    Configuring a Layer 2 Protocol to be Tunneled in ACX Series

    You can configure L2PT only on Layer 2 ports. To configure L2PT, you must specify any of the following protocols that is to be tunneled:

    • cdp—Cisco Discovery Protocol.
    • stp—All versions of the spanning-tree protocol.
    • vtp—Tunnel the VLAN trunk protocol.
    • ieee802.1x—Tunnel the IEEE 802.1X authentication
    • ieee802.3ah—Tunnel the IEEE 802.3ah Operation, Administration, and Maintenance (OAM) link fault management (LFM)
    • elmi—Tunnel the Ethernet local management interface protocol
    • lacp—Tunnel the Link Aggregation Control Protocol
    • lldp—Tunnel the Link Layer Discovery Protocol
    • mmrp—Tunnel the Multiple MAC Registration Protocol
    • mvrp—Tunnel the Multiple VLAN Registration Protocol

    To specify the protocol that will be tunneled by the Layer 2 protocol tunneling, you can include the protocol (cdp | stp | vtp | ieee802.1x | ieee802.3ah | elmi | lacp | lldp | mmrp | mvrp) statement at the [edit protocols layer2-control mac-rewrite interface ge-fpc/pic/port] hierarchy level.

    Note: When CDP, STP, VTP, IEEE 802.1x, IEEE 802.3ah, E-LMI, LACP, LLDP, MMRP, or MVRP is configured for tunneling on a customer-facing port in a provider bridge, the corresponding protocol should not be enabled for operation on that interface.
