BPDUGUARD on an interface level

[kanwar]

Hi,

I would like to enable bpduguard on all our trunk ports configured for voice and data traffic on our 3750 switches. I would like to block so no one can plug a switch or a hub.

Thx

Hi Friend,

yes, you can configure the spanning-tree bpdugurad on the trunk interfaces. To configure this feature on per interfaces use the following command.

config t

Switch(config)# interface gigabitethernet2/0/1

Switch(config-if)# spanning-tree bpduguard enable

HTH, Please rate if it does.
