Is there any special config needed w/ Cisco switches in order to perform
multicast operations?? I have recently put in some Cisco 3500 (3500XL &
3550) switches, but now I can't perform multicast operations. I have enabled
STP PortFast, yet the client still won't join the multicast session. I am
manually creating the session from the server console, and the workstations
are PXE booting, with a valid IP, mask & gateway. I can perform manual
image operations via PXE boot, just not multicast. Thanks in advance!!
