VLAN Configuration
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 let you 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 Next Entry button 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 First Entry button to
start over.
VLAN ID: The VLAN ID of the entry.
Snooping Enabled: Enable the per-VLAN IGMP Snooping. Up to 64 VLANs can be selected for IGMP Snooping.
Querier Election: Enable to join IGMP Querier election in the VLAN. Disable to act as an IGMP Non-Querier.
Querier Address: Define the IPv4 address as source address used in IP header for IGMP Querier election.
When the Querier address is not set, system uses IPv4 management address of the IP interface associated with
this VLAN. When the IPv4 management address is not set, system uses the first available IPv4 management
address. Otherwise, system uses a pre-defined value. By default, this value will be 192.0.2.1.
Compatibility: Compatibility is maintained by hosts and routers taking appropriate actions depending on the
versions of IGMP operating on hosts and routers within a network. The allowed selections are IGMP-Auto, Forced
IGMPv1, Forced IGMPv2, and Forced IGMPv3. The default compatibility value is IGMP-Auto.
PRI: Priority of Interface indicates the IGMP 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 PRI
value is 0.
RV: Robustness Variable allows tuning for the expected packet loss on a network. The allowed range is 1 to 255,
default RV value is 2.
QI (sec): Query Interval. The QI is the interval between General Queries sent by the Querier. The allowed range
is 1 to 31744 seconds; the default QI is 125 seconds.
QRI (0.1 sec): Query Response Interval is the Maximum Response Delay used to calculate the Maximum
Response Code inserted into the periodic General Queries. The allowed range is 0 to 31744 in tenths of a
second; the default QRI is 100 in tenths of a second (10 seconds).
LLQI (0.1 sec): (LMQI for IGMP): Last Member Query Interval is the time value represented by the LMQI,
multiplied by the Last Member Query Count. The allowed range is 0 to 31744 in tenths of a second; the default
LLQI is 10 in tenths of a second (1 second).
