xStack® DGS-3620 Series Layer 3 Managed Stackable Gigabit Switch CLI Reference Guide decides that there is no longer another multicast router that is the querier. This interval is calculated as follows: (robustness variable x query interval) + (0.5 x query response interval). 3. Last member query count-Number of group-specific queries sent before the router assumes there are no local members of a group. The default number is the value of the robustness variable. - Specify the value between 1 and 7. Increase the value if you expect a subnet to be lossy. The robustness variable is set to 2 by default. last_member_query_interval - Specify the maximum amount of time between group-specific query messages, including those sent in response to leave-group messages. You might lower this interval to reduce the amount of time it takes a router to detect the loss of the last member of a group. - Specify the time between 1 and 25 seconds. state - This allows the switch to be specified as an MLD Querier (sends MLD query packets) or a Non-Querier (does not send MLD query packets). Set to enable or disable. enable - Allows the switch to be selected as an MLD Querier (sends MLD query packets). disable - When disabled, the switch can not play the role as a querier. version - Specify the version of MLD packet that will be sent by this port. If a MLD packet received by the interface has a version higher than the specified version, this packet will be forward from router ports or VLAN flooding. - Specify the values between 1 and 2. Restrictions Only Administrator, Operator and Power-User level users can issue this command. Example To configure the MLD snooping querier: DGS-3620-28SC:admin#config mld_snooping querier vlan_name default query_interval 125 state enable Command: config mld_snooping querier vlan_name default query_interval 125 state enable Success. DGS-3620-28SC:admin# 61-11 config mld_snooping mrouter_ports Description This command allows users to designate a range of ports as being connected to multicast-enabled routers. This will ensure that all packets with such a router as its destination will reach the multicast-enabled router, regardless of protocol. Format config mld_snooping mrouter_ports [vlan | vlanid ] [add | delete] Parameters vlan - Specify the name of the VLAN on which the router port resides. 678
