Well, I was actually talking about 100BaseTX ports, not SFP ports like the subject. However, in my case, it is AT&T (former BellSouth) copper metroE connections where they use a Canoga box. They only provision them with autonegotiation disabled. We also just got a metroE from Charter Cable (I don't know what the box is) and they made sure we disabled autoneg because that's the only way the configure their equipment (which beats AT&T; we had to find out on our own that they disable autoneg). IIRC a Knology Cable metroE was the same way. These are 10 and 100 meg metroE connections; I don't know what these companies do for gigE. -- Chris Adams <[EMAIL PROTECTED]> Systems and Network Administrator - HiWAAY Internet Services I don't speak for anybody but myself - that's enough trouble. _______________________________________________ juniper-nsp mailing list juniper-nsp@puck.nether.net https://puck.nether.net/mailman/listinfo/juniper-nsp
