router, refer to the 280-Watt AC-Input Power Supply Replacement Instructions publication. Replacement instructions are also available on the Documentation CD-ROM and on Cisco Connection Online (CCO). |
The network processing engine or network services engine maintains and executes the system management functions for Cisco 7200 series VXR routers. Also, the network processing engine or network services engine shares the system memory and environmental monitoring functions with the I/O controller.
Cisco 7200 VXR routers support five versions of the network processing engine: NPE-150, NPE-175, NPE-200, NPE-225, and NPE-300. These network processing engines have the same functionality; however, their performance differs because of the microprocessor type and the type of memory for packet data (SRAM and DRAM, or SDRAM) that each network processing engine provides.
Cisco 7200 VXR routers also support the NSE-1, which consists of two modular boards: the processor engine board and the network controller board. The NSE-1 Parallel eXpress Forwarding (PXF) processor works with the routing processor to provide accelerated packet switching, as well as accelerated IP Layer 3 feature processing.
|
Note The NPE-100, although still supported, is no longer an orderable product as of May 2000. |
|
Note Detailed instructions for removing and replacing the network processing engines or network services engine are contained in the Network Processing Engine and Network Services Engine Installation and Configuration publication. This document accompanies every network processing engine or network services engine that is shipped from the factory as a FRU. It is also available on the Documentation CD-ROM and on Cisco Connection Online (CCO). |
The network processing engines and network services engine consist of the following components:
The network processing engines and network services engine perform the following system management functions:

The input/output (I/O) controller shares the system memory functions and the environmental monitoring functions for the Cisco 7200 VXR routers with the network processing engine.
|
Note Detailed instructions for removing and replacing the I/O controller are contained in the Input/Output Controller Replacement Instructions document. This document accompanies every I/O controller that is shipped from the factory as a FRU and is also available on the Documentation CD-ROM and on CCO. |
The I/O controller consists of the following components:
|
Note The I/O controller with the product number C7200-I/O-FE-MII= has a single MII Fast Ethernet receptacle only. The product number for the I/O controller with two Fast Ethernet receptacles, C7200-I/O-FE=, does not specify MII because both an MII and an RJ-45 receptacle are included. |
|
Note When you use the I/O controller that is equipped with an MII receptacle and an RJ-45 receptacle (C7200-I/O-FE=), only one receptacle can be configured for use at a time. You can install an I/O controller with or without a Fast Ethernet port in all Cisco 7200 series routers (including the Cisco 7206 and Cisco 7206VXR as router shelves in a Cisco AS5800 Universal Access Server). |
|
Note Some I/O controllers use an SRAM component with an external lithium battery to provide the same functionality as the NVRAM. (See the second illustration in Figure 1-12 and Figure 1-13.) |
|
Note The I/O controller does not support OIR. You must power down your router before removing the I/O controller. |
|
Note Your I/O controller with the Fast Ethernet port that has MII and RJ-45 receptacles (C7200-I/O-FE=) might look like the first illustration in Figure 1-12, or it might look like the second illustration in Figure 1-12. There is no functional difference between these two I/O controllers with the Fast Ethernet port. |
|
Note Your I/O controller without the Fast Ethernet port (C7200-I/O=) might look like the first illustration in Figure 1-13, or it might look like the second illustration in Figure 1-13. There is no functional difference between these two I/O controllers without the Fast Ethernet port. |
Table 1-11 lists the I/O controller memory components.

|
NVRAM | 128 KB | 1 | Nonvolatile EPROM for the system configuration file | U41 |
| 1Some I/O controllers have no Flash SIMM but use a permanently fixed 4-MB Flash chip instead. (See Figure 1-12 and Figure 1-13 for comparison.) 2The NVRAM on some I/O controllers is replaced by a 32-pin nonsocketed SRAM component that is soldered onto the card in socket U14. The SRAM component is made to act like the NVRAM by the addition of some external components, one of which is a button-type lithium battery. |
Depending on whether the Fast Ethernet port is present, up to five LEDs on the I/O controller faceplate indicate system status; two additional LEDs indicate the status of the Flash Disks or Flash memory cards installed in either PC Card slot.
