awplus(config)#
Set the priority for the device to become the root bridge
for the CIST.
Specify the bridge priority in the range 0 to 61440. If you
enter a number that is not a multiple of 4096, the switch
rounds the number down.
Configure edge ports
If some switch ports are connected to devices that cannot generate BPDUs (such as workstations), you can set
particular switch ports as edge ports, or set them to automatically detect whether they are edge ports.
awplus(config)#
interface
Enter Interface Configuration mode for these switch
ports.
awplus(config-if)#
spanning-tree edgeport (RSTP and

awplus(config-if)#
spanning-tree autoedge (RSTP and
Set these ports to be edge ports,
or
set these ports to automatically detect whether they are
edge ports.
Configure Root Guard
awplus(config-if)#
The Root Guard feature makes sure that the port on
which it is enabled is a designated port. If the Root
Guard enabled port receives a superior BPDU, it goes to
a Listening state (for STP) or discarding state (for RSTP
and MSTP). Enable the Guard Root feature if required.
awplus(config-if)#
exit
Return to Global Configuration mode.
Configure BPDU Guard
awplus(config)#
spanning-tree portfast bpdu-guard
If required, enable the BPDU Guard feature.
awplus(config)#
spanning-tree errdisable-timeout
Set a timeout for ports that are disabled due to the BPDU
guard feature.
awplus(config)#
spanning-tree errdisable-timeout
Specify the time interval after which a port is brought
back up when it has been disabled by the BPDU guard
feature.
