A switch stack is a method of grouping or bridging several switches in a way that they act as one single switch, with the aim of delivering maximum scalability and performance. This manner of stacking is generally regarded as the most effective way of scaling up the capacity of a network.
OpManager's Switch stack monitoring feature helps you discover and monitor your switch stacks for their health and optimum performance and receive alarms. This helps you initiate corrective actions at the earliest, enabling faster troubleshooting.
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.
Once the switch stack is discovered by using the management IP, OpManager starts monitoring it using SNMP protocol. Furthermore, the switch stacks will be polled at regular intervals to know if there has been any changes made.

Note: Switches other than the ones mentioned above, will be discovered and classified as a normal switch for switch monitoring. Apart from the above-mentioned switches, users can also customize their supported models by providing the SysOID and the device type of their preferred stack switch.
Listed below are the various member states 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. |
| SDM Mismatch | The SDM template configured on the master is not supported by the new member |
| Version Mismatch | The OS version running on the master is different from the on this member |
| Feature Mismatch | Some of the features configured on the master are not supported by this member |
| Master Re-Init | Waiting for the new master to finish initialization after master switchover |
SWITCHSTACK_STANDBYROLE_SEV ClearAttention | Critical | Trouble | ClearSTACKROLE_SUPPRESS_ALARM falsefalse will generate an alert based on severity whenever a switch role changes.Note: OpManager should be restarted for the changes to take effect.