Figure 1-15 shows the LEDs on the I/O controller with the Fast Ethernet port that is equipped with a single MII receptacle.
|
Note Although still supported by Cisco Systems, the I/O controller equipped with the single MII receptacle is no longer an orderable product as of May 1998. |
Figure 1-16 shows the LEDs on the I/O controller with the Fast Ethernet port that is equipped with an MII receptacle and an RJ-45 receptacle. Figure 1-17 shows the LEDs on the I/O controller without the Fast Ethernet port. Table 1-12 lists I/O controller LEDs and their functions. To use the LEDs for troubleshooting the I/O controller, see the section "Identifying Startup Problems" in "Troubleshooting the Installation."
A CPU reset button is located next to the IO power OK LED or the auxiliary port on the I/O controller faceplate. The CPU reset button resets the entire system.
 |
Caution To prevent system errors and problems, use the CPU reset button only at the direction of your service representative. |
|
Note LEDs are either on or off. The LED state (on or off), not the color, determines the status of connection as described in Table 1-12. However, most LEDs are green when on, with the exception of the IO power OK LED, which is orange when in the on state. |
MII EN | Green | Indicates that the Fast Ethernet port's MII receptacle is initialized and enabled by the system, and is configured for operation. This LED comes on after the I/O controller has been enabled and the MII receptacle has been configured as the media type for the Fast Ethernet port (the RJ-45 receptacle is the default media type for the Fast Ethernet port). This LED remains on during normal operation of the router. |
RJ45 EN | Green | Indicates that the Fast Ethernet port's RJ-45 receptacle (the default media type for the Fast Ethernet port) is initialized and enabled by the system. This LED comes on after the I/O controller has been enabled and remains on during normal operation of the router. |
RJ45 LINK | Green | Indicates that the Fast Ethernet port's RJ-45 receptacle has established a valid link with the network. This LED remains off during normal operation of the router unless there is an incoming carrier signal. |
|
Note The I/O controller without the Fast Ethernet port and the I/O controller equipped with a single MII receptacle do not have the MII enabled, RJ-45 enabled, and RJ-45 link LEDs. |
|
Note An MII link LED is not provided on the I/O controller because the LED is provided on external transceivers that are required for connecting to the MII receptacle on the I/O controller. See the "Connecting to the Fast Ethernet Port" section" in the chapter "Installing a Cisco 7200 VXR Router" for Fast Ethernet MII connection requirements. |
Use the show diag slot 0 command to identify the I/O controller (with or without the Fast Ethernet port) installed in your Cisco 7200 VXR router.
|
Note Slot 0 in the Cisco 7200 VXR routers is always reserved for the Fast Ethernet port on the I/O controller---if present. If you have an I/O controller without the Fast Ethernet port installed in your Cisco 7200 VXR router, the system software does not display output for the show diag slot 0 command. |
See the "Chassis Slot and Logical Interface Numbering" section for information about slot numbering and logical interface numbering for the Cisco 7200 VXR routers.
The following sample output from the show diag slot 0 command is from a Cisco 7206VXR that has an installed I/O controller with the Fast Ethernet port equipped with an MII receptacle and RJ-45 receptacle:

The RJ-45 receptacle is the default media type for the I/O controller that is equipped with an MII receptacle and an RJ-45 receptacle. Use the media-type command to change the I/O controller's media type and the show interfaces command to verify the change. The following example configures the MII receptacle as the media type for the I/O controller:
Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# interface fastethernet 0/0 Router(config-if)# media-type miiRouter(config-if)#no shutdown Router(config-if)# exit Router(config)# %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed

Use the media-type 100X command to return the media type to the RJ-45 receptacle.
