Figure 61 – Configuration > IGMP Snooping Configuration

By default, IGMP is disabled. If enabled, the IGMP Global Settings will need to be entered:

Host Timeout (130-153025 sec): This is the interval after which a learned host port entry will be purged. For

each host port learned, a 'Port Purge Timer' runs for 'Host Port Purge Interval'. This timer will be restarted

whenever a report message from host is received over that port. If no report messages are received for 'Host

Port Purge Interval' time, the learned host entry will be purged from the multicast group. The default value is

260 seconds.

Robustness Variable (2-255 sec): The Robustness Variable allows adjustment for the expected packet loss

on a subnet. If a subnet is expected to be lossy, the Robustness Variable may need to be increased. The

Robustness Variable cannot be set to zero, and it SHOULD NOT be. Default is 2 seconds.

Query Interval (60-600 sec): The Query Interval is the interval between General Queries sent. By adjusting

the Query Interval, the number of IGMP messages can be increased or decreased; larger values will cause

IGMP Queries to be sent less often. Default value is 125 seconds.

Router Timeout (60-600 sec): This is the interval after which a learned router port entry will be purged. For

each router port learned, a 'Router Port Purge Timer' runs for 'Router Port Purge Interval'. This timer will be

restarted whenever a Query control message is received over that port. If there are no Query control

messages received for 'Router Port Purge Interval' time, the learned router port entry will be purged. Default

is 260 seconds.

Last Member Query Interval (1-25 sec): The Last Member Query Interval is the Max Response Time

inserted into Group-Specific Queries sent in response to Leave Group messages, and is also the amount of

time between Group-Specific Query messages. This value may be adjusted to modify the "leave latency" of

the network. A reduced value results in reduced time to detect the loss of the last member of a group. Default

is 1 second.

Max Response Time (10-25 sec): The Max Response Time specifies the maximum allowed time before

sending a responding report message. Adjusting this setting effects the "leave latency", or the time between

the moment the last host leaves a group and when the multicast server is notified that there are no more

members. It also allows adjustments for controlling the frequency of IGMP traffic on a subnet. Default is 10

seconds.

Querier State: D-Link Smart Switch is able to send out the IGMP Queries to check the status of multicast

clients. Default is disabled.

To enable IGMP snooping for a given VLAN, select enable and click on the Apply button. Then press the

Edit button under Router Port Setting, and select the ports to be assigned as router ports for IGMP

snooping for the VLAN. Press Apply for changes to take effect. A router port configured manually is a Static

Router Port, and a Dynamic Router Port is dynamically configured by the Switch when a query control

message is received.
