These release notes describe features and caveats for the Cisco 6400 universal access concentrator (UAC) node switch processor (NSP) and its associated node line cards (NLCs) with Cisco IOS Release 12.0(2)DB.
Use these release notes in conjunction with the cross-platform Release Notes for Cisco IOS Release 12.0 T located on Cisco Connection Online (CCO) and the Documentation CD-ROM.
For a list of software caveats that apply to Release 12.0(2)T, refer to the "Caveats" section of this document.
These release notes discuss the following topics:
The Cisco 6400 UAC consists of an Asynchronous Transfer Mode (ATM) switching core and redundant routing engines. The ATM switch, based on Cisco Catalyst® 8500 + per flow queuing (PFQ) technology, provides the necessary ATM switching and traffic management capabilities; the router blades, derived from the Cisco 7200 router, enable the service provider to offer scalable Layer 3 services.
ATM interfaces connect the Cisco 6400 to digital subscriber line access multiplexers (DSLAMs), as well as ATM or packet cores. Because the Cisco 6400 is designed for the central office environment, it includes switch, router, and line-card redundancy, as well as 12-inch Network Equipment Business Systems (NEBS)-compliant packaging.
This section describes the system requirements for Cisco IOS Release 12.0(2)DB and includes the following sections:
Table 1 describes the memory requirements for the Cisco 6400 platform supported by Cisco IOS Release 12.0 DB.
| Feature Set | Image Name | Minimum Required Flash Disk | Required Main Memory | Runs from |
|---|---|---|---|---|
Cisco 6400 | c6400s-wp-mz.120-2.DB | 3.5 MB Flash | 64 MB DRAM | RAM |
To determine the version of Cisco IOS software currently running on the Cisco 6400, log in to the NSP and use the show version EXEC command. The following is sample output from the show version command performed on the Cisco 6400. The version number is indicated on the second line as shown below:
Cisco Internetwork Operating System Software IOS (tm) C6400 Software (C6400S-WP-M), 12.0(2) DB .....
Additional command output lines include more information, such as processor revision numbers, memory amounts, hardware IDs, and partition information.

The following sections list the new features supported by the Cisco 6400 in Cisco IOS Release 12.0(2)DB.
A new DS3 node line card (NLC) has been developed for the Cisco 6400 chassis. The DS3 NLC is a half-height card that mounts in the chassis on a full-height carrier module. Coaxial interface cables are connected to the DS3 using BNC connectors on the back of the Cisco 6400 chassis. For more information about installing a DS3 NLC, see the Cisco 6400 UAC FRU Installation and Replacement guide.
The only new feature supported by the Cisco 6400 in Cisco IOS Release 12.0(2)DB is support for the DS3 NLC. See the "Documentation Updates" section on page 13 for more detailed information about configuring the NLC.
The DS3 NLC provides two 45-Mbps bidirectional ports for connection to network services using coaxial cable.You can install two DS3s in each carrier module, which can then be installed in slot 1 through slot 8 of a Cisco 6400 chassis. Each port has receive and transmit LEDs that provide port status and operation information. Each interface (or port) in the switch is designated by several different types of addresses. The physical interface address is the actual physical location (slot/subslot/port) of the interface connector within the chassis. The system software uses the physical addresses to control activity within the switch and to display status information. These physical slot/subslot/port addresses are not used by other devices in the network; they are specific to the individual switch and its internal components and software.
In the Cisco 6400, port IDs specify the actual physical location of each port on the system. The address is composed of a three-part number in the format slot/subslot/port. The first number identifies the slot in which the card is installed. Card slots are numbered 1 to 8 from left to right. The second number identifies the subslot number. The NLCs are numbered 0 and 1, with 0 being the top NLC facing the front of the system. The third number identifies the physical port number on the module. The port numbers always begin at 0 and are numbered from the top port to the bottom port, facing the back of the switch.
Interface ports maintain the same port ID regardless of whether other cards are installed or removed. However, when you move an NLC to a different slot, the first number in the address changes to reflect the new slot number.
You can identify module ports by physically checking the slot/subslot/port location on the front of the switch. You can also use software commands to display information about a specific interface, or all interfaces, in the system. To display information about every interface, use the show interface command without parameters. To display information about a specific interface, use the show interface command with the interface type and port address in the format show interface atm slot/subslot/port. This command is described in your command reference publication.
