Configuring Router Port Aging Time; Configuring Maximum Response Time - 3Com 8800 Configuration Manual

3Com Switch 8800 Configuration Guide
Table 24-1 Enabling/Disabling IGMP Snooping
Enable/disable IGMP Snooping
By default, IGMP Snooping is disabled.
Caution:
Although layer 2 and layer 3 multicast protocols can be configured in pair, they
cannot run on the same VLAN or its corresponding VLAN interface at the same time.
For example, if PIM or IGMP is enabled on a VLAN, then IGMP Snooping cannot
operate on this VLAN.
IGMP Snooping functions only when it is enabled both in system view and in VLAN
view. Otherwise, IGMP Snooping does not take effect.

24.2.2 Configuring Router Port Aging Time

This task is to manually configure the router port aging time. If the switch has not
received any general query message from the router before the router port is aged, it
will remove the port from all MAC multicast groups.
Perform the following configuration in system view.

Configure router port aging time
Restore the default aging time
By default, the port aging time is 105s.

24.2.3 Configuring Maximum Response Time

This task is to manually configure the maximum response time. If the Ethernet switch
receives no report message from a port in the maximum response time, it will remove
the port from the multicast group.
Perform the following configuration in system view.
