Upgrading the Cisco VSG and the Cisco Prime NSC

This chapter contains the following sections:

Complete Upgrade Procedure

Table 1 Refer to the Section in Table Based on your Pre-upgrade Product Release
You are Upgrading From Follow The Sequential Steps in the Following Section:

Cisco VSG Release 5.2(1)VSG1(4.1) to Release 5.2(1)VSG2(1.1a) and Cisco VNMC Release 2.1 to Cisco Prime NSC Release 3.2

Upgrade Procedures for Cisco VSG Release 5.2(1)VSG1(4.1) to Release 5.2(1)VSG2(1.1a) and Cisco VNMC 2.1 to Cisco Prime NSC Release 3.2.

This includes upgrade procedures for Cisco Nexus 1000V Release 5.2(1)SM1(5.1) to Release 5.2(1)SM1(5.2).

To upgrade the Cisco Prime NSC, Cisco VSG, and Cisco Nexus 1000V, follow the steps sequentially:
  1. Stage 1: Upgrading Cisco Prime NSC
  2. Stage 2: Upgrading a Cisco VSG Pair
  3. Stage 3: Upgrading the VSM pair and the VEMs

Note

We highly recommend that you upgrade the Cisco VSG and the Cisco Prime NSC in the sequence listed. Any deviation from the ordered steps could cause disruption of your connectivity and data communication. The Cisco Prime NSC must be upgraded with the corresponding policy agent (PA).

Information About Cisco Prime NSC Upgrades

When you upgrade the Cisco Prime NSC software, all current (command-line interface) CLI and (graphical user interface) GUI sessions are interrupted, which means that you must restart any CLI or GUI sessions.

Information About Cisco VSG Upgrades

The upgrade procedure for a standalone Cisco VSG is hitful, which means that you must manually reload the Cisco VSG for the new image to become effective. In HA mode, the upgrade is hitless, which means that the standby Cisco VSG is upgraded first and then after a switchover, the previously active Cisco VSG is upgraded.

Because license information is not stored with the Cisco VSG but is maintained between the Virtual Supervisor Module (VSM) and Virtual Ethernet Module (VEM), if packets are received at the Cisco VSG, that means that the license is valid and the packets are processed.

An upgrade affects two bin files: the kickstart file and the system file.

An upgrade does not erase any of the existing information, when the Cisco VSG comes online. Because the Cisco VSG is stateless, it gets all this information from the Cisco Prime NSC at bootup.

Upgrade Guidelines and Limitations

Before upgrading the Cisco Prime NSC, Cisco VSG, and Cisco Nexus 1000V, read the following:
  • We highly recommend that you upgrade the Cisco VSG and the Cisco Prime NSC in the order provided. Any deviation from the ordered steps could cause disruption of your connectivity and data communication. The Cisco Prime NSC must be upgraded with the corresponding policy agent (PA).
  • Before upgrading to a new VSG version with VSG Universal License (UL), make sure that you change VSM mode to advanced and save the configuration. Installing VSG with UL without changing the VSM mode to advanced may cause VSG service failure.
  • We recommend that you take a snapshot or backup (clone) of the original Cisco Prime NSC and VSM prior to the upgrade process and then perform an ISSU upgrade process on both the VSM and the Cisco VSG. We do not recommend that you perform a manual upgrade.
  • For a full In-service Software Upgrade (ISSU) upgrade on both the Cisco VSG and VSM, follow these rules:
    • Install the Cisco Prime NSC before installing the Cisco VSG and VSM. The ISSU upgrade installs a new PA.
    • A new PA with an old Cisco Prime NSC is not supported and there should never be an interim stage in this state.
    • A copy run start is not required after the VSM upgrade.
  • Upgrade instructions include the following information:
    • Different stages of complete upgrade procedures and operations which are supported at different stages.
    • Different component versions after each stage.
    • Different operations supported after each stage.