The default transmission mode for the Fast Ethernet port on the I/O controller is half-duplex. Use the full-duplex command to change the Fast Ethernet port's transmission mode and the show interfaces command to verify the change as follows:
Router# configure terminal Enter configuration commands, one per line. End with CNTL/Z. Router(config)# interface fastethernet 0/0 Router(config-if)# full-duplexRouter(config-if)#no shutdown Router(config-if)# exit Router(config)# %LINEPROTO-5-UPDOWN: Line protocol on Interface FastEthernet0/0, changed

Use the no full-duplex command to return the Fast Ethernet port on the I/O controller to half-duplex transmission mode.
The port adapters and service adapters installed in the Cisco 7200 VXR routers are of the same type as those installed on the second-generation Versatile Interface Processors (VIP2s) in the Cisco 7500 series routers, in Cisco 7000 series routers with the 7000 Series Route Switch Processor (RSP7000) and 7000 series Chassis Interface (RSP7000CI), in the Cisco AS5800 Universal Access Server, and in the Cisco uBR7246 universal broadband router.
|
Note The port adapters installed in the Cisco 7200 VXR routers support OIR. For an explanation of OIR, see the "Online Insertion and Removal" section. |
All port adapters and service adapters connect to two Peripheral Component Interconnect (PCI) buses on the router midplane. The PCI buses provide a path to packet I/O memory and the system (route/switch) processor. The Fast Ethernet port on the I/O controller connects to a third PCI bus for packet routing and switching. The port or service adapters either provide such services as compression or encryption, or they provide network interfaces to connect the router to external networks.
|
Note Detailed instructions for removing, replacing, and configuring the port adapter types supported on the Cisco 7200 VXR routers are contained in the configuration note for the port adapter. For example, if you plan to replace a 4-port Ethernet port adapter in your Cisco 7200 VXR router, refer the configuration note PA-4E Ethernet 10BASE-T Port Adapter Installation and Configuration. This configuration note accompanies every PA-4E port adapter that is shipped from the factory as an installed item in a Cisco 7200 VXR router or as a FRU. The configuration note is also available on the Documentation CD-ROM and on CCO. |
|
Caution To ensure adequate airflow across the router's port adapters, a port adapter or a blank port adapter must be installed in each port adapter slot. |
The Cisco 7200 VXR routers come equipped with one 280W AC-input power supply. (A 280W DC-input power supply is available as an option.) You must order the second power supply separately. A second power supply, although not required, allows load sharing and increased system availability.
|
Note The Cisco 7200 VXR power supplies are the same as in all Cisco 7200 series routers. |
|
Note Detailed instructions for handling and replacing the Cisco 7200 series power supplies are contained in the configuration notes 280-Watt AC-Input Power Supply Replacement Instructions and 280-Watt DC-Input Power Supply Replacement Instructions. These configuration notes accompany every 280W AC-input power supply and every 280W DC-input power supply that is shipped from the factory as a FRU. These configuration notes are also available on the Documentation CD-ROM and on CCO. |
A handle on the AC and DC power supplies provides a grip point for removing and replacing the power supply. (Figure 1-18 shows the faceplate of the AC-input power supply. Figure 1-19 shows the faceplate of the DC-input power supply.) Two captive installation screws secure the power supply to the chassis and seat the power supply in the router midplane. A power OK LED indicates that the power supply is delivering +5 VDC to the router midplane.
The AC-input power supply has a receptacle for an AC-input power cable. A modular power cable connects the AC-input power supply to the site AC power source. A cable-retention clip secures the power cable to the AC-input power supply.
