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.

 is a number from 0 to 65535. This is equivalent to setting

the MIB variable dot1dStpPriority (RFC 1493).

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.

 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 <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.

 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.
