Chapter 3 Installing the Cisco 10720 Internet Router

Configuring Fast Ethernet

The basic Fast Ethernet configuration task for the router is located in the Cisco IOS Software
Configuration for the Cisco 10720 Internet Router publication under "Configuring a Fast Ethernet
Interface."

Configuring Gigabit Ethernet

The basic Gigabit Ethernet configuration task for the router is located in the Cisco IOS Software
Configuration for the Cisco 10720 Internet Router publication under "Configuring a Gigabit Ethernet
Interface."

Configuring TDR on TX Access Card

The Time Domain Reflectometer (TDR) sends a signal from one end of a cable and measures the time
for the signal to reflect back. To detect shorts and breaks, to measure the length of the cable, and to find
other physical-layer network problems, use the TDR.
The TDR is used for Fast Ethernet ports on 10/100BASE-TX and 4-Port Gigabit Ethernet 8-Port 10/100
Ethernet TX access cards. For information about how to use the TDR, refer to "Testing for a Cable
Problem on a Fast Ethernet Interface" in the
Internet Router

Assigning IP Information

To assign IP addresses to interfaces, refer to "Configuring a Fast Ethernet Connection" in the
Software Configuration for the Cisco 10720 Internet Router

Enabling Write Permission to Bootflash

The router provides 64 MB of Flash memory. There are 16 MB dedicated to the bootflash, a read-only
partition containing the Cisco IOS software image that shipped with the router. There are 48 MB
dedicated to the Flash, a read-write partition containing downloaded Cisco IOS software images.
To enable the write permission to the bootflash, use the bootflash-write enable command.
router(config)# bootflash-write enable
Caution Writing to bootflash memory is not recommended.

Upgrading the Cisco IOS Software Image

You can upgrade the Cisco IOS software image on the router by copying the image to Flash memory and
then restarting the router using the updated image.
