4.5.3 Configuring Spanning Tree
To configure the spanning tree protocol, carry out the following procedure in the administrator EXEC mode.
Command
Task
xg# configure terminal
Switch to global configuration mode.
xg(config)# spanning-tree enable
Enable Spanning Tree Protocol.
xg(config)# spanning-tree priority <0-61440>
xg(config)# spanning-tree hello-time <1-10>
xg(config)# spanning-tree max-age <6-40>
xg(config)# spanning-tree forward-time <4-30>
Configure Spanning Tree Protocol parameters on the
XG1200.
Switch priority
Hello time
Maximum aging time (max-age)
Forward delay time (forward-time)
xg(config)# interface port 1 2 3
xg(config)# interface port range 1 3
Switch to interface edit mode to configure spanning
tree-related parameters for port.
In this example, the global interface configuration mode
is selected for ports 1 through 3.
xg(config-if)# spanning-tree protocol { rstp |
none }
Set a spanning tree protocol mode that corresponds to
each port.
xg(config-if)# spanning-tree port-priority
<0-240>
xg(config-if)# spanning-tree port-path-cost
<1-200000000>
Configure the following parameters related to the
spanning tree topology:
Port priority
Path cost
xg(config-if)# spanning-tree portfast
(Optional)
If the port is configured as an edge port(*), it is possible
to make settings that can reduce the time taken to
transit into forwarding state.
* It is available only when the port is directly connected
to an end terminal that has no influence on the spanning
tree configuration.
xg(config-if)# exit
Exit to global configuration mode.
xg(config)# exit
Exit to administrator EXEC mode.
xg# show spanning-tree [ detail ]
View the state of the spanning tree.
