Command History
Usage Guidelines When the number of packets is exceeded, the port is put in error-disabled state.
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 packets value 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 tunneling.
lldp (Optional) Specifies LLDP tunneling.
stp (Optional) Specifies STP tunneling.
vtp (Optional) Specifies VTP tunneling.
packets Shutdown threshold; valid values are from 1 to 4096.
