We are trying to connect a fiber port from a 3560 Switch to a HP ProCurve 8000 switch but I am not getting any activity on either port. I know both work when connected to the same HP manufacturer switch on both sides but I can't make them talk to each other. (Cisco to HP NO), (HP to HP YES). I am new with the Cisco switches but I figured they would work regardless of the device. Any thoughts? The fiber tests fine. Does the Cisco fiber port need to be enabled?
Fiber cable doesn't have cross or straight.
You need to check the following:
1. is hp/cisco switch supporting single mode, multi mode or both
2. fiber come in pair for Tx and Rx. So try to swap at one side and check
After checking these 2 things, you should be already found out where went wrong.
HTH..plz rate if help.
