Hi everyone,


Cloud engine 6800 series does not support VCMP. How can I use l2protocol-tunnel to transparently transmit Layer 2 protocol packets for VCMP.

I have try this but VCMP is not documented enough. What I need is marked in red.

l2protocol-tunnel user-defined-protocol vcmp protocol-mac protocol-mac encap-type llc dsap dsap-value ssap ssap-value group-mac group-mac


Thanks for your help.

Hi @exploitdsi
for VCMP, the destination MAC is 0118-8255-5555, you can try configure the protocol-mac and group-mac to 0118-8255-5555, the dsap-value and ssap-value is not mandatory, you can ignore them.

Hi,

Following is the complete syntax:
l2protocol-tunnel user-defined-protocol protocol-name protocol-mac protocol-mac [ encap-type { { ethernetii | snap } protocol-type protocol-type-value | llc dsap dsap-value ssap ssap-value } ] group-mac { group-mac | default-group-mac }
undo l2protocol-tunnel user-defined-protocol protocol-name

Description: The l2protocol-tunnel user-defined-protocol command defines characteristic information about a user-defined Layer 2 protocol, including the protocol name, Ethernet encapsulation format, destination MAC address, and MAC address that replaces the destination MAC address of Layer 2 protocol packets.
The undo l2protocol-tunnel user-defined-protocol command deletes characteristic information about a user-defined Layer 2 protocol.
By default, no characteristic information about a user-defined Layer 2 protocol exists on the CloudEngine 8800, 7800, 6800, and 5800 series switches.

I hope it helps. However, if you want to further get clarification, please visit following link for detailed description of each parameter of this:

Hi Umaryaqub,

Thanks for your answer. Right that what I have found. But especially for VCMP what could be:
- protocol-mac
- dsap-value
- ssap-value
- group-map
I couldn’t find any of these parameters...

Hi @chenhui,

Thanks for your comment. According to this documentation:
https://support.huawei.com/enterprise/en/doc/EDOC1000114005/44dfddd0/overview-of-vcmp
you right with the destination MAC but if I set the same MAC for protocol-mac and group-mac I got an error (Error: The group-mac conflicts with the existing protocol-mac.)
