Configuring Mobility Multicast
In the WebUI
To configure the mobility multicast feature using the controller WebUI:
1. Navigate to the Configuration > Network > IP window.
2. Click Edit by the VLAN interface for which you want to configure mobility multicast. The Edit VLAN window
opens.
3. Select Enable IGMP to enable the router to discover the presence of multicast listeners on directly-attached
links.
4. Select Snooping to save bandwidth and limit the sending of multicast frames to only those nodes that
need to receive them.
5. 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.
6. Click Apply.
7. (Optional) Repeat steps 1-6 above to configure mobility multicast for another VLAN interface.
In 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]
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>
<slot>/<module>/<port>
(W-7200only)
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>.
<slot> is always 1, except when referring to interfaces on the W-6000
controller(slots 0-3).
The <port> parameter refers to the network interfaces that are embedded
in the front panel of the W-3000 Series controller, or a W-6000M3
controller module. Port numbers start at 0 from the left-most position.
The W-7200 Series controllers use a <slot>/<module>/<port> port num-
bering scheme. <slot> and <module> will always be 0 on the W-7200 Ser-
ies.
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.
Table 118: Command Syntax
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
