ProSafe® Gigabit L3 Managed Stackable Switches Software Administration Manual 1. Interface - The interface for which data is to be displayed or configured. 2. Use Admin Mode to set the administrative status of IGMP on the selected interface. The default is disable. 3. Use Version to enter the version of IGMP you want to configure on the selected interface. Valid values are (1 to 3) and the default value is 3. This field is configurable only when IGMP interface mode is enabled. 4. Use Robustness to 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. 5. Use Query Interval to enter the frequency in seconds at which IGMP host-query packets are to be transmitted on this interface. Valid values are from 1 to 1800. The default value is 125. 6. Use Query Max Response Time to enter the maximum query response time to be advertised in IGMPv2 queries on this interface, in tenths of a second. The default value is 100. Valid values are from(0 to 255). 7. Use Startup Query Interval to enter the number of seconds between the transmission of startup queries on the selected interface. The valid values are from 1 to 300. The default value is 31. 8. Use Startup Query Count to enter the number of queries to be sent on startup. The valid values are from 1 to 20. The default value is 2. 9. Use Last Member Query Interval to enter the last member query interval in tenths of a second. This the maximum response time to be inserted into group-specific queries sent in response to leave group messages, and is also the amount of time between group-specific query messages. Valid values are from 0 to 255. The default value is 10. This value is not used for IGMP version 1. 10. Use Last Member Query Count to enter the number of queries to be sent on receiving a leave group report. Valid values are from 1 to 20. The default value is 2. 348 | Chapter 4. Routing

1.
Interface
- The interface for which data is to be displayed or configured.
2.
Use
Admin Mode
to set the administrative status of IGMP on the selected interface. The
default is disable.
3.
Use
Version
to enter the version of IGMP you want to configure on the selected interface.
Valid values are (1 to 3) and the default value is 3. This field is configurable only when IGMP
interface mode is enabled.
4.
Use
Robustness
to 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.
5.
Use
Query Interval
to enter the frequency in seconds at which IGMP host-query packets
are to be transmitted on this interface. Valid values are from 1 to 1800. The default value is
125.
6.
Use
Query Max Response Time
to enter the maximum query response time to be
advertised in IGMPv2 queries on this interface, in tenths of a second. The default value is
100. Valid values are from(0 to 255).
7.
Use
Startup Query Interval
to enter the number of seconds between the transmission of
startup queries on the selected interface. The valid values are from 1 to 300. The default
value is 31.
8.
Use
Startup Query Count
to enter the number of queries to be sent on startup. The valid
values are from 1 to 20. The default value is 2.
9.
Use
Last Member Query Interval
to enter the last member query interval in tenths of a
second. This the maximum response time to be inserted into group-specific queries sent in
response to leave group messages, and is also the amount of time between group-specific
query messages. Valid values are from 0 to 255. The default value is 10. This value is not
used for IGMP version 1.
10.
Use
Last Member Query Count
to enter the number of queries to be sent on receiving a
leave group report. Valid values are from 1 to 20. The default value is 2.
