Introduction

Release 2.5.11 of the Cisco CDS-IS-ISM is the initial release of Internet Streamer (IS) software for the Integrated Services Module (ISM) line card of the Cisco ASR 9000 Series Router. It has feature parity with the standalone CDS-IS 2.5.11 code release, with added support for the ISM line card.

Please refer to the standard CDS-IS 2.5.11 Release Notes for details on the 2.5.11 baseline release.

Cisco IOS XR software is a distributed operating system designed for continuous system operation combined with service flexibility and high performance.

Cisco IOS XR software running on the Cisco ASR 9000 Series Router provides the following features and benefits:

ISM Adds support for ASR9000 ISM line card. This release maintains feature parity with the standalone CDS-IS 2.5.11 code release, but is designed to run on the ASR9000 ISM line card.

IRB over CDS-IS Cisco IOS XR Software Release 4.2.1 introduces support for Integrated Routing and Bridging (IRB) on the ISM line card running the Cisco Internet Streamer Content Delivery System (CDS-IS).

For more information about the Cisco Internet Streamer Content Delivery System (CDS-IS), refer to the Cisco Internet Streamer CDS 2.5 Software Configuration Guide. For a complete list of Cisco Internet Streamer Content Delivery System Command-Line Processing commands, refer to the Cisco Internet Streamer CDS 2.5 Command Reference Guide.

System Requirements

This section describes the system requirements for Cisco ASR 9000 Series Router Software Release 4.2.1. The system requirements include the following:

Cisco ASR 9000 Series Router ISM line card must be physically present in the router

Cisco ASR 9000 Series Router must be running Cisco IOS XR software Release 4.2.1 or greater

Limitations

This release contains the following limitations and restrictions:

SAM Online Insertion and Removal

On a CDS-IS appliance, CDNFS drives can be removed and replaced while the system is running, however it is currently a limitation of the CDS-IS application that one of the CDNFS drives may not be removed. This one drive stores key metadata that is required to service client requests. This same restriction applies to the ISM platform. The ISM platform groups the CDNFS drives into two modules and all drives on that module must be removed at the same time. As a result, the chances of attempting to remove a key metadata are quite high. To provide consistency between the two SAM modules, no OIR is supported for CDS-IS on the ISM platform.

The SAM attention button is non-functional for the ISM-IS application. Similarly, any Cisco IOS XR software command line interface commands to stop or remove the SAM are not supported. The SAM modules should not be physically removed while the CDS-IS application is running or data corruption may occur.

Port Channel Configuration is Not Supported

ISM is a line card plugged into the Cisco ASR 9000 Series Router. All ISM interfaces are internal to the router, and there are no external interfaces. Therefore it will not be the case that the network cable is unplugged. It is not beneficial to support the port channel configuration to provide the physical link redundancy.

Maximum Bandwidth Change in CLI not in CDSM

ISM can be configured with a maximum of four streaming interfaces, and each interface can provide up to 10G bandwidth. The maximum bandwidth for WMT, Movie-Streamer, and FMS was increased to 40G on command line interface configuration. CDSM however is not changed to reflect this maximum allowed bandwidth. The maximum allowed bandwidth on CDSM for the ISM is same as the CDS-IS appliance, which is 8000000 for FMS and 2147483647 for WMT and Movie-Streamer.

Service-Engine Interface Limitations

ACL-based-routing on service-engine interfaces connecting to an ISM (Integrated Service Module) line card is not supported in Cisco IOS XR Release 4.2.1.

Virtual Routing and Forwarding (VRF) on service-engine interfaces connecting to an ISM (Integrated Service Module) line card is not supported in Cisco IOS XR Release 4.2.1.

