Multicast VLAN Registration for IPv4
– 573 –
COMMAND USAGE
u General Configuration Guidelines for MVR:
1. Enable MVR for a domain on the switch, and select the MVR VLAN
(see "Configuring MVR Domain Settings" on page 575).
2. Create an MVR profile by specifying the multicast groups that will
stream traffic to attached hosts, and assign the profile to an MVR
domain (see "Configuring MVR Group Address Profiles" on
page 577).
3. Set the interfaces that will join the MVR as source ports or receiver
ports (see "Configuring MVR Interface Status" on page 580).
4. 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 MVR
Multicast Groups to Interfaces" on page 582).
u 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.
CONFIGURING MVR
GLOBAL SETTINGS
Use the Multicast > MVR (Configure Global) page to configure proxy
switching and the robustness variable.

PARAMETERS
These parameters are displayed:
u Proxy Switching – Configures MVR proxy switching, where the source
port acts as a host, and the receiver port acts as an MVR router with
querier service enabled. (Default: Enabled)
n
When MVR proxy-switching is enabled, an MVR source port serves
as the upstream or host interface, and the MVR receiver port serves
as the querier. The source port performs only the host portion of
MVR by sending summarized membership reports, and
automatically disables MVR router functions.
n
Receiver ports are known as downstream or router interfaces.
These interfaces perform the standard MVR router functions by
maintaining a database of all MVR subscriptions on the downstream
interface. Receiver ports must therefore be configured on all
downstream interfaces which require MVR proxy service.
