Using delayed group flush

This feature continues to filter IGMP-Left groups for a specified additional time. Delay in flushing the group filter prevents stale traffic from being forwarded by the server. Delayed group flush is enabled or disabled for the entire switch.

Syntax:

igmp delayed-flush <time period>

Enables the switch to continue to flush IGMP-Left groups for a specified period of time (0 - 255 seconds). The default setting is Disabled. To disable, reset the time period to zero.

Syntax:

show igmp delayed-flush

Displays the current setting for the switch.
