Figure 4-6-57 IGMP Interface Configuration
Selection Criteria
o Slot/Port - Select the slot and port for which data is to be displayed or configured from the pulldown menu. Slot 0 is
the base unit. You must have configured at least one router interface before configuring or displaying data for an
IGMP interface, otherwise an error message will be displayed.
Configurable Data
o Interface Mode - Select enable or disable from the pulldown menu to set the administrative status of IGMP on the
selected interface. The default is disable.
o Version - Enter the version of IGMP you want to configure on the selected interface. Valid values are 1 to 2 and the
default value is 2.
o Robustness - Enter the robustness value. This variable allows tuning for the expected packet loss on a subnet. If
you expect the subnet to be lossy, you should enter a higher number for this parameter. IGMP is robust to
(robustness variable-1) packet losses. Valid values are from 1 to 255. The default value is 2.
o Query Interval - Enter the frequency in seconds at which IGMP host-query packets are to be transmitted on this
interface. Valid values are from 1 to 3600. The default value is 125.
