C H A P T E R 3 Console Command Reference

set-br-prio

set-br-prio <priority>

Sets the spanning tree bridge priority. Bridge priority forces a bridge to be selected as the root bridge, or as a designated bridge. The bridge priority is a value used in determining the identity of the root bridge. The bridge with the lowest value has the highest priority and will be selected as the root.

priority is a number from 0 to 65535. This is equivalent to setting the MIB variable dot1dStpPriority (RFC 1493).

set-br-maxage

set-br-maxage <maxage>

Sets the spanning tree bridge maximum age. Max age is the maximum time in seconds a bridge waits without receiving spanning tree configuration messages before attempting a reconfiguration. This parameter takes effect when a bridge is operating as the root bridge. Bridges not acting as the root use the root bridge’s Max Age parameter.

maxage is in seconds, from 6 to 40. However, the corresponding MIB variable, dot1dStpBridgeMaxAge (RFC 1493), is in hundreths of seconds, ranging from 600 to 4000, and must be a multiple of 100.

set-br-hellot

set-br-hellot <hello_time>

Sets the spanning tree bridge hello time. Hello time is the interval between transmission of spanning tree configuration messages in seconds. All bridges send configuration messages during reconfiguration to select the designated root bridge (in this case, the switch port). Ports not acting as a root bridge use the root bridge hello-time value. After this is determined, only designated bridges (ports) send configuration messages.

hello_time is a number from 1 to 10 in seconds. However, the corresponding MIB variable, dot1dStpBridgeHelloTime (RFC 1493), is in hundreths of seconds ranging from 100 to 1000, and must be a multiple of 100.
