OS version mismatch across cluster members for Cisco

Vendor

Cisco

Description

Indeni will identify when two devices are part of a cluster and alert if the OS installed is different.

Remediation Steps

Install the correct versions of software on each device.

1. Check that the vPC peers have the same NX-OS version except during the non-disruptive upgrade, that is, In-Service Software Upgrade (ISSU).

2. Execute the "show version" NX-OS command and check the installed NX-OS version across the vPC peer switches.

3. Login to the Cisco Software Download center (a CCO account is required) and check the available NX-OS releases for your devices. Further information can be found to the next link: https://software.cisco.com/download/navigator.html?mdfid=268437593&flowid=4466

4. Select the NX-OS release highlighted with a star icon and download it. This is the currently recommended NX-OS version by Cisco.

5. Review the Release Notes for this release for any bug and unsupported feature. If this NX-OS release does not support features which are already deployed at the current configuration a more recent NX-OS release should be used.

6. Schedule a Maintenance Window for NX-OS upgrade in order the vPC peer switches have exact the same NX-OS version.

NOTE: The vPC could be established between the vPC peers with not exact the same NX-OS release but several problems will be faced when new features are configured. For instance FEX-mismatch SW log message will be generated if you try to connect a FEX via vPC to a pair of vPC switches with different SW version. In this case the FEX will be operational only from one of the vPC peer switches.

How does this work?

This script logs in to the Cisco Nexus switch using SSH and retrieves the output of the "show version" command. The output includes the device's hardware and software related details.

Why is this important?

This script logs in to the Cisco Nexus switch using SSH and retrieves the output of the "show version" command. The output includes the device's hardware and software related details.

Without Indeni how would you find this?

The administrator would have to manually log into the Nexus switch and run the "show verion" NX-OS command to capture hardware/software information such as vendor name, OS name, OS version and hostname.