The DC-input power supply has DC-input power leads that are hardwired to a DC-input terminal block. A cable tie is shipped with each DC-input power supply to secure the leads to the power supply faceplate and provide strain relief for the leads.
|
Caution To ensure adequate airflow across the router power supplies, a power supply or a power supply filler plate must be installed in each power supply bay. Figure 1-4 shows a Cisco 7206VXR with an installed power supply filler plate. |
Table 1-1, earlier in this chapter, lists the AC-input and DC-input power supply system power specifications, including input voltage and operating frequency ranges.
|
Note Each AC-input power supply operating at 120 VAC requires a minimum of 5A service. We recommend powering the Cisco 7206VXR from a 15A receptacle at the power source. |
|
Note Each DC-input power supply operating at -48 VDC in North America requires a minimum of 13A service. Each DC-input power supply operating at -60 VDC in the European Community requires a minimum of 8A service. This product relies on the building's installation for short-circuit (overcurrent) protection. Ensure that a listed and certified fuse or circuit breaker, 20A minimum 60 VDC, is used on all current-carrying conductors. |
The power OK LED goes off and the power supply shuts itself down when the internal DC voltages exceed allowable tolerances or the internal temperature of the power supply exceeds allowable tolerances. The power supply remains in a shutdown state until it is disconnected and reconnected to the source power, and then restarted with the power switch. The power switch turns the power supply on and starts the system. For a description of power-supply shutdown conditions and thresholds, see the "Environmental Monitoring and Reporting Functions" section.
The Cisco 7200 VXR chassis, shown in Figure 1-20, has four or six slots for the port adapters (depending on your chassis model), one slot for the I/O controller, and one bay for the subchassis. The subchassis assembly contains the midplane, the fan tray, two power supply bays, and one slot for the network processing engine. The replacement chassis includes the subchassis assembly and one power supply.
|
Note To replace the chassis, you must remove and replace all the port adapters, the I/O controller, and the network processing engine; therefore, when replacing the chassis, refer to the configuration notes that explain how to remove and replace these units. These configuration notes accompany every chassis that is shipped from the factory as a FRU. The configuration notes are also available on the Documentation CD-ROM and on CCO. |
The Cisco 7206VXR supports up to two installed Flash Disks or two Flash memory cards.
|
Note To avoid potential problems when you install spare Flash Disks or memory cards in your Cisco 7206VXR, we recommend that you reformat all your Flash Disks or memory cards on a Cisco 7206VXR that is running the Cisco IOS Release recommended for your system (see Table 1-1) during your regularly scheduled service times. The document Memory Replacement Instructions for the Network Processing Engine and the Input/Output Controller that shipped with your system explains how to reformat a Flash memory card. |
With Flash memory (Flash Disks or Flash memory cards and the Flash SIMM on the I/O controller) you can remotely load and store multiple system and boot helper images. You can download a new image over the network, and then add the new image to Flash memory or replace existing files. You can also transfer images between Flash Disks or Flash memory cards and the onboard Flash memory SIMM. You can then boot the router either manually or automatically from any of the stored images. Flash memory can also function as a TFTP server to allow other routers to boot remotely from stored images or copy them into their own Flash memory.
|
Note For procedures that explain the use of the Flash Disk, refer to the Using the Flash Disk document that accompanies every Flash Disk shipped from the factory. For procedures that explain how to replace the main, Flash, and ROM monitor memory, refer to the Memory Replacement Instructions for the Network Processing Engine and the Input/Output Controller document that shipped with your system. Documents are also available on the Documentation CD-ROM and on CCO. |
Table 1-13 lists the factory-installed Flash memory card options and their product numbers, and Table 1-14 lists the Flash Disk memory options and their product numbers.

For detailed instructions about how to install the rack-mount and cable-management brackets on your Cisco 7200 VXR router, see the sections "Rack-Mounting a Cisco 7200 VXR Router" and "General Tabletop or Workbench Installation" in the chapter "Installing a Cisco 7200 VXR Router."
This section provides a functional overview of the Cisco 7200 VXR routers. It describes the numbering and addressing scheme of the port adapters for the router, the environmental monitoring and reporting functions, and online insertion and removal (OIR). These descriptions help you become familiar with the capabilities of the Cisco 7200 VXR routers.
