The following sections list the new features supported by the Cisco 6400 in Cisco IOS Release 12.0(7)DB.
The Node Switch Processor with Stratum 3/BITS (NSP-S3B) enables the use of the BITS Network Clocking software feature. The NSP-S3B enables the Cisco 6400 to serve as a stratum 3 network clock source for other network devices. When no external clock source is available, the NSP-S3B provides stratum level 3 internal timing on the Cisco 6400. Otherwise the NSP-S3B is identical to the default NSP. For more information about installing the NSP-S3B, see the Cisco 6400 UAC Hardware Installation and Maintenance Guide .
The BITS Network Clocking feature enables the Cisco 6400 to derive network timing from the central office (CO) BITS. This feature requires the NSP with Stratum 3/BITS (NSP-S3B). For more information about this feature, see the BITS Network Clocking feature module.
The NSP can participate in a Multiprotocol Label Switching (MPLS) network as an ATM label switch router (LSR). For more information about MPLS on the Cisco 6400, see the Configuring Multiprotocol Label Switching on the Cisco 6400 UAC configuration note.
Release 12.0(5)DB for the Cisco 6400 NSP includes a number of software enhancements, including hierarchical VP tunnels, frame relay network and service interworking, and network clock distribution protocol. For more information about the ATM capabilities of the Cisco 6400 NSP, refer to the following documents:
The combined network management Ethernet (NME) interface allows the entire Cisco 6400 system, including the NSP and all installed NRPs, to be managed through a single Ethernet interface. The NME interface eliminates the need for Ethernet cables and connections on individual NRPs. For more information about using the combined NME interface, see "Configuring the NSP" and "Configuring the NRP" in the Cisco 6400 UAC Software Configuration Guide .
The OC12 node line card (NLC) supports bandwidth up to 622 Mbps between the Cisco 6400 Universal Access Concentrators and the network backbone. The OC12 NLC is a full-height card that mounts in the chassis on a full-height carrier module. For more information about installing an OC12 NLC, see the Cisco 6400 UAC FRU Installation and Replacement Guide .
The AC power entry module (PEM) provides power conversion directly from the facility VAC input power to the -48VDC used internally in the Cisco 6400 chassis. AC power comes into the AC PEM through a power cord attached to the front faceplate. An additional AC PEM can be used for redundancy. For more information about installing an AC PEM, see the Cisco 6400 UAC Hardware Installation Guide .
There are no new features supported by the Cisco 6400 NSP in Cisco IOS Release 12.0(4)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 .
There are no new features supported by the Cisco 6400 NSP in Cisco IOS Release 12.0(2)DB.
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.
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.
When an ATM cell is received on the NSP, the generic flow control (GFC) field of the ATM cell is passed without modification to the outbound virtual circuit. This is not compliant with the ATM Forum UNI specification, version 3.1, which requires all bits of the GCF field to be reset to zero.
This section describes possible unexpected behavior by earlier hardware versions of the NSP. To determine your NSP part number (P/N) and hardware version, see the "Determining Your NSP Part Number and Hardware Version" section.
| NME Cable Consolidation is Enabled? | System Uses Redundant NSPs? | Likelihood that CSCdm78716 is the Cause of the Problems |
|---|---|---|
No | No | Not possible---no backplane Ethernet traffic to the NSPs |
No | Yes | Possible, but unlikely |
Yes | Yes or No | Likely |
To determine the part number and hardware version of the NSP, use one of the following methods along with Table 3:
