Description

Configure the interface speed. This statement applies to the following interfaces:

  • Management Ethernet interface (fxp0 or em0)

  • Fast Ethernet 12-port and 48-port PICs

  • Built-in Fast Ethernet port on the FIC (M7i router)

  • Combo Line Rate DPCs and Tri-Rate Ethernet Copper interfaces on MX Series routers

  • Gigabit Ethernet interfaces on EX Series switches

If you enable autonegotiation, then the device automatically negotiates the speed based on the speed of the other end of the link. Table 1 describes the autonegotiation option available for different platforms:

Table 1: Autonegotiation Options

Autonegotiation Option

Description

auto-negotiation

Automatically negotiate the speed based on the speed of the other end of the link.

auto

Automatically negotiate the speed (10 Mbps, 100 Mbps, or 1 Gbps) based on the speed of the other end of the link.

auto-10m-100m

Automatically negotiate the speed (10 Mbps or 100 Mbps) based on the speed of the other end of the link.

See Speed and Autonegotiation for more details.

Options

Routers support autonegotiation by default. To enable or disable autonegotiation, see autonegotiation (Routers). Table 2 summarizes the speed and autonegotiation supported on different routing platforms:
