IGMP Interface Configuration
The Internet Group Multicasting Protocol (IGMP) can be configured on the Switch on a per-IP interface basis. To view the
IGMP Interface Table , open the IP Multicast Routing Protocol folder under Configuration and click IGMP Interface
Settings. Each IP interface configured on the Switch is displayed in the below IGMP Interface Table dialog box. To
configure IGMP for a particular interface, click the corresponding hyperlink for that IP interface. This will open another
IGMP Interface Configuration window:
Figure 6- 141. IGMP Interface Settings window
Figure 6- 142. IGMP Interface Settings - Edit window
This window allows the configuration of IGMP for each IP interface configured on the Switch. IGMP can be configured as
Version 1, 2 or 3 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 31,744 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 many 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 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.