Each port on the ATM port adapters can be configured to support the following clocking options:
Traffic pacing allows you to set the aggregate output traffic rate on any port to a rate below the line rate. This feature is useful when communicating with a slow receiver or when connected to public networks with peak-rate tariffs.
The LEDs on the DS3 NLC provide status and operational information about port 0 and port 1 connections. (See Table 3.)
| LED | Status | Condition |
|---|---|---|
FAIL | Steady yellow Off | DS3 NLC has failed. DS3 NLC is operational. |
PORT 0 (top connector)
RX (receive)
STATUS | Off Steady yellow Green Off Steady yellow Green Off | No traffic. Far end alarm. Receive activity. No traffic. Loss of signal. Active (primary). No power. |
PORT 1 (bottom connector)
RX (receive)
STATUS | Off Steady yellow Off Steady yellow Off | No traffic. Far end alarm. No traffic. Loss of signal. No power. |
If Integrated Local Management Interface (ILMI) has been disabled or if the connecting end node does not support ILMI, the following defaults are assigned to all DS3 interfaces:
The following defaults are assigned to all DS3 interfaces:
This section lists features introduced for the Cisco 6400 in Cisco IOS Release 12.0(1)DB. For more information about these features, refer to the Cisco 6400 Software Configuration Guide located on Cisco Connection Online (CCO) and the Documentation CD-ROM.
Resiliency for both the NSP and NRP is based on extended high system availability (EHSA). If the NRP fails, no virtual circuits (VCs) from the NSP must be reconfigured. The NRP blades also support online insertion and removal (OIR). When operating in non-redundant mode, the NRPs appear as separate network management entities, and can be accessed via individual console ports.
SONET APS provides a mechanism to support redundant transmission circuits, such as single-mode fibers, between SONET devices. Automatic switchover from the primary or working circuit to the backup or protection circuit happens when the working circuit fails or degrades.
The Cisco 6400 supports 1+1, linear, unidirectional, non-reverting APS operation on its redundant OC-3/STM-1 ports.
A telco uses system alarms to help monitor equipment and identify the cause of physical system problems within the central office. There are three levels of alarms: minor, major, and critical, and there are many sources of alarm conditions. Temperature thresholds are one source, but alarms can be triggered by card failure, SONET APS failures, NRP failures, and generic alarms.
The Cisco 6400 includes environmental monitoring hardware and a digital thermometer that measures the temperature of the intake air flow and the temperature at the hottest part of the chassis. Temperature thresholds for each alarm type and location are automatically set, based on empirically determined values that vary depending on the number and type of boards inserted in the chassis. In addition to the automatically set thresholds, you can set your own thresholds for minor and major temperature alarms.
The Cisco 6400 supports BellCore standard alarms, and additional commands have been added that allow you to manage the alarms and reset chassis components as needed.
The Cisco 6400 acts as a DHCP client and automatically acquires an IP address, subnet mask, and default route from a DHCP server on the network. This feature allows you to install the Cisco 6400 in the central office using non-technical personnel. The plug-n-play option allows you to configure the Cisco 6400 from a Network Operations Center (NOC), without being physically close to the system.
Web Console is a graphical user interface (GUI) lets you set or change the system configuration and monitor system activity. The Web Console application is accessible from any Web browser on the Telco management network. You can configure basic system parameters, Simple Network Management Protocol (SNMP) management parameters, set up subscribers, and monitor the current status of your chassis LEDs from anywhere on the network with Web Console.
This section contains important information about use of your Cisco 6400 UAC NSP.
For information about how to install the DS3 NLC, refer to the Cisco 6400 FRU Installation and Replacement guide available on CCO.
If you remove an OC-3 line card from a subslot and insert a DS3 line card into the same slot, the Cisco 6400 issues a warning message and refuses to bring the DS3 card online automatically. This is to prevent accidental misconfiguration of a redundant system. You can avoid the warning message if you shut down all interfaces on the NLC or NRP you want to remove before removing the card.
