spanning-tree uplinkfast
Do not enable the root guard on interfaces that will be used by the UplinkFast feature. With UplinkFast,
the backup interfaces (in the blocked state) replace the root port in the case of a failure. However, if root
guard is also enabled, all the backup interfaces used by the UplinkFast feature are placed in the
root-inconsistent state (blocked) and prevented from reaching the forwarding state.
If you set the max-update-rate to 0, station-learning frames are not generated, so the spanning-tree
topology converges more slowly after a loss of connectivity.
Examples This example shows how to enable UplinkFast:
Switch(config)# spanning-tree uplinkfast
You can verify your setting by entering the show spanning-tree summary privileged EXEC command.
Related Commands Command Description
show spanning-tree summary Displays a summary of the spanning-tree interface states.
spanning-tree vlan root primary Forces this switch to be the root switch.
