We have a 1g copper sfp in an mpim module, it won't negotiate at less than 1g whether forced or not. Is this possible?

RE: Newbie to Junos help please

What type of interface is facing it? In theory if you're autonegotiating speed and the other side is clocked at 100M, you should be able to negotiate to 100M. I'd recommend hard-coding speed in that case though, since FastE links don't deal with autonegotiation very well (802.3u was a vague standard).

When you say "whether forced or not", do you mean it wont take 100M if you hard-code your speed? If you do a 'set interface ge-x/x/x ether-options link-speed 100m', does that command not take?