If you are making this card change intentionally, and a warning message is issued, use the following command to clear the warning and enable the system to bring the new line card online:
nsp# clear facility-alarm source cardtype {slot # | subslot #/#}
The following commands are available for the DS3 NLC:
For more information about these commands, see "DS3 NLC Command Reference,".
Run the NSP 12.0(2)DB image with NRP 11.3(5)DB or later images. NRP 11.3(7)DB, the NRP maintenance release available on January 18, 1999 is strongly recommended.
The NSP 12.0(2)DB image runs on all revisions of NSP shipped to any customer to date.
Install all new NSP software images on the PCMCIA disk (disk0:) and on the NSP bootflash. The new Cisco 6400 image includes an HTML tar file with the Web Console pages and the image file.
Save your existing NSP configuration file off-line, for example on a TFTP server, before upgrading to the new image. Be sure to save the configuration that you really want to preserve; either the running configuration or the startup (NVRAM) configuration, whichever contains the most valid information.
For example, use the copy running-configuration tftp://TFTPHOST/path/name command to save the running configuration from your existing NSP onto your TFTP server.
Alternatively, you can copy the configuration onto the PCMCIA disk using the copy running-configuration disk0:my_nsp_config command.
To install the new image files, follow these steps:
| Step | Command | Task |
|---|---|---|
| 1 | copy tftp://TFTPHOST/imagename.html disk0: | Copy the Web Console tar file to the PCMCIA disk. |
| 2 | copy tftp://TFTPHOST/imagename disk0: | Copy the image file to the PCMCIA disk. |
| 3 | format bootflash: | Format the bootflash to ensure that there is enough room for the new image. (Alternatively, you can delete the oldest image and use the squeeze command to be sure that there is enough space on the bootflash for the new image.) |
| 4 | copy disk0:imagename bootflash: | Copy the image file from the PCMCIA disk to bootflash. |
For more information on the command syntax shown in this section, refer to the Cisco IOS 12.0 documentation set available on CCO. For more information on installing Web Console pages, refer to Chapter 3, "Using the Cisco 6400 Web Console Application for System Configuration" in the Cisco 6400 UAC Software Configuration Guide.
The Web Console application is designed to use JavaScript, which is available with both Netscape Navigator and Microsoft Internet Explorer. However, a number of issues are present when using either application. To date, using Netscape Navigator 4.x has resulted in fewer issues than Microsoft Internet Explorer 4.x.
Before using the Web Console application, verify that your browser is set to use at least 4 MB (4096 KB) of cache memory.
The following sections tell how to deal with some of the browser issues affecting each application.
Web Console might not reflect the most current redundancy status and auto synchronization setting because the check box and option buttons are not displayed properly. Therefore, you must verify your configuration by viewing the configuration file.
An empty dialog box might display after you apply new settings in any of the Web Console pages. If an empty dialog box is displayed, click the Internet Explorer Refresh button to view your new settings.
The show interface command on the Status page fails with Internet Explorer. There is no workaround, so this function is not available.
If a blank window is displayed after you resize your Navigator window, click the Reload button to redisplay the page.
Frequent and rapid clicking on the Web Console Status page can cause syntax and LED errors. This problem is eliminated if the browser cache is set to 4096 KB.
On a dual-NSP system, switchovers can occur if verbose debugging commands, such as debug all or debug oir commands, are used. To avoid this situation when using verbose debug commands, execute the redundancy keepalive disable command at the EXEC prompt prior to turning on the debug command. After debugging is disabled, enter the redundancy keepalive enable command to restore normal system operation.
This section contains open and resolved caveats for the current Cisco 6400 NSP IOS release only.
Caveats in Cisco IOS Release 12.0(2) also apply to Release 12.0(2)DB. For information on caveats in the Cisco IOS Release 12.0(2), refer to the "Caveats" sections in the Cross-Platform Release Notes for Cisco IOS Release 12.0 located on CCO and the Documentation CD-ROM. This section contains caveats affecting all maintenance releases.
This section describes possibly unexpected behavior by Release 12.0(2)DB.This section describes severity 1, 2, and selected severity 3 caveats.
All the caveats in this section are resolved in Release 12.0(2)DB. This section describes severity 1, 2, and selected severity 3 caveats.
This section provides the instructions and command reference information needed to configure the DS3 NLC. This information should be used with the Cisco 6400 UAC Software Configuration Guide and Cisco 6400 UAC Command Reference when configuring your Cisco 6400.
