    • Ethernet Local Management Interface (E-LMI)

    • Generic Attribute Registration Protocol (GARP) VLAN Registration Protocol (GVRP)

    • IEEE 802.1X authentication

    • IEEE 802.3AH Operation, Administration, and Maintenance (OAM) link fault management (LFM)

    • Link Aggregation Control Protocol (LACP)

    • Link Layer Discovery Protocol (LLDP)

    • Multiple MAC Registration Protocol (MMRP)

    • Multiple VLAN Registration Protocol (MVRP)

    • Unidirectional Link Detection (UDLD)

    • VLAN Spanning Tree Protocol (VSTP)
