Disabling the Spanning Tree Protocol
To disable STP on the switch, use the NO SPANNING-TREE STP
ENABLE command in the Global Configuration mode. Here is the
command:
awplus> enable
awplus# configure terminal
awplus(config)# no spanning-tree stp enable
Note
Before disabling the spanning tree protocol on the switch, display
the STP states of the ports and disconnect the network cables from
any ports that are in the discarding state. Ports that are in the
discarding state begin to forward traffic again when STP is disabled.
Leaving the cables connected may result in broadcast storms from
network loops. To view the states of the ports, refer to “Displaying
STP Settings” on page 588.
