Chapter 23 Multicast Figure 131 Advanced Application > Multicast > IPv6 Multicast > MLD Snooping-proxy > VLAN The following table describes the fields in the above screen. Table 77 Advanced Application > Multicast > IPv6 Multicast > MLD Snooping-proxy > VLAN LABEL VID Upstream Query Interval DESCRIPTION Enter the ID number of the VLAN on which you want to enable MLD snoopingproxy and configure related settings. Enter the amount of time (in miliseconds) between general query messages sent by the router connected to the upstream port. This value should be exactly the same as what's configured in the connected multicast router. This value is used to calculate the amount of time an MLD snooping membership entry (learned only on the upstream port) can remain in the forwarding table. Maximum Response Delay When an MLD Report message is received, the Switch sets the timeout period of the entry to be T = (QI*RV) + MRD, where T = Timeout, QI = Query Interval, RV = Robustness Variable, and MRD = Maximum Response Delay. Enter the amount of time (in miliseconds) the router connected to the upstream port waits for a response to an MLD general query message. This value should be exactly the same as what's configured in the connected multicast router. This value is used to calculate the amount of time an MLD snooping membership entry (learned only on the upstream port) can remain in the forwarding table. When an MLD Report message is received, the Switch sets the timeout period of the entry to be T = (QI*RV) + MRD, where T = Timeout, QI = Query Interval, RV = Robustness Variable, and MRD = Maximum Response Delay. When an MLD Done message is received, the Switch sets the entry's lifetime to be the product of Last Member Query Interval and Robustness Variable GS1920 Series User's Guide 177
