Multicast Vlan Registration; Mvr - Supermicro SSE-G2252 User Manual

38-4 Multicast VLAN Registration

This section describes commands used to configure Multicast VLAN Registration
(MVR). A single network-wide VLAN can be used to transmit multicast traffic (such as
television channels) across a service provider's network. Any multicast traffic entering
an MVR VLAN is sent to all subscribers. This can significantly reduce to processing
overhead required to dynamically monitor and establish the distribution tree for a normal
multicast VLAN. Also note that 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.

Command

mvr

mvr immediate-leave

mvr vlan group
show mvr
mvr
This command enables Multicast VLAN Registration (MVR) globally on the switch,
statically configures MVR multicast group IP address(es) using the group keyword, or
specifies the MVR VLAN identifier using the vlan keyword. Use the no form of this
command without any keywords to globally disable MVR. Use the no form with the
group keyword to remove a specific address or range of addresses. Or use the no form
with the vlan keyword to restore the default MVR VLAN.
Syntax
[no] mvr [group ip-address [count] | vlan vlan-id]
group - Defines a multicast service sent to all attached subscribers.
ip-address - IP address for an MVR multicast group.
(Range: 224.0.1.0 - 239.255.255.255)
count - The number of contiguous MVR group addresses. (Range: 1-1024)
vlan - Specifies the VLAN through which MVR multicast data is received. This is
also the VLAN to which all source ports must be assigned.
vlan-id - MVR VLAN ID (Range: 1-4093)
