Chapter 3 Installing the Cisco 10720 Internet Router Additional Configuration Features 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 Cisco IOS Software Configuration for the Cisco 10720 Internet Router publication. Assigning IP Information To assign IP addresses to interfaces, refer to "Configuring a Fast Ethernet Connection" in the Cisco IOS Software Configuration for the Cisco 10720 Internet Router publication. 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. 78-13062-10 Cisco 10720 Internet Router Installation and Configuration Guide 3-47
