We have a switch (Cisco WS-C3750G-48TS) with only a C3750-IPBASE-M image (not a 'C3750-IPSERVICES-M' license). Is there any kind of multicast support here?

All I need it to do is route multicast packets to an RP (ip pim sparse-mode). Do we really need the service (C3750-IPSERVICES-M) license/image?. The uplink switch is running C3750-IPSERVICES-M, but this switch doesn't seem to carry any ability to configure multicast on an interface.

According to the Cisco Feature Navigator the 3750 supports PIM version 1 on the following releases:

  • 12.1 EMI Image
  • 12.2(50)SE or lower EMI Image or IP Services
  • 12.2(52)SE or higher IP Base
  • 15.0 IP Base

I wish I were 100% sure but I'm pretty sure you can do regular IGMP snooping based multicast with the base code on 3750's - we do it one larger boxes but these instructions suggest you can do it on those boxes too.

What is the output of ip multicast-routing? That will tell you if you have the capability or not. If not, you will probably need to upgrade your IOS.
