DGS-1510 Series Gigabit Ethernet SmartPro Switch CLI Reference Guide
Switch# configure terminal
Switch(config)# vlan 1
Switch(config-vlan)# ip igmp snooping fast-leave
Switch(config-vlan)#
33-4 ip igmp snooping last-member-query-interval
This command is used to configure the interval at which the IGMP snooping querier sends IGMP
group-specific or group-source-specific (channel) query messages. Use the no form of this command
to revert to the default setting.
ip igmp snooping last-member-query-interval SECONDS
no ip igmp snooping last-member-query-interval
Parameters
SECONDS
Default
By default, this value is 1 second.
Command Mode
Interface Configuration Mode.
Command Default Level
Level: 12.
Usage Guideline
The command is only available for VLAN interface configuration. On receiving an IGMP leave
message, the IGMP snooping querier will assume that there are no local members on the interface if
there are no reports received after the response time. Users can lower this interval to reduce the
amount of time it takes a switch to detect the loss of the last member of a group.
Example
This example shows how to configure the last member query interval time to be 3 seconds.
Switch# configure terminal
Switch(config)# vlan 1000
Switch(config-vlan)# ip igmp snooping last-member-query-interval 3
Switch(config-vlan)#
33-5 ip igmp snooping mrouter
This command is used to configure the specified interface(s) as the multicast router ports or as
forbidden to be multicast router ports on the Switch. Use the no form of this command to remove the
interface(s) from router ports or forbidden multicast router ports.
ip igmp snooping mrouter {interface INTERFACE-ID [,|-] | forbidden interface INTERFACE-ID
[,|-]}
no ip igmp snooping mrouter {interface INTERFACE-ID [,|-] | forbidden interface
INTERFACE-ID [,|-]}
Specifies the maximum amount of time between group-specific
query messages, including those sent in response to leave-group
messages. The range of this value is 1 to 25.
