get-st-bcfg get-st-pcfg get-st-syscfg

set-br-prio set-br-maxage set-br-hellot set-br-fwdel set-prt-prio set-prt-enb set-prt-pcost

Displays the spanning tree session state.

Enables or disables the spanning tree for the next session.

Displays the spanning tree bridge parameters.

Displays the spanning tree port parameters table.

Displays the spanning tree system ports configuration.

Sets the spanning tree bridge priority.

Sets the spanning tree bridge maximum age.

Sets the spanning tree bridge hello time.

Sets the spanning tree bridge forward delay.

Sets the spanning tree port priority.

Enables or disables a port spanning tree.

Sets the spanning tree port path cost.

Spanning tree is a protocol that determines which port is turned off in a redundant configuration. Spanning tree is enabled anytime a packet could potentially be caught in an infinite loop on the network (for example, when two switches are connected to each other and also to the same bridge). The protocol uses the port with the lowest-cost path and turns off the other port. If one path fails, the other path is automatically turned on.

Spanning tree is enabled by default. See the “Spanning tree commands” section later in this chapter for more information.
