Command History

Usage Guidelines On all the service-provider edge switches, you must enable PortFast BPDU filtering on the 802.1Q

tunnel ports by entering these commands:

Router(config-if)# spanning-tree bpdufilter enable

Router(config-if)# spanning-tree portfast

Note PortFast BPDU filtering is enabled automatically on tunnel ports.

If you do not specify a protocol, the threshold applies to all protocols.

You can configure protocol tunneling on switch ports only. You must enter the switchport command

once without any keywords to configure the LAN port as a Layer 2 interface before you can enter

additional switchport commands with keywords. This action is required only if you have not entered the

switchport command for the interface.

cdp (Optional) Specifies CDP packets.

lldp (Optional) Specifies LLDP packets.

stp (Optional) Specifies STP packets.
