New and Changed Information

The following sections list the new hardware and software features supported by the Cisco 6400 NRP for Release 12.1 DC.

New Hardware Features Supported in Release 12.1(1) DC1

There are no new hardware features for the Cisco 6400 UAC supported in 12.1(1) DC1.

New Software Features in Release 12.1(1) DC1

The following new software features are supported by the Cisco 6400 UAC for Cisco IOS Release 12.1(1) DC1.

Cisco Express Forwarding

CEF switching is now supported for PPP over ATM (PPPoA), generic routing encapsulation (GRE), and Network Address Translation (NAT).

Dynamic Host Configuration Protocol Relay for Unnumbered Interfaces Using ATM RBE

Dynamic Host Configuration Protocol (DHCP) Relay now supports unnumbered interfaces using ATM Routed Bridge Encaps (RBE). DHCP Relay automatically adds a static host route specifying the unnumbered interface as the outbound interface.

DHCP Relay can also now use the ip dhcp database  global configuration command. This optional command allows the DHCP Relay to save route information to a TFTP, FTP, or RCP server for recovery after reloads.

For more information on DHCP, see "Configuring DHCP"  in the Cisco IOS IP and IP Routing Configuration Guide  and "DHCP Commands"  in the Cisco IOS IP and IP Routing Command Reference . For more information on the ATM RBE feature, see the ATM Routed Bridge Encaps feature module.

Session Scalability Enhancements

The following enhancements provide better session stability:

For more information, see the Session Scalability Enhancements II  feature module.

L2TP Tunnel Management Enhancements

The L2TP tunnel management enhancements include the following features:

For more information, see the L2TP Tunnel Management Enhancements  feature module.

L2TP Tunnel Service Authorization Enhancements

These enhancements enable the L2TP access concentrator (LAC) to conduct static or dynamic tunnel service authorization. A static domain name can be configured on the ATM PVC port to override the domain name supplied by the client. If a static domain name is not configured, the LAC conducts dynamic tunnel service authorization, which now includes two steps.

    1. Domain Preauthorization—The LAC checks the client-supplied domain name against an authorized list configured on the RADIUS server for each PVC. If successful, the LAC proceeds to tunnel service authorization. If domain preauthorization fails, the LAC attempts PPP authentication/authorization for local termination.

    2. Tunnel Service Authorization—The user profile on the RADIUS server provides a list of domains accessible to the user, enabling tunnel service authorization for the client-supplied domain. If successful, the LAC establishes an L2TP tunnel.

For more information, see the L2TP Tunnel Service Authorization Enhancements  feature module.

L2TP Tunnel Switching

This feature enables the Cisco 6400 NRP to terminate tunnels from LACs and forward the sessions through new L2TP tunnels selected independently of the client-supplied domains. The NRP as a tunnel switch performs VPDN tunnel authorization based on the ingress tunnel names that are mapped to specified LNSes.

For more information, see the L2TP Tunnel Switching  feature module.

Local Forwarding

Local Forwarding enables the Node Route Processor—Service Selection Gateway (NRP-SSG) to forward packets locally.

For more information, see the Node Route Processor —Service Selection Gateway Enhancements III   feature module.

Segmentation and Reassembly Buffer Management Enhancements

This feature includes the following enhancements to segmentation and reassembly (SAR) buffer management:

For more information, see the Segmentation and Reassembly Buffer Management Enhancements   feature module.

PPP Autosense

The PPP Autosense feature enables the network access server (NAS) to:

For more information, see the PPP Autosense  feature module.

PPP over Ethernet Fast Switching for Multicast

PPPoE now supports fast switching for multicast in addition to Cisco Express Forwarding (CEF).

VPI/VCI Identification in RADIUS Requests

This feature enables the RADIUS VC Logging (Cisco IOS Release 12.0(5) DC) feature to support PPPoE. With RADIUS VC Logging enabled, the RADIUS network access server (NAS) port field is extended and modified to carry VPI/VCI information. This information is logged in:

For more information, see the RADIUS VC Logging  feature module.

