DGS-3130 Layer 3 Stackable Managed Switch CLI Reference Guide Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline The command is only available for VLAN interface configuration. The interface must have an IPv6 address assigned to start the querier. The system will return a warning message if the VLAN has no IPv6 address. If the querier is enabled, but the IPv6 address is removed, the querier will be stopped. If the system can play the querier role, the entity will listen for MLD query packets sent by other devices. If an MLD query message is received, the device with lower IPv6 address becomes the querier. If the MLD protocol is also enabled on the interface, the MLD snooping querier state will be disabled automatically. Example This example shows how to enable the MLD snooping querier state on VLAN 1. Switch# configure terminal Switch(config)# vlan 1 Switch(config-vlan)# ipv6 mld snooping querier Switch(config-vlan)# 52-11 ipv6 mld snooping query-interval This command is used to configure the interval at which the MLD snooping querier sends MLD general query messages. Use the no form of this command to revert to the default setting. ipv6 mld snooping query-interval SECONDS no ipv6 mld snooping query-interval Parameters SECONDS Specifies the interval at which the designated router sends MLD general query messages. The range is 1 to 31744. Default By default, this value is 125 seconds. Command Mode Interface Configuration Mode. Command Default Level Level: 12. Usage Guideline The command is only available for VLAN interface configuration. The query interval is the interval between general queries sent by the querier. By varying the query interval, an administrator may tune the number of MLD messages on the network. Larger values cause MLD Queries to be sent less often. 554
