Statement introduced in Junos OS Release 12.2 for ACX Series Universal Access Routers.

Description

Configure the interface speed. This statement applies to the management Ethernet interface (fxp0 or em0), Fast Ethernet 12-port and 48-port PICs, the built-in Fast Ethernet 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 routers with uPIMs installed and on MX Series routers, 1g (1 Gbps). You can specify the auto option only on MX Series routers.
