new engine ID at bootup. To prevent this from happening, create a new engine ID or a new stack MAC address to save the engine
ID to the startup configuration. This should be done before the SNMPv3 user is created.
If a new active controller is elected (for example, the standby controller becomes the active controller), you will see the following
results:
• If you have configured the engine ID and saved it to the startup configuration file, the new stack configuration uses the
saved engine ID.
• If you have not configured an engine ID, but a stack MAC address is configured, the new stack configuration retains the
original engine ID because it is based on the stack MAC address.
• If you have not configured an engine ID and no stack MAC address is configured, the new stack configuration uses the
default engine ID. The default engine ID is based on the stack's own management MAC address for the new active
controller. Because the engine ID has changed, any SNMPv3 clients must be reconfigured with the new engine ID.

Displaying stack information

This section describes the show commands for a stack and includes output examples and field descriptions.

Displaying stacking topology

The show stack connection command displays the topology and a detailed connection report. It also displays connection errors
or hardware failures as shown in the following sample output.
