You can discover stack switches via Add Device or Network Discovery page just like every other device. Click here to learn more about device discovery in OpManager.
For now, OpManager only supports Cisco switch stacks. For Cisco switch monitoring, switches other than the below mentioned device types will be discovered as a normal switch.
Listed below are the various member state displayed in OpManager. This can be viewed under the Stack switch details widget in the stack switch snapshot page.
| State | Description |
| Waiting | Waiting for a limited time on other switches in the stack to come online |
| Progressing | Master election or mismatch checks in progress |
| Added | The switch is added to the stack |
| Ready | The switch is operational |
| Removed | The switch is removed from the stack |
| Provisioned | The switch is not an active member of the stack. |
| Invalid | The switch's state machine is in invalid state. |
| sdmMismatch | The SDM template configured on the master is not supported by the new member |
| verMismatch | The OS version running on the master is different from the on this member |
| featureMismatch | Some of the features configured on the master are not supported by this member |
| newMasterInit | Waiting for the new master to finish initialization after master switchover (Master Re-Init) |
Check if the associated SNMP/CLI credential is correct. Also query the below OIDs from Settings -> Tools -> MIB Browser and check the response.
