Filtering IGMP Packets
on an Interface
Use the Multicast > IGMP Snooping > Interface (Configure Interface) page to
configure an interface to drop IGMP query packets or multicast data packets, or
enable IGMP authentication.
Parameters
These parameters are displayed:
Interface – Port or Trunk identifier.
IGMP Query Drop – Configures an interface to drop any IGMP query packets
received on the specified interface. If this switch is acting as a Querier, this
prevents it from being affected by messages received from another Querier.
Multicast Data Drop – Configures an interface to stop multicast services from
being forwarded to users attached to the downstream port (i.e., the interfaces
specified by this command).
IGMP Authentication – Enables IGMP authentication on the specified
interface. When enabled and an IGMP JOIN request is received, an
authentication request is sent to a configured RADIUS server.
Web Interface
To drop IGMP query packets or multicast data packets:
1. Click Multicast, IGMP Snooping, Interface.
2. Select Configure Interface from the Action list.
3. Select Port or Trunk interface.
4. Enable the required drop functions for any interface.
