Configuring a Policy to Filter IGMP Report/Leave Messages

Configuring a Policy to Filter IGMP Report/Leave Messages

Context

You can configure a policy to filter IGMP Report/Leave messages from specified hosts to improve security of multicast services.

This function must be used together with an access control list (ACL). When a basic ACL is used, IGMP Report/Leave messages with specified source addresses can be filtered. When an advanced ACL is used, IGMP Report/Leave messages with destination addresses or source addresses can be filtered. For details on how to configure an ACL, see "ACL Configuration" in the CloudEngine 8800, 7800, 6800, and 5800 Series Switches Configuration Guide - Security.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run vlan vlan-id

    The VLAN view is displayed.

  3. Run igmp snooping ip-source-policy { acl-number | acl-name acl-name }

    A policy is configured to filter IGMP Report/Leave messages so that hosts in the VLAN can only dynamically join multicast groups matching the ACL.

    By default, no policy is configured to filter IGMP Report/Leave messages in a VLAN.

  4. Run commit

    The configuration is committed.
