I'd like to know how many multicast groups my switch is currently subscribing to. Is there an SNMP mib that I can pull against to get a) the total number or b) total per interface that can sum together?

Anyone?

Have you read this?

The IGMP snooping MIB might do it?

Your other option might be to script the relevant show command to deliver its output somewhere.

Thanks for the input. I've been playing with this MIB already and have found some real useful data but most of total MCast packets through an interface vice any way to say "I am subscribing to x number of MCast groups". It's important in our environment as Cisco has some ceilings with the amount of MCast it can subscribe to. We use alot of MCast. I'll keep playing with it. Your scripting option is also a good option. I was hoping for some a little simpler but sometimes we gotta do what we gotta do. I find it interesting that there doesn't seem to be counter type MIB that does this.
