4.17.5 MLD Snooping VLAN Configuration

Navigating the MLD Snooping VLAN Table

Each page shows up to 99 entries from the VLAN table, default being 20, selected through the "entries per page" input field. When first visited, the web page will show the first 20 entries from the beginning of the VLAN Table. The first displayed will be the one with the lowest VLAN ID found in the VLAN Table. The "VLAN" input fields allow the user to select the starting point in the VLAN Table. Clicking the Refresh button will update the displayed table starting from that or the next closest VLAN Table match. The >> will use the last entry of the currently displayed entry as a basis for the next lookup. When the end is reached the text "No more entries" is shown in the displayed table. Use the |<< button to start over.

Note: For MLD VLAN interface creation, you need to enter IP configuration page to setup IP interface first. System -> IP -> Add IP interface.
  • VLAN ID: The VLAN ID of the entry.
  • MLD Snooping Enabled: Enable the per-VLAN MLD Snooping. Up to 8 VLANs can be selected for MLD Snooping.
  • Querier Election: Enable to join MLD Querier election in the VLAN. Disable to act as an MLD Non-Querier.
  • Compatibility: Compatibility is maintained by hosts and routers taking appropriate actions depending on the versions of MLD operating on hosts and routers within a network. The allowed selection is MLD-Auto, Forced MLDv1, Forced MLDv2, default compatibility value is MLD-Auto.
  • Priority of Interface (PRI): Indicates the MLD control frame priority level generated by the system. These values can be used to prioritize different classes of traffic. The allowed range is 0 (best effort) to 7 (highest), default interface priority value is 0.
  • Robustness Variable (RV): The Robustness Variable allows tuning for the expected packet loss on a network. The allowed range is 2-255, default robustness variable value is 2.
  • Query Interval (QI): The Query Interval is the interval between General Queries sent by the Querier. The allowed range is 1-31744 seconds, default query interval is 125 seconds.
  • Query Response Interval (QRI): The Maximum Response Delay used to calculate the Maximum Response Code inserted into the periodic General Queries. Allowed range is 0-31744 in tenths of seconds, default query response interval is 100 in tenths of seconds (10 seconds).
  • Last Listener Query Interval (LLQI): The Last Listener Query Interval is the Maximum Response Delay used to calculate the Maximum Response Code inserted into Multicast Address Specific Queries sent in response to Version 1 Multicast Listener Done messages. It is also the Maximum Response Delay used to calculate the Maximum Response Code inserted into Multicast Address and Source Specific Query messages. The allowed range is 0-31744 in tenths of seconds, default last listener query interval is 10 in tenths of seconds (1 second).
  • Unsolicited Report Interval (URI): The Unsolicited Report Interval is the time between repetitions of a node's initial report of interest in a multicast address. The allowed range is 0-31744 seconds, default unsolicited report interval is 1 second.
