Graceful insertion of VSM card on ASR9000 routers

Part-A: VSM card readiness

1. Pre-Installation Information
   1. VSM-500 card supported on ASR9904,ASR9006,ASR9010,ASR9912,ASR9922 chassis
   2. This card supported from IOS-XR 5.1.1 release
   3. VSM-500 is supported with RSP440 / RP2/RSP880
   4. VSM-500 supports CGN and TMS-Arbor services

2. Prerequisites files for VSM operations are :

VSM Services Infra Pie	asr9k-services-infra.pie
CGv6 Services pie	asr9k-services-px.pie
FPD PIE	asr9k-fpd-px.pie
VSM OVA Package	asr9k-vsm-cgv6-<version>.ova
Mandatory SMU(s) for target release	asr9k-CSCxxxxx-px.pie

Part-B: installation with service configuration

1. Make sure all above mentioned PIEs are installed.

Check with Show install summary

2. Make sure FPD is correctly upgraded

Check with sh hw-module fpd location all

3. Install mandatory SMUs

Note: - To identify the bare minimum mandatory SMUs we need for VSM in key releases using CSM, Please refer below link.

4. Install & activation of CGv6.ova for CGN services:-

1. Once VSM card in IOS-XR RUN state then we need to perform upgrade activity.

Note: - Pre-533 IOS XR code, disabling CoPP TFTP config was required. From IOS-XR 5.3.3 no TFTP config changes required.

1. Installation VSM Ova package with CGv6 config: -

Step 1: Copy cgn.ova file to RSP (E.g. to disk0:)

Step 2: Enable virtual service.

RP/0/RSP0/CPU0:Esc_CGN(config)#virtual-service enable

RP/0/RSP0/CPU0:Esc_CGN(config)#commit

Step 3: Install CGN OVA using CLI from execution mode:

RP/0/RSP0/CPU0:Esc_CGN# virtual-service install name cgn123 package disk0:/asr9k-vsm-cgv6-<version>.ova node 0/1/CPU0

Please note: Installation will take about 6-8 minutes.

Step 4: Check installation progress using show virtual-service list CLI. When the status is shown as "Installed", installation is completed.
