IGMP and query interval

Hi all,

I am using Cisco 2950-24 with IOS version 12.1(22)EA4.
I use IGMP for send data to clients members of group multicast.

How can i set and print actuel Query interval configured on my switch to
send query to know who is interrested by multicast ? by default, it seem to
be 10 secondes on my switch.

How can set and print delay of Query Response and Query Count that the host
member should to send before leaving a host from the group ?

All this parameters seem not to be possible on my ios version !! I think
that in this case, i juste use default parameters.

The paremeter "last-member-query-interval = 1 secondes" seem to be used only
when a host leave message (when a host send leave message to leave a
multicast group).

So, i need to know, how can i force Query Interval, Query Count before
leaving host which no repond to the query and what is the Query Reponse
delay ?

There is the print of show ip igmp snooping on my switch :

CAT2950#sh ip igmp snooping
Global IGMP Snooping configuration:
IGMP snooping              : Enabled
IGMPv3 snooping (minimal)  : Enabled
Report suppression         : Enabled
TCN solicit query          : Disabled
TCN flood query count      : 2
Last member query interval : 1000

Vlan 1:
IGMP snooping                       : Enabled
Immediate leave                     : Disabled
Multicast router learning mode      : pim-dvmrp
Source only learning age timer      : 10
Last member query interval          : 1000
CGMP interoperability mode          : IGMP_ONLY

ThankYou very much

Best Regards
