Configuring L2PT (Only for Certain Devices) L2PT Configuration
Step 2 l2protocol-tunnel
Enable the L2PT feature globally.
Step 3 interface { fastEthernet

}
Enter interface configuration mode.
Step 4 l2protocol-tunnel type uni { 01000ccccccc | 01000ccccccd | gvrp | stp | lacp | all } [
threshold
threshold
]
Configure the port as a UNI port, specify the Layer 2 protocol types of the packets that can
be transparently transmitted on the port, and set the threshold for packets-per-second
accepted for encapsulation on the UNI port.
01000ccccccc: Enable protocol tunneling for the packets with their destination MAC
address as 01000CCCCCCC, which includes CDP, VTP, PAgP and UDLD.
01000ccccccd: Enable protocol tunneling for the PVST+ packets with the destination MAC
address as 01000CCCCCCD.
gvrp: Enable protocol tunneling for the GVRP packets.
stp: Enable protocol tunneling for the STP packets.
lacp: Enable protocol tunneling for the LACP packets.
all: All the above Layer 2 protocols are supported for tunneling.
threshold:
Set a threshold which determines the maximum number of packets to be
processed for the specified protocol on the port in one second. When the threshold is
exceeded, the port drops the specified Layer 2 protocol packets. The valid values are from
1 to 1000 (packets/second). 0 indicates that the threshold feature is disabled.
Step 5 exit
Return to global configuration mode.

}
Enter interface configuration mode.
Step 7 l2protocol-tunnel type nni
Configure the port as an NNI port.
Step 8 show l2protocol-tunnel global
Verify the global L2PT configuration.
Step 9 show l2protocol-tunnel interface [ fastEthernet
