Data
Use the Multicast > IGMP Snooping > Interface (Configure Interface) page to
configure an interface to drop IGMP query packets or multicast data packets.
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 RADIUS authentication when an IGMP Join
request is received. The switch will not learn the group report until the
authentication is successful. Further the authentication is valid for a one day
period so the same report will not need to be authenticated within that day.
Refer to the CLI Reference Guide for further information regarding IGMP
authentication.

1. Click Multicast, IGMP Snooping, Interface.
