Tunneling (L2PT)

config l2protocol_tunnel ports [<portlist> | all] type [uni tunneled_protocol [{stp | gvrp | protocol_mac
[01-00-0C-CC-CC-CC | 01-00-0C-CC-CC-CD]}(1) | all] {threshold <value 0-65535>} | nni | none]
show l2protocol_tunnel {[uni | nni]}
disable l2protocol_tunnel
48-1 config l2protocol_tunnel ports
Description
This command is used to configure Layer 2 protocol tunneling on ports.
Layer 2 protocol tunneling is used to tunnel Layer 2 protocol packet.
If a Layer 2 protocol is tunnel-enabled on an UNI, once received the PDU on this port, the multicast
destination address of the PDU will be replaced by Layer 2 protocol tunneling multicast address. The
Layer 2 protocol tunneling multicast address for STP is 01-05-5D-00-00-00, for GVRP is 01-05-5D-00-
00-21, for Layer 2 protocols MAC 01-00-0C-CC-CC-CC is 01-05-5D-00-00-10 and for protocol MAC
01-00-0C-CC-CC-CD is 01-05-5D-00-00-11.
When QinQ is enabled, an S-TAG will be added to the Layer 2 PDU too. The S-TAG is assigned
according QinQ VLAN configuration.
Format
config l2protocol_tunnel ports [<portlist> | all] type [uni tunneled_protocol [{stp | gvrp |
protocol_mac [01-00-0C-CC-CC-CC | 01-00-0C-CC-CC-CD]}(1) | all] {threshold <value 0-65535>} |
nni | none]
Parameters
ports -Specify the ports on which the Layer 2 protocol tunneling will be configured.
<portlist> - Enter a list of ports to be configured here.
all - Specify to use this configuration on all the ports.
type - Specify the type of the ports.
uni - Specify the port is UNI port
tunneled_protocol - Specify tunneled protocols on this UNI port. If specified all, all tunnel-able Layer
2 protocols will be tunneled on this port.
stp - (Optional) Specify to use the STP protocol.
gvrp - (Optional) Specify to use the GVRP protocol.
protocol_mac - (Optional) Specify which protocol MAC address to use.
