local controller leaves the group, it will also notify remote controller A.) If either controller has other clients
using that group, that controller it will continue its group1 membership.
Configuring Mobility Multicast Using the WebUI
To configure the mobility multicast feature using the controller WebUI:
1. Navigate to the Configuration > Network > IP window. Click the Edit button by the VLAN interface for
which you want to configure mobility multicast. The Edit VLAN window opens.
2. Select Enable IGMP to enable the router to discover the presence of multicast listeners on directly-attached
links.
3. Select Snooping to save bandwidth and limit the sending of multicast frames to only those nodes that need to
receive them.
4. Select the Interface checkbox, then click the Proxy drop-down list and select the controller interface, port and
slot for which you want to enable proxy IGMP.
5. Click Apply to apply your changes.
(Optional) Repeat steps 1-6 above to configure mobility multicast for another VLAN interface.
Configuring Mobility Multicast Using the CLI
The following command enables IGMP and/or IGMP snooping on this interface, or configures a VLAN interface
for uninterrupted streaming of multicast traffic.
interface vlan <vlan>
ip igmp proxy [{fastethernet|gigabitethernet} <slot>/<port>]|[snooping]
Example
The following example configures IGMP proxy for vlan 2. IGMP reports from the controller would be sent to the
upstream router on fastethernet port 1/3.
conf# interface vlan 2
conf-subif# ip igmp proxy fastethernet 1/3
Table 81 Command Syntax
Parameter Description
fastethernet Enable IGMP proxy on the FastEthernet (IEEE 802.3) interface
gigabitethernet Enable IGMP proxy on the GigabitEthernet (IEEE 802.3) interface
<slot>/<port> Any command that references a Fast Ethernet or Gigabit Ethernet interface requires that you specify
the corresponding port on the controller in the format <slot>/<port>.
snooping Enable IGMP snooping.
The IGMP protocol enables an router to discover the presence of multicast listeners on directly-
attached links. Enable IGMP snooping to limit the sending of multicast frames to only those nodes that
need to receive them.
