SSE-G2252/SSE-G2252P Switches User's Manual
MVR maintains the user isolation and data security provided by VLAN segregation by
passing only multicast traffic into other VLANs to which the subscribers belong. Even
though common multicast streams are passed onto different VLAN groups from the
MVR VLAN, users in different IEEE 802.1Q or private VLANs cannot exchange any
information (except through upper-level routing services).

• General Configuration Guidelines for MVR:
1. Enable MVR globally on the switch, select the MVR VLAN, and add the multicast
groups that will stream traffic to attached hosts (see
Settings" on page
2. Set the interfaces that will join the MVR as source ports or receiver ports (see
"Configuring MVR Interface Status" on page
3. For multicast streams that will run for a long term and be associated with a stable
set of hosts, you can statically bind the multicast group to the participating interfaces
(see "Assigning Static Multicast Groups to Interfaces" on page
• Although MVR operates on the underlying mechanism of IGMP snooping, the two
features operate independently of each other. One can be enabled or disabled
without affecting the behavior of the other. However, if IGMP snooping and MVR are
both enabled, MVR reacts only to join and leave messages from multicast groups
configured under MVR. Join and leave messages from all other multicast groups are
managed by IGMP snooping. Also, note that only IGMP version 2 or 3 hosts can
issue multicast join or leave messages. If MVR must be configured for an IGMP
version 1 host, the multicast groups must be statically assigned (see
Static Multicast Groups to Interfaces" on page