Software Caveats

Caveats describe unexpected behavior in the Cisco IOS software releases. Severity 1 caveats are the most serious caveats; severity 2 caveats are less serious. This section contains open caveats for the current Cisco 6400 NRP IOS release only. Because Release 12.1(1) DC1 is the initial base release, there are no resolved caveats. For a list of the resolved caveats, see the next maintenance release.

Caveats in Cisco IOS Release 12.1(1) T also apply to Release 12.1(1) DC1. For information on caveats in Cisco IOS Release 12.1(1) T, see Caveats for Cisco IOS Release 12.1 T  located on CCO and the Documentation CD-ROM.

Note   If you have an account with CCO, you can use Bug Navigator II to find caveats of any severity for any release. To reach Bug Navigator II on CCO, click on Technical Assistance Center, then Software Bug Toolkit. Another option is to go to http://www.cisco.com/support/bugtools.

Open Caveats - Release 12.1(1) DC1

This section describes possibly unexpected behavior by Cisco IOS Release 12.1(1) DC1. This section describes severity 1, 2, and selected severity 3 caveats.

  After all NRP-SSG users log off a specific service, the service object is cleared, but the subblock associated with the interface is not reset. As a result, all traffic from the interface is still treated by NRP-SSG as downstream traffic.
  Workaround (do one of the following):
  Changing service binding while using the service might cause an inconsistency in the service binding table and break the NRP-SSG data path forwarding table.
  Workaround: Avoid changing service binding while the service is in use.
  A node route processor (NRP) ATM interface stops sending when there are multiple particles with data-length 0 at the last particle. The only way to exit this situation is to use the shutdown interface configuration command followed by the no shut interface configuration command. There is no workaround.
  Traffic coming from a Fast Ethernet (FE) interface on a node route processor (NRP), with Inter-Switch Link (ISL) encapsulation, forwarded out of an ATM Route Bridge Encapsulation (RBE) interface, might not be fast-switched but process-switched when you use the bridge irb global configuration command on the NRP.
  Workaround: Remove the bridge irb global configuration command from the configuration.
  If atm ilmi-pvc-discovery subinterface is configured on both the ATM 0/0/0 interface and an ATM subinterface, the ATM PVC will not come up after NRP reloads, unless you do a shut/no shut on the ATM 0/0/0 interface.
  Workaround: Avoid using atm ilmi-pvc-discovery on ATM subinterfaces.
  The NRP should use "big" buffers to do IP Multicast packet replication instead of using "very big" buffers when the payload size is 1500 bytes. Since the NRP has a limited number of "very big" buffers, memory allocation failure may be seen if the payload size is 1500 bytes and IP Multicast is enabled.
  Workaround: Increase the number of "very big" buffers.
  When an NRP-SSG subscriber exceeds the maximum number of services determined by the ssg maxservice global configuration command, the Cisco SSD incorrectly displays the following message: "The server returned an invalid or unrecognized response."
  The correct message reads: "You have reached the maximum allowed number of concurrently logged in services for your system, host-ID. Please logoff of at least one service, and try your service logon request again."
  Workaround: Simply click the "Ok" button to recognize the error, and select the service on the viewService frame again. The correct message will appear.
  The NRP-SSG connection traffic counter always reads zero for the input direction. There is no workaround.
  If you turn on traffic shaping on 400 or more PVCs, and heavy traffic causes the PVCs to become congested simultaneously, random PPP sessions might be dropped.
  Workaround (do one of the following):
  The NRP runs out of memory with 2000 NRP-SSG PPPoE sessions using L2TP services. Current testing shows normal system behavior with 1000 NRP-SSG PPPoE sessions and 50 L2TP tunnels.
  The NRP-SSG DNS fault tolerance feature does not work while CEF is enabled. The secondary DNS sever becomes unreachable upon switchover.
  Workaround: Disable CEF.
  Traffic shaping configuration using the "vbr-nrt <pcr> <scr> <input burst>" under VC-class command cannot be removed by entering "no vbr-nrt <pcr> <scr> <input burst>".
  Workaround: Remove the entire VC-class, and re-enter the VC-class configuration without traffic shaping.
  The NRP crashes during reload when both of the following conditions are met:
  By default, IOMEM = 36MB.
  Workaround (use one of the following):
  The execution of the Show ip nat translation verbose may cause the 6400 NRP to reload. Workaround: Set the terminal length to "term len 0" before executing the Show ip nat translation verbose.

