56 IP Multicasting Enhancements Release Note
Software Version 2.9.1
C613-10486-00 REV C
Once the Querier receives the Query Solicit message, it sends out a General
Query and waits for responses, which update the snooping information
throughout the network. If necessary, you can reduce the time this takes by
tuning the IGMP timers, especially the queryresponseinterval parameter. For
more information, see the “IGMP Timers and Counters” section of How To
Configure IGMP on Allied Telesyn Routers and Switches for Multicasting. This How
To Note is available in the Resource Center of the Documentation and Tools
CDROM for Software Version 2.8.1, or from
www.alliedtelesis.co.uk/en-gb/solutions/techdocs.asp?area=howto
Disabling Query Solicitation and Display Settings
On switches other than the STP root bridge or EPSR master node, you can
disable query solicitation by using the command:
set igmpsnooping vlan={vlan-name|1..4094|all}
querysolicit={off|no|false}
To see whether query solicitation is on or off, use the command:
show igmpsnooping
Check the new Query Solicitation field.
Changes to IGMP Snooping Fast Leave Command Syntax
The command syntax for the Fast Leave feature has also been changed, to make
it more like the syntax for the query solicitation feature.
To enable Fast Leave on a specific VLAN, or all VLANs on the switch, the new
syntax is:
set igmpsnooping vlan={vlan-name|1..4094|all}
fastleave={on|yes|true}
To disable Fast Leave on a specific VLAN, or all VLANs on the switch, the new
syntax is:
set igmpsnooping vlan={vlan-name|1..4094|all}
fastleave={off|no|false}
The original syntax was:
set igmpsnooping fastleave={on|yes|true|off|no|false}
[interface=vlan]
This original syntax is still valid, but we recommend using the new syntax
instead.