Important Notes

Static Route Configuration for the Service-Management Interfaces

There are two types of interfaces on CDS- IS-ISM: the service-management interfaces which are used for low-bandwidth management traffic, and the service-engine interfaces which are used for high-bandwidth streaming and cache-fill traffic. From the Cisco IOS XR software command line interface, users can configure default gateways for both interface types, however CDS-IS-ISM ignores any default gateway configuration for service-management interfaces. This is required to avoid sending streaming traffic to management destinations, since, if there are multiple default gateways, CDS-IS-ISM uses equal-cost multipath routing to direct traffic across all default gateways equally. For management traffic, users should add static routes to the service-management interfaces from the CDS-IS command line interface for routing purposes. The static routes can be added either using the setup utility or the ip route command in global configuration mode.

Device Activation Change for ISM on CDSM

On a CDSM's device activation page, the "Use SE's primary IP Address for Management Communication" check box is checked by default. For the ISM platform, the primary interface is a Service-Engine interface and should not be used for Management Communication. Rather, a separate Management specific (Service-Management) interface should be used. To use a Service-Management interface for Management Communication, do the following:


Step 1 Uncheck the "Use SE's Primary IP Address for Management Communication" check box.

Step 2 Fill in the Service-Management IP Address in the "Management Communication Address" text box.

Step 3 Fill in port number 443 in the "Management Communication Port" text box.


Default Interface MTU Value Displayed in CLI

The default interface MTU value for a CDS-IS appliance is 1500, and this value is not displayed in the show running-config CLI command. The default MTU value for CDS-IS on ISM interfaces is 9000, and it is explicitly shown in the show running-config CLI command. This default value is displayed on ISM so that the customers are aware of the different MTU values (between a CDS-IS appliance and CDS-IS on ISM). The MTU value is configured from the Cisco IOS XR software command line interface. The CDS-IS application enforces a minimum MTU of 576, and will set this MTU size if the value configured from XR is less than 576.

Caveats

Caveats describe unexpected behavior in CDS-IS-ISM software releases. Severity-1 caveats are the most serious caveats; severity-2 caveats are less serious.

This section lists the ISM-specific caveats for the CDS-IS-ISM Software Release 2.5.11 for Integrated Services Module (ISM) line cards and hardware caveats for the ISM line card residing in the Cisco ASR 9000 Series platform.

Open Caveats

The open caveats listed here are specific to the ISM line card. Please refer to the standard CDS-IS 2.5.11 Release Notes for details on the 2.5.11 baseline open caveats.

CSCts16030

Basic Description:

On CDS-IS-ISM bootup, a CDNFS drive is reformatted if a corrupt partition table is detected. Content on that drive is lost.

Symptom:

On CDS-IS on ISM bootup, a CDNFS drive is reformatted and content on that drive is lost.

Conditions:

This occurs when a corrupt partition table is detected when reloading a CDS-IS on ISM blade.

Workaround:

No available workaround is known at this time.

CSCtt27512

Basic Description:

On CDS-IS-ISM bootup, error messages indicate problem adding drive to CDN, until retry mechanism completes. Error messages then stop after a few seconds.

Symptom:

On CDS-IS ISM bootup, error messages indicate problem adding drive to CDN, until retry mechanism completes. Error messages then stop after a few seconds.

Conditions:

This occurs randomly when booting the CDS-IS ISM blade.

Workaround:

No workaround is needed.

Resolved Caveats

The resolved caveats listed here are specific to the ISM line card. Please refer to the standard CDS-IS 2.5.11 Release Notes for details on the 2.5.11 baseline resolved caveats.

CSCts34309

Basic Description:

Statistics shown for the Service Engine interface and the I/O interface commands (from IOS-XR command line) do not match corresponding statistics on the ISM itself. The ISM side linux statistics are accurate.

Symptom:

The counters may not match b/w the I/O interface and the AVSM interfaces when traffic is flowing.

Conditions:

Http traffic flowing through the setup

Workaround:

There is no workaround.

