- Backup—Provides a backup path to the designated port path toward
the Spanning Tree leaves. Backup ports occur only when two ports are
connected in a loop by a point-to-point link, or when a LAN has two or
more connections connected to a shared segment.
- Disabled—The port is not participating in the Spanning Tree.
• Mode—Indicates whether the RSTP administrative mode is enabled or
disabled for the port.
• Edge Port Operational Status—If enabled for the port or LAG, the port is
automatically placed in the forwarding state. See
Interface Settings
• Port Status—The operational state of the port.
You can select a port and click Activate Protocol Migration to have the switch
send RSTP BPDUs to the port. This can be used to test whether all legacy bridges
on the LAN have been removed.
