6506 Sup720 connectivity problem with 3500XL and 2950G
Recently I upgrade one catalyst switch 6506 with 2xSUP720 and 2x WS-X6724-SFP with LH SFP modules .
The problem is when disconnecting the optical links with the 3500XL and 2950G that was previously connected to the 6506 via an old WS-X6416-GBIC card with GBIC LH modules and connecting them to the new WS-X6724-SFP card there is no link between them .
Both the old ports on the WS-X6416-GBIC and new ones on the WS-X6724-SFP have the same trunk configuration and encapsulation.

I assume that you tried reversing the fiber pairs . The new fiber module came up ok when inserted ? If its a different module did you clear the config on that module when you inserted the new card and reconfigure it ? Besides that not sure what else it would be