This section describes the commands used to configure the DS3 NLC.
To manually change any of the default configuration values, use the following global configuration commands:
| Step | Command | Task |
|---|---|---|
| 1 | network-clock-select {1-4_priority} atm slot/subslot/port | Configure the network-derived clock. |
| 2 | interface atm slot/subslot/port | Select the interface to be configured. |
| 3 | atm uni [side {network | user}] | Configure the ATM UNI interface. |
| 4 | atm maxvpi-bits 0-8 | Modify the maximum VPI bits configuration. |
| 5 | atm maxvci-bits 0-14 | Modify the maximum VCI bits configuration. |
| 6 | framing {cbitadm | cbitplcp | m23adm | m23plcp} | Modify the framing mode. |
| 7 | scrambling {cell-payload | sts-stream} | Modify the scrambling mode. |
| 8 | clock source {free-running | loop-timed | network-derived} | Modify the clock source. |
| 9 | lbo {long | short} | Modify the line build-out. |
| 10 | auto-ferf {ais | lcd | los | oof | red} | Modify the auto-ferf configuration. |
The following example shows how to change the default ATM interface type to private using the atm uni type private command. Enter configuration commands, one per line. Enter Cntl/z when finished.
6400# config term 6400(config)# interface atm 0/0/0 6400(config-if)# atm uni type private
The following example shows how to change the clock source using the clock source network-derived command. Enter configuration commands, one per line. Enter Cntl/z when finished.
6400# config term 6400(config)# interface atm 0/0/0 6400(config-if)# clock source network-derived
The following four commands used with the DS3 NLC are not documented in the Cisco 6400 UAC Command Reference. Use this information along with the command reference guide to configure your NLCs.
To allow an automatic FERF to be inserted when an incoming alarm is received, use the auto-ferf interface configuration command. To cancel automatic FERF insertion, use the no form of this command.
auto-ferf {los | oof | red | ais | lcd}
los | Loss of signal. |
oof | Out of frame. |
red | Indicates a major alarm. Does not apply to the DS3 NLC. |
ais | Alarm indication signalling. |
lcd | Loss of cell delineation. |
auto-ferf los
auto-ferf oof
auto-ferf red
auto-ferf ais
auto-ferf lcd (applies to non-plcp mode only)
Interface configuration
This command applies to the DS3 interfaces only.
To select a transmit clock source for a physical device such as a port, use the clock source interface configuration command. To return the clock source to the default, use the no form of this command.
clock source {free-running | loop-timed | network-derived}
free-running | The transmit clock is derived from the NSP. |
loop-timed | The transmit clock is derived from the receive (rx) clock. |
network-derived | The transmit clock is derived from the port system clock specified at highest priority when you use the network-clock-select global configuration command. |
loop-timed
Interface configuration
This subcommand allows selection of the transmit clock source for a port's physical device. When a transmit clock port is set to free-running, the port uses the NSP oscillator for clocking.
The following example shows how to enable the loop-timed clocking mode.
Switch(config-if)# clock source loop-timed
framing (interface configuration)
network-clock-select
To select the frame type for the data line, use the framing controller interface configuration command.
framing {m23adm | m23plcp | cbitadm | cbitplcp}
m23adm | The framing mode is M23 ADM. |
m23plcp | The framing mode is M23 PLCP. |
cbitadm | The framing mode is C-Bit ADM. |
cbitplcp | The framing mode is C-Bit PLCP. |
DS3 default is cbitplcp.
Interface configuration
In the DS3 environment, this subcommand allows selection of DS3 framing mode to M23 ADM, M23 PLCP, C-Bit ADM, or C-Bit PLCP.
The following example selects m23adm as the frame type:
Switch(config-if)# framing m23adm
show controllers
To set the line build out to various lengths, use the lbo interface configuration command.
For the DS3 NLC, the syntax is:
lbo {short | long}
short | Sets the line build out up to 255 feet. |
long | Sets the line build out to more than 255 feet. |
The default is short.
Interface configuration
The lbo command applies on DS3 interfaces only.
The following example illustrates how to set the line build out to more than 255 feet for a DS3 NLC:
Switch(config-if)# lbo long
