Licensing Requirements and Limitations for Layer 2 Protocol Tunneling
Involved Network Elements
Other network elements are not required.
License Requirements
Layer 2 protocol tunneling is a basic function of the switch, and as such is controlled by the license for basic software functions. The license for basic software functions has been loaded and activated before delivery. You do not need to manually activate it.

Feature Limitations
- The device transparently transmits a maximum of 512 Layer 2 protocol packets per second. Excess packets are discarded.
- Do not replace the destination MAC addresses of STP, GVRP, and GMRP packets with the same multicast MAC address.
- Do not replace the destination MAC addresses of EOAM3ah, LACP, and DLDP packets with the same multicast MAC address.
When configuring Layer 2 protocol tunneling, do not use the following multicast MAC addresses to replace the destination MAC address of Layer 2 protocol packets:
- Destination MAC addresses of BPDUs: 0180-C200-0000 to 0180-C200-002F
- Destination MAC address of Smart Link packets: 010F-E200-0004
- Special multicast MAC addresses: 0100-0CCC-CCCC and 0100-0CCC-CCCD
- Common multicast MAC addresses that have been used on the device
Multicast resources are shared by multiple services including VLAN, MAC, Eth-Trunk, M-LAG, Layer 2 protocol transparent transmission, Layer 3 physical interface, and multicast. If multicast resources in the system are insufficient for any of these services you are configuring, the system will display a configuration failure message. To solve this problem, you can delete some unnecessary service configuration, for example, delete unused VLANs.
