By Greg Whynott -
I swear there was a time when you could grab any SFP and use it without much thought or problems.
Then all of a sudden it seemed like Cisco decided you couldn't use other peoples SFP's in their kit. and 3 minutes later it seemed as if the rest of the industry followed suite.
forgive my ignorance but in my mind there is power applied to a few legs of the SFP and magically a diode lights up emitting light of a certain wave length.
One night after driving into work at 11PM and being there for 4 hours it was obvious the problem was a failed SFP. I finally convinced the TAC guy (after he mistakenly hinted about it) to give me the _magical_ command to force the 6509e switch to not care about the brand name of the SFP. I had other long range ones on hand but they were for the Nortel switches and made by finisar.
he did and to my knowledge 6 years later that same SFP is in service.
whats with all this vendor hate... it causes us admins so much grief. Its even sadder when you consider there are not may shops that make SFPs and most every vendor SFP is a re-branded finisar or similar.
today I went to put a Dell SFP into a Dell switch and was met with this message:

super *sigh*... yes I realize the merger is recent... didn't take them to long to get their name/logo on everything else tho:

while pee'n in all corners to ensure everyone knew who was who, perhaps also modify that check code?
anyway this isn't a Dell hate thing, Dell has been a great experience for us thus far, everyone is doing it, its just the latest of many hurdles and brought back bad memories.

ok.. anyone know what the magical 'don't care what SFP you are using" command is for Force10 products? 8)
