2.2.3 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 within the maximum response time, it will
remove the port from the multicast group.
Perform the following configuration in system view.
Table 2-3 Configuring the maximum response time
Configure the maximum response
time
Restore the default setting
By default, the maximum response time is 1 seconds.

2.2.4 Configuring Aging Time of Multicast Group Member Ports

This task is to manually set the aging time of the multicast group member port. If the
Ethernet 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.
Table 2-4 Configuring aging time of the multicast member ports

multicast member

By default, the aging time of the multicast member is 260 seconds.
2.2.5 Configuring Unknown Multicast Packets not Broadcasted within a
VLAN
This configuration task is to enable/disable the function of not broadcasting unknown
multicast packets within a VLAN. If this function is disabled but IGMP snooping enabled
on VLAN, multicast packets are broadcasted on within the VLAN when the destination
broadcast group has no member ports. When this function is enabled, however,
multicast packets are only forwarded to the router port, but not broadcasted within the
VLAN if no member port exists. In addition, since the router sends regularly IGMP
Query and PIM Hello packets, the switch can identify which ports are router ports. If
