4.2.3 Configuring MVR for the Ports
Follow these steps to configure MVR for the ports:
Step 1 configure
Enter global configuration mode.
Step 2 interface {fastEthernet
port
| range fastEthernet
port-list
| gigabitEthernet
port
| range
gigabitEthernet
port-list
| ten-gigabitEthernet
port
| range ten-gigabitEthernet
port-list
}
Enter interface configuration mode.
Step 3 mvr
Enable MVR for the port.
Step 4 mvr type { source | receiver }
Configure the MVR port type as receiver or source. By default, the port is a non-MVR port. If
you attempt to configure a non-MVR port with MVR characteristics, the operation fails.
source: Configure the uplink ports that receive and send multicast data on the multicast VLAN
as source ports. Source ports should belong to the multicast VLAN.
receiver: Configure the ports that are connecting to the hosts as receiver ports. A receiver
port can only belong to one VLAN, and cannot belong to the multicast VLAN.
Step 5 mvr immediate
(Optional) Enable the Fast Leave feature of MVR for the port. Only receiver ports support Fast
Leave. Before enabling Fast Leave for a port, make sure there is only a single receiver device
connecting to the port.
Step 6 mvr vlan
vlan-id
group
ip-addr
(Optional) Statically add the port to an MVR group. Then the port can receive multicast traffic
sent to the IP multicast address via the multicast VLAN.
This command applies to only receiver ports. The switch adds or removes the receiver ports
to the corresponding multicast groups by snooping the report and leave messages from the
hosts. You can also statically add a receiver port to an MVR group.
vlan-id
: Enter the multicast VLAN ID.
ip-addr
: Specify the IP address of the multicast group.
