Multicast group capacity

We are using 3560 and 3750 PoE switches in a network which

interconnects a lot of clients (WIN XP professional) 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

Re: Multicast group capacity

Hi,

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.

Tom.