In the Cisco 7200 VXR routers, the port-adapter-slot-number is the chassis slot in which a port adapter is installed, whereas the logical-interface-number is the physical location of the interface port on a port adapter.
Port adapter slots in the Cisco 7200 VXR routers are numbered from left to right--- slot 1 through slot 4 in the Cisco 7204VXR (see Figure 1-21) and slot 1 through slot 6 in the Cisco 7206VXR (see Figure 1-22). Port adapter slot 0 is always reserved for the Fast Ethernet port on the I/O controller---if present.
The Media Access Control (MAC)-layer or hardware address is a standardized data link layer address that is required for certain network interface types. These addresses are not used by other devices in the network; they are specific and unique to each port. The Cisco 7200 VXR routers use a specific method to assign and control the MAC-layer addresses of its port adapters. For a description of the MAC-layer address, see the "MAC-Layer Address" section.
Port adapter slots maintain the same slot number regardless of whether other port adapters are installed or removed. However, when you move a port adapter to a different slot, the port adapter slot number changes to reflect the new slot number.
You can identify port adapter slots by using software commands. To display information about all port adapter slots, use the show interfaces command. To display information about a specific port adapter slot, use the show interfaces command with the port adapter type and slot number in the format show interfaces port-adapter-type slot-number/port-number. If you abbreviate the command (sh int) and do not specify port adapter type and slot number (or arguments), the system interprets the command as show interfaces and displays the status of all port adapters and ports.
The following example shows how the show interfaces command, used without arguments, displays status information (including the physical port adapter number) for each port adapter in a Cisco 7206VXR.
In the following example, most of the status information for each interface is omitted.
Router# show interfaces FastEthernet0/0 is administratively up, line protocol is up Hardware is DEC21140, address is 0000.0000.0000 (bia 0000.0000.0000) Internet address is 1.1.1.3
MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, rely 255/255, load 1/255
( display text omitted) Ethernet1/0 is administratively down, line protocol is down Hardware is MIF68840_MM, address is 0000.0000.0000 (bia 0000.0000.0000)
Internet address is 1.1.1.0 MTU 4470 bytes, BW 100000 Kbit, DLY 100 usec, rely 255/255, load 1/255 ( display text omitted) Serial2/0 is administratively up, line protocol is up
Hardware is AmdP2, address is 0000.0000.0000 (bia 0000.0000.0000) Internet address is 1.1.1.7 MTU 1500 bytes, BW 100000 Kbit, DLY 1000 usec, rely 255/255, load 1/255
( display text omitted)
You can also use arguments such as the interface type (Ethernet, Token Ring, ATM, and so forth) and the port address (slot-number/port-number) to display information about a specific interface only.
The following example shows the display for the first port on the Fast Ethernet port adapter in port adapter slot 3:
Router# show interface fastethernet 3/0 FastEthernet3/0 is up, line protocol is up Hardware is DEC21140, address is 0000.0000.0000 (bia 0000.0000.0000) Internet address is 1.1.1.8 MTU 1500 bytes, BW 100000 Kbit, DLY 100 usec, rely 255/255, load 1/255 Encapsulation ARPA, loopback not set, keepalive not set Full-duplex, 100Mb/s, 100BaseTX/FX ARP type: ARPA, ARP Timeout 04:00:00 display text omitted
For complete descriptions and instructions of the commands used to configure your Cisco 7200 VXR router, refer to the Configuration Fundamentals Configuration Guide and Configuration Fundamentals Command Reference publications, which are available on the Documentation CD-ROM or in print.
All LAN interfaces (ports) require unique MAC-layer addresses, also known as hardware addresses. Typically, the MAC address of an interface is stored on a memory component that resides directly on the interface circuitry; however, the OIR feature requires a different method. (For a description of OIR, see the "Online Insertion and Removal" section.)
