MULTILINK ML810 MANAGED EDGE SWITCH – INSTRUCTION MANUAL
The MultiLink ML810 Managed Edge Switch supports IGMP version 1 and version 2. The
switch can act either as a querier or a nonquerier. The querier router periodically sends
general query messages to solicit group membership information. Hosts on the network
that are members of a multicast group send report messages. When a host leaves a group,
it sends a leave group message. The difference between Version 1 and Version 2 is that
version 1 does not have a "Leave" mechanism for the host. The MultiLink ML810 Managed
Edge Switch does pruning when there is a leave message or a time expires on a port, we
prune the multicast group membership on that port.
1. The MultiLink ML810 Managed Edge Switch supports only the default VLAN. It
can be enabled within a port VLAN, tagged VLAN, or no VLAN. It can snoop up
to 256 multi-cast Groups.
2. IGMP is disabled as a default. It has to be enabled to leverage the benefits of
IGMP.
3. The MultiLink ML810 Managed Edge Switch supports only the default VLAN. It
can be enabled within a port VLAN, tagged VLAN, or no VLAN. It can snoop up
