Of Topic:

Hello group, does anyone know if there is a limit to the number of multicast
senders sat on particular switch models?

I am having a problem where if there are more than 10 multicast streams on
2960 or 3560 the receiver suffers from significant loss of traffic and
frames, however using the same config on a 3750 I can have 32 streams
without incident.

The multicast is being sent to a router (3825) then passed over a GRE
tunnel. However as stated above using the 3750 to connect the senders works
fine, using a 2960 or 3560 works fine until 10 streams, at 11 all 11 just
fall apart

Any ideas before a TAC case?