Using the OIR you can remove a port adapter and replace it with another identically configured one. If the new port adapter matches the port adapter you removed, the system immediately brings it on line. In order to enable OIR, an address allocator with unique MAC addresses is stored in an EEPROM on the router midplane. Each address is reserved for a specific port and slot in the router regardless of whether a port adapter resides in that slot. The MAC addresses are assigned to the slots in sequence. The first address is assigned to slot 0, and the last address is assigned to slot 4 in the Cisco 7204VXR or to slot 6 in the Cisco 7206VXR. Using this address scheme, you can remove port adapters and insert them into other routers without causing the MAC addresses to move around the network or be assigned to multiple devices.
Note that if the MAC addresses were stored on each port adapter, OIR would not function because you could never replace one port adapter with an identical one; the MAC addresses would always be different. Also, each time a port adapter was replaced, other devices on the network would have to update their data structures with the new address. If the other devices did not update quickly enough, the same MAC address could appear in more than one device at the same time.
|
Note Storing the MAC addresses for every slot in one central location means the addresses stay with the memory device on which they are stored. |
All port and service adapters in the Cisco 7200 VXR routers support online insertion and removal (OIR). This function allows you to install and replace port and service adapters while the router is operating; you do not need to notify the software or shut down the system power. This provides a method that is seamless to end users on the network, maintains all routing information, and preserves sessions.
The following is a functional description of OIR for background information only; for specific procedures for installing and replacing a port or service adapter in a Cisco 7200 VXR router, refer to the configuration note that ships with each port or service adapter.
Each port or service adapter has a bus connector that connects it to the router midplane. Each midplane connector has a set of tiered pins in three lengths that send specific signals to the system as they make contact with the port or service adapter. The system assesses the signals it receives and the order in which it receives them to determine if a port or service adapter is being removed or inserted into the midplane. From these signals, the system determines whether to reinitialize a new interface or shut down a removed interface.
For example, when you insert a port or service adapter, the longest pins make contact with the port or service adapter first, and the shortest pins make contact last. The system recognizes the signals and the sequence in which it receives them.
When you remove or insert a port or service adapter in a Cisco 7200 VXR router, the midplane pins send signals to notify the system, which then performs as follows:
1. Rapidly scans the midplane for configuration changes.
2. Initializes all newly inserted port or service adapters, noting any removed interfaces and placing them in the administratively shut down state.
3. Brings all previously configured interfaces on the port adapter back to the state they were in when they were removed. Any newly inserted interfaces are put in the administratively shut down state, as if they were present (but not configured) at boot time. If a similar port adapter type is reinserted into a slot, its ports are configured and brought on line up to the port count of the original port adapter. (A service adapter has no configurable ports.)
Environmental monitoring and reporting functions are controlled by the network processing engine and allow you to maintain normal system operation by identifying and resolving adverse conditions prior to loss of operation. The environmental monitoring functions constantly monitor the internal chassis air temperature and DC supply voltages and currents. Each power supply monitors its own voltage and temperature and shuts itself down if it detects a critical condition within the power supply. If conditions reach shutdown, the system shuts down to avoid equipment damage from excessive heat. The reporting functions periodically log the values of measured parameters so that you can retrieve them for analysis later, and the reporting functions display warnings on the console if any of the monitored parameters exceed defined thresholds.
The environmental monitoring functions use four sensors, two on the network processing engine and two on the I/O controller, to monitor the temperature of the cooling air as it moves through the chassis.
If the air temperature exceeds a defined threshold, the system controller displays warning messages on the console terminal, and if the temperature exceeds the shutdown threshold, the system controller shuts down the system. The system stores the present parameter measurements for both temperature and DC voltage in NVRAM so you can retrieve them later as a report of the last shutdown parameters.
