SNMP agent and RMON MIB. In the device, SNMP agent is a client software which is
operating over SNMP protocol used to receive the command from SNMP manager (server
site) and echo the corresponded data, i.e. MIB object. Besides, SNMP agent will actively
issue TRAP information when happened.
RMON is the abbreviation of Remote Network Monitoring and is a branch of the SNMP
MIB.
The device supports MIB-2 (RFC 1213), Bridge MIB (RFC 1493), RMON MIB (RFC
1757)-statistics Group 1,2,3,9, Ethernet-like MIB (RFC 1643), Ethernet MIB (RFC 1643)
and so on.

Support IGMP version 2 (RFC 2236): The function IGMP snooping is used to establish the
multicast groups to forward the multicast packet to the member ports, and, in nature, avoid
wasting the bandwidth while IP multicast packets are running over the network.

The implementation of IP multicast processing. The switch supports IGMP version 1 and
IGMP version 2, efficient use of network bandwidth, and fast response time for channel
changing. IGMP version 1 (IGMPv1) is described in RFC1112 ,and IGMP version 2
(IGMPv2) is described in RFC 2236. Hosts interact with the system through the exchange
of IGMP messages. Similarly, when you configure IGMP proxy, the system interacts with
the router on its upstream interface through the exchange of IGMP messages. However,
when acting as the proxy, the system performs the host portion of the IGMP task on the
upstream interface as follows:
When queried, sends group membership reports to the group.
