WDS and STP

Using the CLI to Configure STP

If a radio interface is set to the Bridge or Root Bridge role, STP can be enabled on the access point to maintain a valid network topology. To globally enable STP, use the bridge stp enable command from the CLI configuration mode. Then, configure the other global STP parameters for the bridge. The path cost and priority for each bridge link can be set using the bridge‐link path‐cost and bridge‐link port‐priority command from the Wireless Interface configuration mode. The path cost and priority can also be set for the Ethernet port from the Ethernet Interface configuration mode. To view the current STP settings, use the show bridge stp command.

Example

RoamAbout 4102#configure

Enter configuration commands, one per line. End with CTRL/Z

RoamAbout 4102(config)#bridge stp enable

RoamAbout 4102(config)#bridge stp forwarding-delay 25

RoamAbout 4102(config)#bridge stp hello 5

RoamAbout 4102(config)#bridge stp max-age 40

RoamAbout 4102(config)#bridge stp pri 40000

RoamAbout 4102(config)#interface wireless a

Enter Wireless configuration commands, one per line.

RoamAbout 4102(if-wireless a)#bridge-link path-cost 2 40

RoamAbout 4102(if-wireless a)#bridge-link port-priority 2 64

RoamAbout 4102(if-wireless a)#exit

RoamAbout 4102#show bridge stp
