The Internet Group Management Protocol (IGMP) pruning screen has two options:
IGMP pruning
Either enabled or disabled
Pruning timeout
(250-10000 sec) The default is 250 sec.
Note
The IGMP pruning timer is triggered when an IGMP packet is received on the VLAN. A 510T
switch must have a 550 series device with IP Multicast enabled in the same VLAN to trigger
the timer.
