This document contains the following sections:
Release 3.0.1.10 of the Integrated Management Controller (IMC) Release Notes provide additional information to the Release 3.0 IMC documentation.
This document is intended for customer functional and operational groups and engineers responsible for installing and provisioning Cisco MGX 8240 switches.
This section lists the system requirements needed to deploy the IMC cards.
Release 3.0.1.10 supports all hardware components of Release 3.0.
Release 3.0.1.10 IMC software replaces previous versions.
Release 3.0.1.10 software provides an upgrade capability from Release 2.X and Release 3.0. The procedure is the same for both releases. The software preserves configuration across the upgrade on deployed switches.
 |
Note Release 3.0 does not support the upgrade feature in a redundancy configuration. Therefore, users running Release 2.X must upgrade to 3.0.1. |
The software also supports downgrading from Release 3.0.1.10 to Releases 3.0 and 2.X. The configuration changes made in Release 3.0.1.10 are lost after the downgrading process completes. For information on downgrading IMC cards, see the Downgrade to a Previous Software Version section.
Use the VCLI to upgrade the switch software on IMC cards.The procedure is the same for an individual IMC card and cards in a redundancy group. The upgrade causes management traffic to be lost for approximately five minutes for an individual card and 10 minutes for a redundancy group card. User traffic is not interrupted.
In addition to installing new files, the upgrade procedure copies the current configuration to the upgraded switch software. After the cards in a redundancy group are upgraded, IMC redundancy is automatically restored.
To upgrade IMC cards, complete the following procedure.
Step 1 Run the VCLI version that is being upgraded (Release 2.X or 3.0).
Step 2 Set the VCLI image directory environment.
sw1[..] VCLI>> change env -imagedir /opt/Sentient/vcli/image/R3.0.1.10
Step 3 Set the SNMP time out for 99 seconds.
sw1[..] VCLI>> change env -snmptimeout 99
Step 4 Set the network time out of 5 minutes.
sw1[..] VCLI>> change env -timeout 5
Step 5 Verify the changes.
sw1[..] VCLI>> sh env
sw1[..] VCLI>> sh env
AutoSave: Enabled Timeout: 5 min PageLimit: 0 lines
Snmp Timeout: 99 Provisioning Client Path:
Log Level: 0 Software image path: /users/prameet/tmp/R3.0.1.10
ATM Switch Provisioning: Enabled
Step 6 Set the FTP password for the switch.
sw1[..] VCLI>> change system switch -sname <switch name> -ftppass <FTP password>
-card <card number>
If the <FTP password> is not specified, the VCLI uses the default password sysadmin.
Step 7 Start the upgrade.
sw1[..] VCLI>> download -sname <switch name> -verbose 1 -noconfirm 1 -card <card number>
The -verbose 1 option reports the status of the upgrade during the process. The -noconfirm 1 option turns off the confirmation message that displays when the download starts.
If an error occurs during the download, the switch is unreachable. To restart the upgrade procedure, repeat Step 7.
Step 8 Change the old image to the new image.
sw1[..] VCLI>> change imccard image -sname <switch name> -card <card number>
To acknowledge the upgrade and confirm communication loss, type Y at the corresponding prompts. To cancel the upgrade and exit the download process, type N at the prompts.
The change image process includes the following tasks:
The card resets and is unavailable while it completes the following functions:
The change image process takes approximately five minutes for an individual IMC card. This process takes approximately 10 minutes for cards in a redundancy group. During this process, the following errors might occur:
Step 9 When the switch is back online and the upgrade is complete, verify that the switch software is updated to Release 3.0.1.10 for each card.
sw1[..] VCLI>> sh imc info -card <card number>
sw1[..] VCLI>> sh imc info -card 1

To downgrade IMC cards, follow the steps in the Downgrade to a Previous Software Version section.
Release 3.0.1.10 software supports downgrading from Release 3.0.1.10 to Releases 2.X and 3.0. The procedure is the same for both releases. The configuration changes made in Release 3.0.1.10 are lost after the downgrade process completes.
The software also supports upgrading from Release 2.X and Release 3.0 to Release 3.0.1.10. For information on upgrading IMC cards, see the Upgrade to a New Software Release section.
The downgrade procedure is the same for an individual IMC card and cards in a redundancy group.
The downgrade takes approximately five minutes per card, and interrupts management traffic for approximately 1-15 seconds per card. IMC redundancy is restored once the downgrade is complete.
To downgrade IMC cards, complete the following procedure.
Step 1 Change the active software to the previous version of software.
sw1[..] - VCLI>> change imccard image -sname <switch name> -card <card number> -noconfirm 1
To acknowledge the upgrade and confirm communication loss, type Y at the corresponding prompts. To cancel the upgrade and exit the download process, type N at the prompts. These prompts display for each card.
The -noconfirm 1 option turns off the confirmation message that displays when the download starts.
During the downgrade, the IMC card loads the previous software and configuration, and performs diagnostics.
Step 2 When the switch is back online and the downgrade is complete, verify that the switch software is downgraded to either Release 2.2.0.17 or Release 3.0.0.X.
sw1[..] VCLI>> sh imc info -card <card number>
