Not to mention using the same model numbers for MX SFPs and EX SFPs (the order numbers are different) so once you have them installed (or even out of their original packaging), you can't tell which is which, and then having support issues when one works and the other doesn't because you used it in the "wrong" platform. Been there, done that. _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