In addition, the power supplies monitor internal power supply temperature and voltages. A power supply is either within tolerance (normal) or out of tolerance (critical). If an internal power supply temperature or voltage reaches a critical level, the power supply shuts down without any interaction with the system processor.
The environmental monitoring functions use the following levels of status conditions to monitor the system:
Table 1-15 lists the typical temperature thresholds for each network processing engine type, and Table 1-16 lists the DC power thresholds for the normal, warning, and critical (power supply-monitored) levels.

The Cisco 7200 VXR routers display warning messages on the console if chassis interface-monitored parameters exceed a desired threshold. You can also retrieve and display environmental status reports with the show environment, show environment all, show environment last, and show environment table commands. Parameters are measured and reporting functions are updated every 60 seconds. A brief description of each of these commands follows.
|
Caution To prevent overheating the chassis, ensure that your system is drawing cool inlet air. Overtemperature conditions can occur if the system is drawing in the exhaust air of other equipment. Ensure adequate clearance around the sides of the chassis so that cooling air can flow through the chassis interior unimpeded and exhaust air exits the chassis and is not drawn into the inlet vent of another device. |
The show environment command displays reports of the current environmental system status. The report displays parameters that are out of the normal values. No parameters are displayed if the system status is normal. The example that follows shows the display for a system in which all monitored parameters are within normal range:
Router# show environment
All measured values are normal
If the environmental status is not normal, the system reports the worst-case status level. Following is a sample overvoltage warning:
Router# show environment
Warning: +3.45 V measured at +3.83 V
Following is sample output of the show environment last command:
NPE300(boot)# show environment last chassis inlet previously measured at 27C/80F chassis outlet 1 previously measured at 30C/86F chassis outlet 2 previously measured at 30C/86F chassis outlet 3 previously measured at 37C/98F +3.45 V previously measured at +3.46 +5.15 V previously measured at +2.57 +12.15 V previously measured at +6.07 -11.95 V previously measured at -5.97 last shutdown reason - power supply shutdown
The show environment table command displays the temperature and voltage thresholds for each temperature sensor and for each monitored status level. These thresholds are related to those listed in Table 1-15 and Table 1-16. The display also lists the shutdown threshold for the system.
Following is sample output of the show environment table command for a Cisco 7206VXR that has an installed NPE-300:
NPE300(boot)# show environment table
Sample Point chassis inlet | LowCritical | LowWarning | HighWarning 40C/104F | HighCritical 50C/122F |
System shutdown for chassis outlet 1 58C/136F System shutdown for chassis outlet 3 65C/149F
|
Note Temperature ranges and values are subject to change. |
The show environment all command displays an extended report that includes temperature readings and voltage readings. The show environment all command also displays a report showing which power supply slots are occupied and which are empty.
Following is sample output of the show environment all command:
NPE300(boot)# show environment all Power Supplies: Power supply 1 is unmeasured. Power supply 2 is unmeasured. Temperature readings: chassis inlet measured at 28C/82F chassis outlet 1 measured at 28C/82F chassis outlet 2 measured at 30C/86F chassis outlet 3 measured at 30C/86F Voltage readings: +3.45 V measured at +3.45 V +5.15 V is unmeasured +12.15 is unmeasured -11.95 is unmeasured Envm stats saved 0 time(s) since reload
When the system power is on, all three fans should be operational. The system continues to operate if a fan fails; however, if the air temperature exceeds a defined threshold, the system controller displays warning messages on the console terminal, and if the temperature exceeds the shutdown threshold, the system controller shuts down the system.
If the system does shut down because the temperature exceeded the shutdown threshold, the system displays the following message on the console screen and in the environment display when the system restarts:
Queued messages: %ENVM-1-SHUTDOWN: Environmental Monitor initiated shutdown
For complete descriptions and instructions for the environmental monitor commands, refer to the Configuration Fundamentals Configuration Guide and Configuration Fundamentals Command Reference publications, which are available on the Documentation CD-ROM or in print.
