set-br-fwdel

set-br-fwdel <forward_delay>

Sets the spanning tree bridge forward delay. Forward delay is the time interval in seconds spent waiting to change a port from its spanning tree preforwarding state to a forwarding state. This is necessary because every bridge on the network should ensure no loop is formed before allowing the port to forward packets.

forward_delay is in seconds, from 4 to 30. However, the corresponding MIB variable, dot1dStpBridgeForwardDelay (RFC 1493), is in hundreths of seconds from 400 to 3000, and must be a multiple of 100.

set-prt-prio

set-prt-prio <port_number> <port_priority>

Sets the spanning tree port priority. port_number is the decimal port number, and port_priority is a number from 1 to 255. This is equivalent to setting the MIB variable dot1dStpPortPriority

(RFC 1493).

set-prt-enb

set-prt-enb <port_number> {enabledisable}

Enables or disables a port in the spanning tree. port_number is the decimal port number. This is equivalent to setting the MIB variable dot1dStpPortEnable (RFC 1493).

set-prt-pcost

set-prt-pcost <port_number> <path_cost>

Sets the spanning tree port path cost. port_number is the decimal port number, and path_cost is path cost from 1 to 65535. This is equivalent to setting the MIB variable dot1dStpPortPathCost

(RFC 1493).
