[c-nsp] Nemtwork Management System for ip-multicast at layer 2

[Sergey Voropaev]

Salute guys!

Could any one advice NMS for monitoring ip multicast network at L3
devices like as routers and also at L2 igmp-snooping enable switches?
The main purpose for example is to draw network diagram for particular
mcast group including all source and recievers, and source and
receivers must be drawn with detailing of switches' ports this nodes
belong to. I already tried cisco Multicast Manager and CA cpectrum.
But this products do not not understand igmp snooping and can not
parse IGMP information from L2 switches.
