Anyway to stop an interface from SENDing the bpdu?

[Difan Zhao]

The interface is configured as a trunk:

int g1/0/1

switchport trunk encapsulation dot1q

switchport mode trunk

The spanning-tree protocal is MST. Is there anyway to stop this interface from sending out BPDUs? Portfast will only work on Access port...

Thanks!

Depending on your platform/IOS to enable Port Fast on trunk ports, you must use the

-if #spanning-tree portfast trunk

interface configuration command.

If you have redundant trunks, you may want to look into uplinkfast.
