2.11.3

The Switch MAC Table of MES2110 base on the SVL (Shard VLAN Learning) structure.

Therefore, in order to allow each VLAN client to only receive multicast packets that is

identical to its VLAN ID, we have to use the stricter VLAN Configuration(Cisco Rule),

which has the three following rules:

1. Each port can be under only a single VLAN Access Port (Untagging)

2. Each port can be under multiple VLAN Trunk Port (Tagging)

3. The PVID of Access Port (Untagging) must be identical to its VLAN

Scenario

Description

Use this to enable or disable IGMP snooping, forwarding group

multicast traffic only to ports that are members of that group.

Auto: the Switch learns multicast group membership information of any

VLANs automatically.

Fixed: the Switch only learns multicast group membership information

of the VLAN(s) that you specify below.

Remove: User can remove VLAN multicast group.
