We are using 3560 and 3750 PoE switches in a network which interconnects a lot of clients using a proprietary VoIP software solution.
This Software uses Multicast groups for communication and now we are running into the limitation of 1000 multicast groups supported by these switches.
Does anybody know if there is any possibility to extend the maximum number of Multicast groups on the 3560 and 3750 Cisco switches? IOS update? Memory extension?
Thanks in advance for your help
Hi Johannes,

Provides the following information:
Currently, we support only 1024 multicast routes+IGMP groups.
To extend the maximum number, we need code changes.
At the moment, no code changes planned.

Hope this helps.
