Switch 7700 Configuration Guide

120 CHAPTER 6: MULTICAST PROTOCOL
Perform the following configuration in system view.
By default, the maximum response time is 10 seconds.
Configure Aging Time of Multicast Group Member
This task sets the aging time of the multicast group member port. If the switch
receives no multicast group report message during the member port aging time, it
will transmit the specific query message to that port and starts a maximum
response timer.
Perform the following configuration in system view.
By default, the aging time of the multicast member is 260 seconds.
Display and debug IGMP
Snooping
After the above configuration, execute the display command in all views to
display the running of the IGMP Snooping configuration, and to verify the effect
of the configuration. Execute the debugging command in user view to debug
IGMP Snooping configuration.
IGMP Snooping
Configuration Example
To implement IGMP Snooping on the switch, first enable it. The switch is
connected with the router via the router port, and with user PC through the
non-router ports.
