I configured the interfaces individually at L3 and could ping across each link
Example:
4500 Switch 2: 6500 Switch 1
int t5/1 - int g3/17 1 Gig fiber link
tore down config
tried second set of interface
int t6/1 - int g8/17 1 Gig fiber link
Ping successful
created a port-channel
PO21 - PO217
added int T5/1 and G3/17 to the associated port-channel and ping failed.
int T5/1

int G3/17
