hey Pavel,
its you again, thnx for the reply...
its none of the tech stuff this time around.....I used mozilla for
DMP's web management & issue multicast group joins, for some reason
mozilla does not seems to work with cisco 4305 dmp's, though on the
browser says "request sent successful", DMP's do not respond to it &
hence no IGMP join request's.....to add to the list, I checked those
that weren't having any issue & bcoz of this mozilla issue no logs
were seen even from the working DMP's causing more worries...
with IE every thing worked well.......though I knew this, it had
slipped my mind between issues :-)))
tnx/Mahesh
