configure eaps multicast add-ring-ports

configure eaps multicast add-ring-ports [on | off]

Description

Configures the switch to add previously blocked ring ports to existing multicast groups when an EAPS topology change occurs.

Syntax Description


on	Enables the multicast add-ring-ports feature.
off	Disables the multicast add-ring-ports feature.

Default

Off.

Usage Guidelines

When this feature is set to on and an EAPS topology change occurs, multicast traffic is fastpath forwarded using the switch hardware during the topology transition. The on setting improves multicast forwarding performance during the transition.

Note

EAPS multicast flooding must be enabled before this feature will operate. For information on enabling EAPS multicast flooding, see the configure eaps multicast temporary-flooding command description.

When this feature is set to off and an EAPS topology change occurs, multicast traffic is slowpath forwarded using the CPU during the topology transition. The off setting reduces multicast forwarding performance during the transition.

For other methods of supporting multicast traffic during an EAPS topology change, see the descriptions for the following commands:

Example

The following example enables the add-ring-ports feature:

configure eaps multicast add-ring-ports on
