configure eaps multicast send-igmp-query

configure eaps multicast send-igmp-query [on | off]

Description

Configures the switch to send IGMP (Internet Group Management Protocol) query messages to all protected VLAN (Virtual LAN)s when an EAPS (Extreme Automatic Protection Switching) topology change occurs.

Syntax Description

on	Enables the multicast send-igmp-query feature.
off	Disables the multicast send-igmp-query feature.

Default

On.

Usage Guidelines

When this feature is set to on and an EAPS topology change occurs, the switch sends IGMP query messages to all protected VLANs. If the protected VLANs in the node detecting (and generating) the topology change do not have IP address, a query is generated with the source IP address set to the querier address in that VLAN.

In a EAPS ring with many protected VLANs, the many responses can impact switch performance. This is the default behavior and was the only method for supporting multicast traffic during EAPS topology changes prior to release 12.1.2.

When this feature is set to off and an EAPS topology change occurs, the switch does not automatically send IGMP queries to all protected VLANS during the topology transition. The off setting improves switch performance during the transition, but you should use one of the following commands to see that multicast traffic is supported during and after the topology change:

Example

The following command disables the send-igmp-query feature:

configure eaps multicast send-igmp-query off

History

This command was first available in ExtremeXOS 12.1.2.

Platform Availability

This command is available on the Summit X450-G2, X460-G2, X670-G2, X770, and ExtremeSwitching X440-G2, X620, X690, X870 series switches.
