DXS-3326GSR Gigabit Layer 3 Switch
Figure 7- 48. IGMP Interface Table window
To configure IGMP for a particular interface, click the corresponding hyperlink for that IP interface. This will open the
IGMP Interface Configuration window:
Figure 7- 49. IGMP Interface Configuration window
This window allows the configuration of IGMP for each IP interface configured on the Switch. IGMP can be configured as
Version 1 or 2 by toggling the Version field using the pull-down menu. The length of time between queries can be varied
by entering a value between 1 and 65,535 seconds in the Query Interval field. The maximum length of time between the
receipt of a query and the sending of an IGMP response report can be varied by entering a value in the Max Response Time
field.
The Robustness Variable field allows IGMP to be ‘tuned’ for sub-networks that are expected to lose a lot of packets. A
high value (max. 255) for the robustness variable will help compensate for ‘lossy’ sub-networks. A low value (min. 2)
should be used for less ‘lossy’ sub-networks.
The following fields can be set:
Parameter Description
Interface Name
<System>
Displays the name of the IP interface that is to be configured for IGMP. This must be a
previously configured IP interface.
IP Address
Displays the IP address corresponding to the IP interface name above.
Version <2> Enter the IGMP version (1 or 2) that will be used to interpret IGMP queries on the
interface.
Query Interval (1-
65535) <125>
Allows the entry of a value between 1 and 65535 seconds, with a default of 125
seconds. This specifies the length of time between sending IGMP queries.