Preexisting NRP Hardware Caveats

This section describes possible unexpected behavior by earlier hardware versions of the NRP. To determine your NRP part number (P/N), see the "Determining Your NRP Part Number" section.

  Affected Part Number: 800-03785-03
  Symptom:
While the NSP is in Slot 0A of a single NSP system, the NRPs reset during NSP reloads or resets.
  Workaround:
In a non-redundant system using an NSP of P/N 800-03785-03, place the NSP in Slot 0B.
  Affected Part Numbers:
800-03655-01, 800-03655-02, 800-03655-03, 800-03655-04
  Symptoms:
Regardless of any boot system global configuration command entries in the startup configuration, the NRP boots the first image in Flash after a reset. This problem occurs after one of the following actions:
  Workaround:
To avoid this problem, make sure that the desired image is the first file on the Flash device. Complete the following steps in EXEC mode:
  Recovery:
If you encounter the problem before implementing the workaround, reset the NRP once by using the hw-module slot number reset EXEC command on the NSP. As long as the NSP sends a single reset to the NRP, the NRP does not ignore the boot system global configuration command entries in the startup configuration.
  Affected Part Numbers:
800-03655-04, 800-03655-05, 800-03655-06
  Symptoms:
With or without redundancy configured, an NRP inserted into a live system might reset the NRP in the adjacent slot of the slot pair. NRP slot pairs are slots 1-2, 3-4, 5-6, and 7-8.
  Workaround (use one of the following):
  Affected Part Number: 800-03655-01
  Symptoms:
When the terminal server is configured such that hardware flow control is enabled on the port attached to the NRP console, the NRP console port does not respond.
  Workaround:
Configure your terminal server to disable hardware flow control on the port attached to the NRP console.
  Affected Part Numbers:
800-03655-01, 800-03655-02, 800-03655-03, 800-03655-04, 800-03655-05, 800-03655-06, 800-03655-07, 800-03655-08
  Symptom:
NSP reports unknown cardtype when the chassis is populated primarily with NRPs.
  Workaround (use one of the following):
  When the Service Selection Gateway (SSG) is enabled after an upgrade from Cisco IOS Release 12.0(3) DC or Release 12.0(5) DC to Release 12.0(7) DC or higher, the SSG transparent passthrough feature is no longer supported.
  Workaround: To enable non-SSG connections to pass through the NRP, disable the SSG with the no ssg enable command.

You can access the most current Cisco documentation on the World Wide Web at http://www.cisco.com. Translated documentation can be accessed at http://www.cisco.com/public/countries_languages.shtml.

Documentation CD-ROM

Cisco documentation and additional literature are available in a CD-ROM package, which ships with your product. The Documentation CD-ROM is updated monthly. Therefore, it is probably more current than printed documentation. The CD-ROM package is available as a single unit or as an annual subscription.

Ordering Documentation

Registered CCO users can order the Documentation CD-ROM and other Cisco Product documentation through our online Subscription Services at http://www.cisco.com/cgi-bin/subcat/kaojump.cgi.

Nonregistered CCO users can order documentation through a local account representative by calling Cisco's corporate headquarters (California, USA) at 408 526-4000 or, in North America, call 800 553-NETS (6387).

Obtaining Technical Assistance

Cisco provides Cisco Connection Online (CCO) as a starting point for all technical assistance. Warranty or maintenance contract customers can use the Technical Assistance Center. All customers can submit technical feedback on Cisco documentation using the web, e-mail, a self-addressed stamped response card included in many printed docs, or by sending mail to Cisco.
