Statement introduced before Junos OS Release 7.4.
Statement introduced in Junos OS Release 12.2 for ACX Series Universal Access Routers.
Statement introduced in Junos OS Release 13.2X50-D10 for EX Series switches.
Configure the interface speed. This statement applies to the management Ethernet
interface ( or ), Fast Ethernet 12-port and 48-port PICs, the built-in Fast Ethernet
fxp0 em0
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,
Gigabit Ethernet ports on J Series Services Routers with uPIMs installed and configured
for access switching mode, and Gigabit Ethernet interfaces on EX Series switches.
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.
You can specify the speed as either
