(Optional) Configuring Report Message Suppression, Configuring Router Port Time and Member Port Time

Page 240 highlights

Configuring Layer 2 Multicast IGMP Snooping Configurations 1) Configure Unknown Multicast as Forward or Discard. Unknown Multicast 2) Click Apply. Configure the way how the switch processes the multicast data sent to unknown multicast groups as Forward or Discard. Unknown multicast groups are multicast groups whose destination multicast address is not in the multicast forwarding table of the switch. (Optional) Configuring Report Message Suppression Enabling Report Message Suppression can reduce the number of packets in the network. Follow these steps to configure report message suppression. 1) Enable or disable Report Message Suppression globally. Report Message Suppression If this function is enabled, the switch will only forward the first IGMP report message to Layer 3 devices and suppress subsequent IGMP report messages from the same multicast group during one query interval, which reduces the number of IGMP packets. 2) Click Apply. Configuring Router Port Time and Member Port Time Follow these steps to configure the aging time of the router ports and the member ports: 1) Specify the aging time of the router ports. Router Port Time Router ports are ports connected to Layer 3 devices on the switch. The router port ages if the switch does not receive IGMP query message from the router port within the router port time. The switch will no longer consider this port as a router port and delete it from the router port table. The valid values are from 60 to 600 seconds. 2) Specify the aging time of the member ports. Member Port Time 3) Click Apply. Member ports are ports connected to multicast group members on the switch. A port is considered to be a member port when it is added to a multicast group. The member port ages if the switch does not receive IGMP membership report message from the member port within the member port time. The switch will no longer consider this port as a member port and delete it from the multicast forwarding table. The valid values are from 60 to 600 seconds. Configuring IGMP Snooping Last Listener Query Configure the Last Listener Query Interval and Last Listener Query Count when the switch receives an IGMP leave message. If specified count of Multicast-Address-Specific Queries (MASQs) are sent and no report message is received, the switch will delete the multicast address from the multicast forwarding table.

Configuring Layer 2 Multicast
IGMP Snooping Configurations
Configuration Guide
219
1)
Configure Unknown Multicast as Forward or Discard.
Unknown
Multicast
Configure the way how the switch processes the multicast data sent to unknown
multicast groups as Forward or Discard. Unknown multicast groups are multicast
groups whose destination multicast address is not in the multicast forwarding
table of the switch.
2) Click
Apply
.
(Optional) Configuring Report Message Suppression
Enabling Report Message Suppression can reduce the number of packets in the network.
Follow these steps to configure report message suppression.
1)
Enable or disable Report Message Suppression globally.
Report Message
Suppression
If this function is enabled, the switch will only forward the first IGMP report
message to Layer 3 devices and suppress subsequent IGMP report messages
from the same multicast group during one query interval, which reduces the
number of IGMP packets.
2) Click
Apply
.
Configuring Router Port Time and Member Port Time
Follow these steps to configure the aging time of the router ports and the member ports:
1)
Specify the aging time of the router ports.
Router Port
Time
Router ports are ports connected to Layer 3 devices on the switch. The router
port ages if the switch does not receive IGMP query message from the router port
within the router port time. The switch will no longer consider this port as a router
port and delete it from the router port table. The valid values are from 60 to 600
seconds.
2)
Specify the aging time of the member ports.
Member Port
Time
Member ports are ports connected to multicast group members on the switch.
A port is considered to be a member port when it is added to a multicast group.
The member port ages if the switch does not receive IGMP membership report
message from the member port within the member port time. The switch will
no longer consider this port as a member port and delete it from the multicast
forwarding table. The valid values are from 60 to 600 seconds.
3) Click
Apply
.
Configuring IGMP Snooping Last Listener Query
Configure the Last Listener Query Interval and Last Listener Query Count when the switch
receives an IGMP leave message. If specified count of Multicast-Address-Specific Queries
(MASQs) are sent and no report message is received, the switch will delete the multicast
address from the multicast forwarding table.
