Multicast Filtering Commands
4-263
4
IGMPv1/v2 multicast report messages or IGMPv2 leave messages sent by
IGMPv1/v2 hosts are supported by the current MVR standard.
• IGMP snooping and MVR share a maximum number of 255 groups. Any
multicast streams received in excess of this limitation will be flooded to all
ports in the associated VLAN.
Example
The following example enables MVR globally, designates the MVR VLAN as VLAN
1, and configures a range of MVR group addresses:
mvr (Interface Configuration)
This command configures an interface as a static member of an MVR group using
the
group keyword, or configures an interface as an MVR receiver or source port
using the type keyword. Use the no form to restore the default settings.
Syntax
[ no ] mvr { group ip-address | type { receiver | source }}
• ip-address - Statically configures an interface to receive multicast traffic
from the IP address specified for an MVR multicast group.
(Range: 224.0.1.0 - 239.255.255.255)
• receiver - Configures the interface as a subscriber port that can receive
multicast data.
• source - Configure the interface as an uplink port that can send and receive
multicast data for the configured multicast groups.
Default Setting
• The port type is not defined.
• No port is a member of any configured multicast group.
Command Mode
Interface Configuration (Ethernet, Port Channel)
Command Usage
• A port which is not configured as an MVR receiver or source port can use
IGMP snooping to join or leave multicast groups using the standard rules for
multicast filtering.
• Receiver ports can belong to different VLANs. IGMP snooping can be used
to allow a receiver port to dynamically join or leave multicast groups within an
MVR VLAN. Multicast groups can also be statically assigned to a receiver port
using the
group keyword. However, if a receiver port is statically configured
as a member of an MVR VLAN, its status will be inactive. Also, note that VLAN
membership for MVR receiver ports cannot be set to trunk mode (see the
switchport mode command on page 4-197).
