Configuring the Ethernet Interface

The IEEE 802.3 Ethernet interface, located on the GRP, allows connections to external Ethernet networks and is capable of data transmission rates of 10 Mbps and 100 Mbps. At the auto-sensed data transmission rate of 100 Mbps, the Ethernet port provides maximum usable bandwidth that is less than 100 Mbps; expect a maximum usable bandwidth of approximately 20 Mbps for either the MII or RJ-45 connection. Transmission speed, which is not user configurable, is determined by the network to which the Ethernet interface is connected.

The Ethernet interface does not provide external routing functions; it is primarily designed as a Telnet port into the GRP, and for booting and/or accessing Cisco IOS software images over a network to which the Ethernet interface is directly connected.

Caution An Ethernet port is used primarily as a Telnet port into the Cisco 12000 Series Router, or for booting or accessing Cisco IOS software images over a network to which an Ethernet port is directly connected. Cisco Express Forwarding (CEF) functions are switched off by default for security reasons. Cisco strongly cautions you to consider the security implications of switching on CEF routing functions on these ports.

The following sections provide two methods for configuring the Ethernet interface.
