The Fast Ethernet, fxp0, and em0 interfaces can be configured for 10 Mbps or 100 Mbps (10m | 100m). The J Series Gigabit Ethernet uPIM interfaces and the MX Series Tri-Rate Ethernet copper interfaces can be configured for 10 Mbps, 100 Mbps, or 1 Gbps (10m | 100m | 1g). The 4-port and 8-port Fast Ethernet PICs support a speed of 100 Mbps only. MX Series routers support Gigabit Ethernet automatic line sensing of MDI (Media Dependent Interface) and MDIX (Media Dependent Interface with Crossover) port connections. MDI is the Ethernet port connection typically used on network interface cards (NIC). MDIX is the standard Ethernet port wiring for hubs and switches. This feature allows MX Series routers to automatically detect MDI and MDIX connections and configure the router port accordingly. You can disable this feature by using the no-auto-mdix statement at the [edit interfaces ge-fpc/pic/port] hierarchy level. NOTE: Junos OS supports Ethernet host addresses with no subnets. This enables you to configure an Ethernet interface as a host address (that is, with a network mask of /32), without requiring a subnet. Such interfaces can serve as OSPF point-to-point interfaces, and MPLS is also supported. To configure physical interface properties specific to Gigabit Ethernet and 10-Gigabit Ethernet, include the gigether-options statement at the [edit interfaces ge-fpc/pic/port] or [edit interfaces xe-fpc/pic/port] hierarchy level: Chapter 2: Configuring Ethernet Interfaces [edit interfaces ge-fpc/pic/port] gigether-options { 802.3ad aex (primary | backup); auto-negotiation | no-auto-negotiation) remote-fault ; (flow-control | no-flow-control); 37
