OS name 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. 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 name 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 version" NX-OS command to capture hardware/software information such as vendor name, OS name, OS version and hostname.
