Sounds like it should based on your description. You should make sure =
other media settings match, such as speed, etc.. While this may seem =
illogical on a 1G SFP, some devices have varying expectations of that, =
so sometimes "speed nonegotiate" is necessary.
If you are going from HP-HP to Cisco-HP, you may need to disable their =
transciever eeprom check on the Cisco side.
