Catalyst switches usually form a stack on boot up, even if they are not stacked. They just form a stack with themselves. So Prime Infrastructure reads out the model of the switch, that says it is a stack. This leads to the fact, that the device model will be displayed as Cisco Catalyst 29xx Stack-able Ethernet Switch in Prime.

There was a fix in IOS that told the switch to not report the stack, but the model via SNMP instead.

no snmp-server sysobjectid type stack-oid

This lead to a clean Prime Infrastructure database.

Now this command is not working on IOS-XE and this leads to the same bad database issue we have had in the past:

Does anybody know a fix for this in IOS-XE?

  • "Catalyst switches usually form a stack on boot up, even if they are not stacked." What does that mean? I can install a bunch of stackable switches without actually creating a stack, and the switches do not form a stack, even if they are directly connected to each other.

  • @RonTrunk: I am guessing it affects all XE versions, but i tested 16.6.4 & 16.09.06

  • @RonMaupin: While booting up you can see this line in the log: %STACKMGR-4-SWITCH_ADDED: Switch 1 has been ADDED to the stack and if you issue show switch you can see that there is a stack with one member only.

  • Right, a single stack switch is a stack with one member, but the switches do not form stacks with other stack switches, they are, themselves, stacks, and I would want that reported as such because if you add more switches to the stack, you would only see the stack as a single switch.
