port on the FIC (M7i router), the built-in Ethernet interfaces on J Series Services Routers,
Combo Line Rate DPCs and Tri-Rate Ethernet Copper interfaces on MX Series routers,
and on the Gigabit Ethernet ports on J Series Services Routers with uPIMs installed and
configured for access switching mode. When you configure the Tri-Rate Ethernet copper
interface to operate at 1 Gbps, autonegotiation must be enabled. When you configure
100BASE-FX SFP, you must set the port speed at 100 Mbps.
Options You can specify the speed as either 10m (10 Mbps), 100m (100 Mbps), or on J Series