      Upgrading Cisco VSG from Release 5.2(1)VSG1(4.1) to 5.2(1)VSG2(1.1a)

      This section includes the following topics:
      Before You Begin
      • You are logged in to the CLI in EXEC mode.
      • You have closed all the active VSG configuration sessions before upgrading the Cisco VSG software.
      • You have copied the kickstart and system images from the remote server to the Cisco Nexus 1000V.

      Cisco VSG Software Upgrade Guidelines

      Follow these VSG upgrade guidelines while upgrading the VSG:

      • Schedule the upgrade when the network is stable. Ensure that nobody is configuring the switch during the upgrade.
      • Ensure that sufficient space is available for copying the upgrade images. A minimum of 200 MB of free bootflash space is required on both the active and standby VSGs.
      • Avoid power interruptions to the hosts running the VSG VMs during any installation procedure.
      • Ensure that the management (mgmt0) interface of the VSG is working and accessible.
      • Ensure that the specified system and kickstart images are compatible with each other.
      • Verify connectivity to the remote server by using the ping command.

      Upgrade a VSG Pair in HA Mode

      You can upgrade VSG pair in the High Availability (HA) mode.

      SUMMARY STEPS

        1.    Log in to the active VSG.

        2.    Display the current boot variables.

        3.    Verify that required space is available to copy the image files. Delete unnecessary files if required to create more space available for copying the new VSG image.

        4.    Verify that required space is available on the standby VSG. Delete unnecessary files if required to create more space available for copying the new VSG image.

        5.    Copy the Cisco Nexus 1000V kickstart and system software files to a server.

        6.    Remove current boot variables.

        7.    Display the current boot variables.

        8.    Load the new boot variables and copy the running configuration to the startup configuration.

        9.    Display the current boot variables.

        10.    Manually reboot the system.

        11.    After the installation operation completes, log in and verify that the switch is running the upgraded software version.

        Upgrading a Device for Standalone VSG

        SUMMARY STEPS

          1.    Log in to the active VSG.

          2.    Use the show boot command to display the current boot variables.

          3.    Verify that required space is available to copy the image files. Delete unnecessary files if required to create more space available for copying the new VSG image.

          4.    Copy the Cisco Nexus 1000V kickstart and system software files to a server.

          5.    Remove current boot variables.

          6.    Display the current boot variables.

          7.    Load the new boot variables and copy the running configuration to the startup configuration.

          8.    Display the current boot variables.

          9.    Manually reboot the system.

          Re-registering the Policy Agent with the Upgraded VSG

          You need to re-register the policy agent after upgrading the Cisco VSG.

          SUMMARY STEPS

            1.    Log in to the active VSG.

            2.    Check the current policy agent version.

            3.    Enter the configuration mode.

            4.    Unregister the old policy agent from VSG.

            5.    Register the new policy agent with the VSG.

            6.    Copy the current running configuration to the startup configuration.

            7.    Verify the updated policy agent version.


          DETAILED STEPS
            Step 1   Log in to the active VSG.
            Step 2   Check the current policy agent version. 
            vsg# show nsc-pa status
NSC Policy-Agent status is - Installed Successfully. Version 2.1(1a)-vsg
VSG#
            Step 3   Enter the configuration mode. 
            vsg# configure terminal
Enter configuration commands, one per line.  End with CNTL/Z.
VSG(config)#
            Step 4   Unregister the old policy agent from VSG. 
            VSG(config)# nsc-policy-agent
VSG(config-nsc-policy-agent)# no policy-agent-image
            Step 5   Register the new policy agent with the VSG. 
            VSG(config-nsc-policy-agent)# policy-agent-image bootflash:vnmc-vsgpa.2.1.1e.bin
VSG(config-nsc-policy-agent)# exit
VSG(config)#
            Step 6   Copy the current running configuration to the startup configuration. 
            VSG(config)# copy running startup
[########################################] 100%
            Step 7   Verify the updated policy agent version.
