Network Connection Considerations
Network Connection Considerations
This section describes the considerations for each type of network connection available for a
Cisco 4000 series router.
Ethernet Connections
The following sections describe the two types of Ethernet network processor modules: single-port
and dual-port modules.
Note The single-port Ethernet network processor module is not supported on the Cisco 4500-M
and Cisco 4700.
Single-Port Ethernet Module Connections
Each single-port Ethernet network processor module has an Ethernet AUI connector and a 10BaseT
connector. (See Figure 2-5.) (Only one connector on the module can be used at a time.) Use either
an IEEE 802.3 AUI or a 10BaseT cable to make the connection.
Selecting the Media Type
The media type connection, AUI or 10BaseT, is selected by the media command. Enter the media
command in the router’s configuration file to configure your selection of AUI or 10BaseT on the
desired interface. The syntax of the media command follows:
media–type aui
media–type aui 10baset
The following is an example of configuring the Ethernet 0 interface for a media type AUI
connection:
router> enable
Password:
router# configure terminal
Enter configuration commands, one per line.
Edit with DELETE, CTRL/W, and CTRL/U; end with CTRL/Z
interface ethernet 0
media-type aui
^z
router# write memory
Refer to the router software publications for more information on the media command.
