Configuring IGMP Snooping
127
Perform the following configuration in System View and VLAN View.
Although layer 2 and layer 3 multicast protocols can run together, they cannot run
on the same VLAN or its corresponding VLAN interface at the same time. For
example, if the layer 2 multicast protocol is enabled on a VLAN, then the layer 3
multicast protocol cannot operate on this VLAN, and vice versa.
IGMP Snooping functions only when it is enabled both in System View and in
VLAN View.
By default, IGMP Snooping is disabled.
Configuring Router Port
Aging Time
Use the commands in
Table 130
to manually configure the router port aging time.
If the switch has not received a general query message from the router before the
router port is aged, the switch will remove the port from the MAC multicast
group.
Perform the following configuration in system view.
By default, the port aging time is 105 seconds.
Configuring Maximum
Response Time
Use the commands in
Table 131
to manually configure the maximum response
time. If the Switch 4500 receives no report message from a port within the
maximum response time, the switch will remove the port from the multicast
group.
Perform the following configuration in System View.
By default, the maximum response time is 10 seconds.
Configuring Aging Time
of Multicast Group
Member
Use the commands in
Table 132
to manually set 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 start a maximum response timer.
