Configuration Changes

•Protocols to be configured

To obtain this information, consult your network administrator. For additional interface configuration information for the RP and each of the line cards installed in your router, refer to the configuration note that shipped with each card.

GRP Ethernet Interfaces

The RJ-45 and MII receptacles on the faceplate of the GRP are IEEE

802.3u-compliant interfaces. These IEEE interfaces provide connectivity to Ethernet networks. You can use either interface, but not both at the same time.

The following configuration dialog example shows the system being configured for an Ethernet interface that will use the IP network layer protocol. (The Ethernet interface does not support external routing functions.) The IP address and subnet mask value below are examples. The actual IP address and subnet mask value would be different.

Configuring interface Ethernet0:

Is this interface in use?: yes

Configure IP on this interface?: yes

IP address for this interface: 3.3.1.1

Number of bits in subnet field: 8

Class A network is 3.0.0.0, 8 subnet bits; mask is 255.888.0.0

Configure CLNS on this interface?: yes

PRP Ethernet Interfaces

The IEEE 802.3 Ethernet interfaces on the PRP allow connections to external Ethernet networks and can transmit data rates of 10 Mbps and 100 Mbps. The transmission speed of the Ethernet ports is auto-sensing by default and is user configurable.

Caution The Ethernet ports are primarily used as Telnet ports into the 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.
