Configuring Q-in-Q Tunnels and Layer 2 Protocol Tunneling
Step 3
switchport
Example:
switch(config-if)# switchport
Sets the interface as a Layer 2 switching port.
Step 4
switchport mode dot1q-tunnel
Example:
switch(config-if)# switchport mode
dot1q-tunnel
Creates a 802.1Q tunnel on the port.
Step 5
l2protocol tunnel drop-threshold [cdp |
stp | vtp] packets-per-sec
Example:
switch(config)# l2protocol tunnel
drop-threshold 3000
Specifies the maximum number of packets that can
be processed on an interface before being dropped.
Optionally, you can specify CDP, STP, or VTP. Valid
values for the packets are from 1 to 4096.
Step 6
no l2protocol tunnel drop-threshold [cdp |
stp | vtp]
Example:
switch(config)# no l2protocol tunnel
drop-threshold
(Optional) Resets the threshold values to 0 and
disables the drop threshold.
Step 7
l2protocol tunnel shutdown-threshold [cdp
| stp | vtp] packets-per-sec
Example:
switch(config)# l2protocol tunnel
shutdown-threshold 3000
Specifies the maximum number of packets that can
be processed on an interface. When the number of
packets is exceeded, the port is put in error-disabled
state. Optionally, you can specify CDP, STP, or VTP.
Valid values for the packets is from 1 to 4096.
Step 8
no l2protocol tunnel shutdown-threshold
[cdp | stp | vtp]
Example:
switch(config)# no l2protocol tunnel
shutdown-threshold
(Optional) Resets the threshold values to 0 and
disables the shutdown threshold.
Step 9
exit
Example:
switch(config)# exit
Exits configuration mode.
Step 10
copy running-config startup-config
Example:
switch# copy running-config startup-config
(Optional) Copies the running configuration to the
