Uplink Fast Convergence
Uplink fast convergence enables a DWS-1008 switch that has redundant links to the network
core to immediately change the state of a backup link to forwarding if the primary link to the
root fails. Uplink fast convergence bypasses the listening and learning states to immediately
enter the forwarding state.
Note: The uplink fast convergence feature is applicable to bridges that are acting as access
switches to the network core (distribution layer) but are not in the core themselves. Do not
enable the feature on DWS-1008 switches that are in the network core.
Configuring Port Fast Convergence
To enable or disable port fast convergence, use the following command:
set spantree portfast port port-list {enable | disable}
To enable port fast convergence on ports 2, 4, and 6, type the following command:
DWS-1008# set spantree portfast port 2,4,6 enable
success: change accepted.
Displaying Port Fast Convergence Information
To display port fast convergence information, use the following command:
show spantree portfast [port-list]
To display port fast convergence information for all ports, type the following command:
DWS-1008# show spantree portfast
