IGMP/VLAN Configuration Screen
Layer 3 Extensions Menu Screens 10-5
Field Descriptions
Table 10-2 describes each field of the IGMP/VLAN Configuration screen:
Table 10-2 IGMP/VLAN Configuration Screen Field Descriptions
Use this field… To…
IGMP Version
(Toggle)
See the current configured IGMP version running on the VLAN
selected in the VLAN ID field (version 1 or 2). The default is version 2.
The IGMP Version field can be toggled to configure the switch in
either version 1 or 2 to match the router configuration. For IGMP to
function correctly, all switches on a LAN must be configured to run the
same version of IGMP. All VLANs available to the switch will be
affected if ALL is chosen as the option under VLAN ID. The field will
initially display an asterisk (*).
Query Interval
(Modifiable)
See or change the query interval time. If the switch is the querier, the
value in the Query Interval field indicates how often IGMP Host-Query
frames are transmitted on the VLAN selected in the VLAN ID field.
This value is also used in calculations for other timers. The default
value is 125 seconds. The range of possible entries is 1 to 300 seconds.
An entry outside of the range will cause the error message
“PERMISSIBLE RANGE: 1...300” to display in the Event Message
field. The field will initially display an asterisk (*).
Query Response
Time
(Modifiable)
Enter the maximum query response time advertised in IGMPv2 general
queries on this VLAN. This value is used in calculations for other
timers. The default value is 10 seconds. The range of possible entries is
1 to 300 seconds. The value entered in this field cannot be bigger than
the Query Interval. The field will initially display an asterisk (*).
Interface
Robustness
(Modifiable)
Tune the expected frame loss on a subnet. If a subnet is expected to be
high loss, the Robustness Variable may be increased. IGMP is robust to
(Robustness Variable-1) packet losses. This value is also used in
calculations for other timers. The default value is 2. The field will
initially display an asterisk (*).
TIP: If the Interface Robustness is adjusted higher than the
default value, depending on the network, this may be an
indication of problems with the network that need to be
resolved.
