Configuring Multicast Mode

Using the CLI to Enable Multicast Mode

Follow these steps to enable multicast mode using the controller CLI.
To enable or disable multicasting on the controller, enter this command:
Step 1
config network multicast global {enable | disable}
The default value is disabled.
Note
Perform one of the following:
Step 2
a.
b.
To enable or disable IGMP snooping, enter this command:
Step 3
config network multicast igmp snooping {enable | disable}
The default value is disabled.
To set the IGMP timeout value, enter this command:
Step 4
config network multicast igmp timeout timeout
You can enter a timeout value between 30 and 300 seconds. The controller sends three queries in one
timeout value at an interval of timeout/3 to see if any clients exist for a particular multicast group. If the
controller does not receive a response through an IGMP report from the client, the controller times out
the client entry from the MGID table. When no clients are left for a particular multicast group, the
controller waits for the IGMP timeout value to expire and then deletes the MGID entry from the
controller. The controller always generates a general IGMP query (that is, to destination address
224.0.0.1) and sends it on all WLANs with an MGID value of 1.
Step 5 To save your changes, enter this command:

The config network broadcast {enable | disable} command allows you to enable or disable
broadcasting without enabling or disabling multicasting as well. This command uses the
multicast mode currently on the controller to operate.
To configure the controller to use the unicast method to send multicast packets, enter this command:
config network multicast mode unicast
To configure the controller to use the multicast method to send multicast packets to a CAPWAP
multicast group, enter this command:
config network multicast mode multicast multicast_group_ip_address
