Very likely no. What's the SFP model number and the line card type you're using on the MX?

Trying to connect GE copper SFP on MX to a 100meg port on a cisco switch, 3560 actually.

ge-0/0/2 { description "<< Test Link >>"; enable; speed 100m; link-mode full-duplex; unit 0 { family inet { address; show interface ge-0/0/2: Physical interface: ge-0/0/2, Enabled, Physical link is Up Interface index: 136, SNMP ifIndex: 511 Description: << Test Link >> Link-level type: Ethernet, MTU: 1514, Speed: 100mbps, BPDU Error: None, MAC-REWRITE Error: None, Loopback: Disabled, Source filtering: Disabled, Flow control: Enabled, Auto-negotiation: Enabled, Remote fault: Online Device flags   : Present Running Interface flags: SNMP-Traps Internal: 0x4000 Link flags     : None CoS queues     : 8 supported, 8 maximum usable queues Current address: 80:71:1f:91:10:02, Hardware address: 80:71:1f:91:10:02 Last flapped   : 2011-04-28 13:44:09 PDT (1w5d 03:08 ago) Input rate     : 0 bps (0 pps) Output rate    : 0 bps (0 pps) Active alarms  : None Active defects : None Logical interface ge-0/0/2.0 (Index 74) (SNMP ifIndex 522) Flags: SNMP-Traps

I can configure them as such
but do they actually work at 100M? Thanks,
