Usage Guidelines Configure a port as a source port if that port should be able to both send and receive multicast data bound
for the configured multicast groups. Multicast data is received on all ports configured as source ports.
Configure a port as a receiver port if that port should only be able to receive multicast data and should
not be able to send multicast data to the configured multicast groups. None of the receiver ports receives
multicast data unless it sends an Internet Group Management Protocol (IGMP) group join message for
a multicast group.
A receiver port configured as a static member of a multicast group remains a member until statically
removed from membership.
Note All receiver ports must not be trunk ports and must not belong to the MVR source VLAN.
A port that is not taking part in MVR should not be configured as an MVR receiver port or source port.
This port is a normal switch port and is able to send and receive multicast data with normal switch
behavior.
Examples This example shows how to configure a port as an MVR receiver port:
Switch(config)# interface fastethernet0/1
Switch(config-if)# mvr type receiver
OL-10102-01
mvr type {receiver | source}

Port that receives multicast data and cannot send multicast data to multicast