Installation/Upgrading to Release 2.5.11

As this is the initial release of the ISM software, there is no upgrade path. A clean install must be performed to initially load the CDS-IS-ISM software onto an ISM line card, as outlined below:

Prerequisites:

The Cisco ASR 9000 Series Router is installed with the correct Cisco IOS XR software Release 4.1.2 image

All the ISM interfaces are configured in Cisco IOS XR software, and the SAM modules on the ISM line card are functional

Installation Instructions:


Step 1 Follow the steps below to boot to the Linux rescue image:

Steps:

a. TFTP the rescue image to /disk0: in your router, using the command "copy tftp: /disk0:"

RP/0/RSP0/CPU0:asr9k-14#copy tftp: disk0:
 
   

The following displays:

Thu Mar 24 15:43:22.762 UTC
Address or name of remote host []?1.2.3.4
Source filename [/tftp:]? sim100_x86_64_rescue.bzImage
Destination filename [/disk0:/sim100_x86_64_rescue.bzImage]?
Accessing tftp://13.2.13.2/sim100_x86_64_rescue.bzImage
CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC
 
   

Where "Address of the remote host" is the address of the FTP Server on which the Linux rescue image resides.

b. Attach to the PPC(CPU0) console from the Cisco IOS XR software command line interface by entering the following command:

 RP/0/RSP0/CPU0:asr9k-14# run attachCon 0/<slot>/CPU<#> 9600
 
   

You can detach from the console and return to the Cisco IOS XR software command line interface by entering the detach command at the PPC(CPU0) console prompt.

c. Boot the ISM to the rescue Linux image, using the avsm_se_cmd boot maint_image /disk0:/sim100_x86_64_rescue.bzImage command from the PPC console

#avsm_se_cmd  boot maint_image /disk0:/sim100_x86_64_rescue.bzImage
 
   

Step 2 Once the ISM boots into the rescue image, attach to the x86 console and use scp to transfer the CDS-IS ISM image (cds_is_25-ism-install.sh) from the location/Server where it was downloaded.

Steps:

a. Attach to the x86 console from the Cisco IOS XR software command line interface by entering the following command:

RP/0/RSP0/CPU0:asr9k-14# run attachCon 0/4/CPU1 115200
 
   

You can detach from the console and return to the Cisco IOS XR software command line interface by entering the detach command at the x86 console prompt.

b. Use scp to transfer the CDS-IS image to the ISM line card. Using scp requires that you have configured networking for at least one interface.

[root@sim100-rescue-linux tmp]# scp root@1.2.3.4:/tmp/cds_is_25-ism-install.sh ./
 
   

c. Set the cds_is_25-ism-install.sh file permissions to executable using the chmod +x <filename> command:

[root@sim100-rescue-linux tmp]# chmod +x cds_is_25-ism-install.sh
 
   

d. Execute the following command to run the installer:

[root@sim100-rescue-linux tmp]# ./cds_is_25-ism-install.sh
 
   

Step 3 Reboot the ISM line card to load the new image

a. Using the Cisco IOS XR software command line interface, execute the command hw-module location 0/<slot#>/CPU0 reload

RP/0/RSP0/CPU0:asr9k-14#hw-module location 0/4/CPU0 reload
Thu Mar 24 15:58:53.084 UTC
WARNING: This will take the requested node out of service.
Do you wish to continue?[confirm(y/n)]y
 
   

When the system boots up after a reload, the ISM line card is installed with the new image and the login prompt is displayed to the user

b. Login as admin and enter the password default to login to the ISM line card

Step 4 Execute the show version command to display the version of software installed on the ISM line card:

a. Establish a Telnet session with the router.

b. Enter the show version command:

RP/0/RSP0/CPU0:router#show version

Upgrading Cisco IOS XR Software

Cisco IOS XR software is installed and activated from modular packages, allowing specific features or software patches to be installed, upgraded, or downgraded without affecting unrelated processes. Software packages can be upgraded or downgraded on all supported card types, or on a single card (node).

Software packages are installed from package installation envelope (PIE) files that contain one or more software components. Refer to Table 1 in the Release Notes for Cisco ASR 9000 Series Aggregation Services Routers for Cisco IOS XR Software Release 4.1.2 online for a list of the Cisco ASR 9000 Series Router software feature set matrix (PIE files) and associated filenames available for the Cisco IOS XR Software Release 4.1.2 supported on the Cisco ASR 9000 Series Router.
