Chapter14 Configuring IGMP Snooping and MVR
Configuring MVR
You can use the show mvr members privileged EXEC command to verify the MVR multicast group
addresses on the switch.
Configuring MVR Interfaces
Beginning in privileged EXEC mode, follow these steps to configure MVR interfaces:
To return the interface to its default settings, use the no mvr [type | immediate | vlan vlan-id | group]
interface configuration commands.
Command Purpose
Step1 configure terminal Enter global configuration mode.
Step2 mvr Enable MVR on the switch.
Step3 interface interface-id Enter the port to configure and enter interface configuration mode.
Step4 mvr type {source | receiver} Configure an MVR port as one of these:
•source—Configure uplink ports that receive and send multicast data as
source ports. Subscribers cannot be directly connected to source ports.
All source ports on a switch belong to the single multicast VLAN.
•receiver—Configure a port as a receiver port if it is a subscriber port and
should only receive multicast data. It does not receive data unless it
becomes a member of the multicast group, either statically or by using
IGMP leave and join messages. Receiver ports cannot belong to the
multicast VLAN.
The default configuration is as a non-MVR port. If you attempt to configure
a non-MVR port with MVR characteristics, the operation fails.
Step5 mvr vlan vlan-id group ip-address (Optional) Statically configure a port to receive multicast traffic sent to the
multicast VLAN and the IP multicast address. A port statically configured as
a member of a group remains a member of the group until statically removed.
Note In compatible mode, this command applies to only receiver ports. In
dynamic mode, it applies to receiver ports and source ports.
Receiver ports can also dynamically join multicast groups by using IGMP
join and leave messages.
Step6 mvr immediate (Optional) Enable the Immediate Leave feature of MVR on the port.
Note This command applies to only receiver ports and should only be
enabled on receiver ports to which a single receiver device is
connected.
Step7 end Return to privileged EXEC mode.
Step8 show mvr
show mvr interface
or
show mvr members
Verify the configuration.
Step9 copy running-config startup-config (Optional) Save your entries in the configuration file.
