Enabling Mesh Multicast Containment for Video
You can use the controller CLI to configure three mesh multicast modes to manage video camera broadcasts
on all mesh access points. When enabled, these modes reduce unnecessary multicast transmissions within the
mesh network and conserve backhaul bandwidth.
Mesh multicast modes determine how bridging-enabled access points MAP and RAP send multicasts among
Ethernet LANs within a mesh network. Mesh multicast modes manage non-CAPWAP multicast traffic only.
CAPWAP multicast traffic is governed by a different mechanism.
The three mesh multicast modes are as follows:
• Regular mode—Data is multicast across the entire mesh network and all its segments by bridging-enabled
• In-only mode—Multicast packets received from the Ethernet by a MAP are forwarded to the RAP's
• In-out mode—The RAP and MAP both multicast but in a different manner:

Ethernet network. No additional forwarding occurs, which ensures that non-CAPWAP multicasts received
by the RAP are not sent back to the MAP Ethernet networks within the mesh network (their point of
origin), and MAP to MAP multicasts do not occur because they are filtered out.

Note
In-Out multicast mode be configured.
◦ In-out mode is the default mode.
◦ If multicast packets are received at a MAP over Ethernet, they are sent to the RAP; however, they
are not sent to other MAP over Ethernet, and the MAP to MAP packets are filtered out of the
multicast.
◦ If multicast packets are received at a RAP over Ethernet, they are sent to all the MAPs and their
respective Ethernet networks. When the in-out mode is in operation, it is important to properly
