l2protocol-tunnel type uni { 01000ccccccc | 01000ccccccd | gvrp | stp | all }
[ threshold threshold ]
no l2protocol-tunnel
Parameter
nni —— Specify the port type according to its connecting device in the network.
Specify the port’s type as NNI if it is connecting to the ISP network.
uni —— Specify the port type according to its connecting device in the network.
Specify the port’s type as UNI if it is connecting to the user’s local network.
01000ccccccc | 01000ccccccd | gvrp | stp | all —— Select the supported Layer 2
protocol type. Packets of the specified protocol will be encapsulated with their
destination MAC address before they are sent to the ISP network. Packets will
be decapsulated to restore their Layer 2 protocol and MAC address information
before they are sent to the customer network.
• 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.
• gvrp: Enable protocol tunneling for the GVRP packets.
• stp: Enable protocol tunneling for the STP packets.
• all: All the above Layer 2 protocols are supported for tunneling.
threshold ——Configure the threshold for packets-per-second accepted for
encapsulation. Packets beyond the threshold will be dropped.
Command Mode
Interface Configuration Mode (interface gigabitEthernet / interface range
gigabitEthernet / interface port-channel / interface range port-channel)
Privilege Requirement
Only Admin and Operator level users have access to these commands.
Example
Configure port 1/0/3 as a UNI port for STP packets with the threshold as 1000
packets/second:
T2600G-28TS(config)#interface gigabitEthernet 1/0/3
