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.
