(Optional) Discarding IGMP Query Messages Sent form Users

(Optional) Discarding IGMP Query Messages Sent form Users

Context

By default, the Switch discards IGMP Query messages sent from users in a VLAN after MFF is enabled in the VLAN. If IGMP snooping is also enabled in the VLAN, the Switch still processes IGMP Query messages sent from users because IGMP snooping takes precedence over MFF. IGMP Query messages are then broadcast in the VLAN and forwarded to network-side devices. This affects IGMP querier election on the upstream devices and causes multicast service failures.

In this scenario, configure the Switch to discard IGMP Query messages sent from users.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run vlan vlan-id

    The VLAN view is displayed.

  3. Run mac-forced-forwarding igmp-query discard

    The Switch is configured to discard IGMP Query messages sent form users.

    By default, the Switch does not discard IGMP Query messages from users when both MFF and IGMP snooping are enabled in a VLAN.
