    • Generic VLAN Registration (GVRP) — Protocols for automatically propagating and configuring VLAN in a bridged domain
    • DHCP Relay (Layer 2) — Relay of DHCP traffic to DHCP server in different VLAN; works with DCHP Option 82
    • IGMP v1/v2/v3 Snooping
      — Limits bandwidth-intensive multicast traffic to only the requesters
      — Supports 1024 multicast groups (source-specific multicast is also supported)
    • IGMP Querier — It is used to support a Layer 2 multicast domain of snooping switches in the absence of a multicasst router
    • IGMP Proxy — Supported
    • MLD v1/v2 SNooping — Delivers IPv6 multicast packets only to the required receivers
  • Security
    • Security Shell (SSH) Protocol — Secures telnet traffic in/out of the switch; SSH v1 and v2 are supported
    • Secure Sockets Layer (SSL) — SSL encrypts the http traffic, allowing advanced secure access to the browser-based management GUI in the switch
    • IEEE 802.1X
      — RADIUS Authentication, Authorization and Accouting
      — MD5 hash
      — guest VLAN
      — single/Multiple host mode and single/multiple sessions
      — Supports IGMP-RADIUS based 802.1X
      — Dynamic VLAN assignment
    • Layer 2 Isolation Private VLAN Edge (PVE) — PVE (also known as protected ports) provides L2 isolation between clients in the same VLAN; supports multiple uplinks
    • Port Security — Locks MAC addresses to ports, and limits the number of learned MAC addresses
    • IP Source Guard — Prevents illegal IP address from accessing to specific port in the switch
    • TACACS+ — Supports TACACS+ authentication; switch as a client
    • Storm Control — Prevents traffic on a LAN from being disrupted by a broadcast, multicast, and/or unicast storm on a port
    • ACLs
      — Supports up to 256 entries
      — Drop or rate limitation based on source and destination MAC, VLAN ID or IP address, protocol, port, differentiated services code point (DSCP)/IP precedence, TCP/UDP source and destination ports, 802.1p priority, Ethernet type, Internet Control Message Protocol (ICMP) packets, IGMP packets, TCP flag
  • Quality of Service
    • Hardware Priority Queue — Supports 8 hardware queues
    • Scheduling
      — Strict priority and weighted round-robin (WRR)
      — Queue assignment based on DSCP and Class of Service (802.1p/CoS)
    • Classification — Port based; 802.1p VLAN priority based; IPv4/IPv6 precedence/type of Service (ToS)/DSCP based; Differentiated Services (DiffServ); classification and remarking ACLs, trusted QoS
