This monitors the status of a switch in the stack for any Cisco stack switch. Below are the different options you can use to monitor. I used Value 4, and made an alert saying if Value 4 is not returned when querying the above OID, send me an alert.


• Waiting – value 1

Waiting for a limited time on other switches in the stack to come online.


• Progressing – Value 2

Master election or mismatch checks in progress.


• Added – Value 3

The switch is added to the stack.


• Ready – Value 4

The switch is operational.


• SdmMismatch – Value 5

The SDM template configured on the master is not supported by the new member.


• VerMismatch – Value 6

The operating system version running on the master is different from the operating system version running on this member.


• FeatureMismatch – Value 7

Some of the features configured on the master are not supported on this member.


• NewMasterInit – Value 8

Waiting for the new master to finish initialization after master switchover (Master Re-Init).


• Provisioned – Value 9

The switch is not an active member of the stack.


• Invalid – Value 10

The switch’s state machine is in an invalid state.


• Removed – Value 11
