GS108T and GS110TP Smart Switch Software Administration Manual • Host Timeout. Sets the value for group membership interval of IGMP snooping for the specified VLAN ID. The valid range is (Maximum Response Time + 1) to 3600 seconds. • Maximum Response Time. Enter the amount of time in seconds that a switch will wait after sending a query on the VLAN because it did not receive a report for a particular group in that interface. value. The valid range is 1 to 25 seconds. Its value must be less than the Host Timeout value. • MRouter Timeout. Enter the amount of time that a switch will wait to receive a query on the VLAN before removing it from the list of VLANs with multicast routers attached. Enter a value between 0 and 3600 seconds. The default is 0 seconds, which means there is no expiration. • Query Mode. Enable or disable the IGMP Querier Mode for the specified VLAN ID. • Query Interval. Enter the value for IGMP Query Interval for the specified VLAN ID. The valid range is 1-1800 seconds. The default is 60 seconds. 2. Click Cancel to cancel the configuration on the screen and reset the data on the screen to the latest value of the switch. 3. To disable IGMP snooping on a VLAN and remove it from the list, select the check box next to the VLAN ID and click Delete. 4. To modify IGMP snooping settings for a VLAN, select the check box next to the VLAN ID, update the desired values, and click Apply. 5. Click Cancel to cancel the configuration on the screen and reset the data on the screen to the latest value of the switch. IGMP Snooping Querier IGMP snooping requires that one central switch or router periodically query all end-devices on the network to announce their multicast memberships. This central device is the IGMP querier. The IGMP query responses, known as IGMP reports, keep the switch updated with the current multicast group membership on a port-by-port basis. If the switch does not receive updated membership information in a timely fashion, it will stop forwarding multicasts to the port where the end device is located. These pages enable you to configure and display information on IGMP snooping queriers on the network and, separately, on VLANs. The IGMP Snooping Querier feature contains links to the following pages: • "IGMP Snooping Querier Configuration" on page 3-50 • "IGMP Snooping Querier VLAN Configuration" on page 3-51 • "IGMP Snooping Querier VLAN Status" on page 3-52 Configuring Switching Information v1.0, April 2010 3-49

IGMP Snooping Querier

IGMP snooping requires that one central switch or router periodically query all end-devices on the

network to announce their multicast memberships. This central device is the IGMP querier. The

IGMP query responses, known as IGMP reports, keep the switch updated with the current

multicast group membership on a port-by-port basis. If the switch does not receive updated

membership information in a timely fashion, it will stop forwarding multicasts to the port where

the end device is located.

These pages enable you to configure and display information on IGMP snooping queriers on the

network and, separately, on VLANs.
