Configuring Multicast Mode
•
For LWAPP, the controller drops multicast packets sent to UDP control port 12223. For CAPWAP,
the controller drops multicast packets sent to UDP control and data ports 5246 and 5247,
respectively. Therefore, you may want to consider not using these port numbers with the multicast
applications on your network.
•
Cisco recommends that any multicast applications on your network not use the multicast address
configured as the CAPWAP multicast group address on the controller.
•
2100 series controllers do not support multicast-unicast mode. They do, however, support
multicast-multicast mode, except when access points are connected directly to the local port of a
2100 series controller.
Using the GUI to Enable Multicast Mode
Follow these steps to enable multicast mode using the controller GUI.
Step 1
Click
Controller
to open the General page (see
Figure 4-10
General Page
Step 2
Choose one of the following options from the Ethernet Multicast Mode drop-down box:
•
Disabled
—Disables multicasting on the controller. This is the default value.
•
Unicast
—Configures the controller to use the unicast method to send multicast packets.
•
Multicast
—Configures the controller to use the multicast method to send multicast packets to a
CAPWAP multicast group.
Note
Hybrid REAP supports unicast mode only.
Step 3
If you chose Multicast in
, enter the IP address of the multicast group in the Multicast Group
Address field.
