Accton Technology VDSL Switch-VS4512, Management Manual, Page: 310 / 334

Command Line Interface
4-164
Command Usage
• The switch must be using IGMPv2 for this command to take effect.
• This command defines the time after a query, during which a response is
expected from a multicast client. If a querier has sent a number of queries
defined by the
ip igmp snooping query-count , but a client has not responded,
a countdown timer is started using an initial value set by this command. If the
countdown finishes, and the client still has not responded, then that client is
considered to have left the multicast group.
Example
The following shows how to configure the maximum response time to 20 seconds:
