Configuring Ethernet Interfaces

Ethernet was developed in the early 1970s at the Xerox Palo Alto Research Center as a data-link control layer protocol for interconnecting computers. It was first widely used at 10 Mbps over coaxial cables and later over unshielded twisted pairs using 10BaseT. More recently, 100BaseTX (Fast Ethernet, 100 Mbps), Gigabit Ethernet (1 Gbps), and 10 Gigabit Ethernet have become available.

Juniper Networks routers support Fast Ethernet, Gigabit Ethernet, and 10 Gigabit Ethernet interfaces; a management Ethernet interface, which is an out-of-band management interface within the router; an internal Ethernet interface, which connects the Routing Engine to the Packet Forwarding Engine; and, an aggregated Ethernet interface, ...
