Using show Commands to Check the Installation Chapter 4 Observing System Startup and Performing a Basic Configuration • Loading configuration files or system images using remote copy protocol (rcp) or Trivial File Transfer Protocol (TFTP) • Reloading the operating system Using show Commands to Check the Installation Use show commands to identify the hardware installed in your router, to verify the operation status, to view interface configuration settings, and to troubleshoot your router configuration. The interfaces on the NPE-G1 or NPE-G2 are identified by their chassis slot number and interface port number (slot/port). The interfaces on your I/O controller are also identified by chassis slot number and interface port number (slot/port). The chassis slot number for the I/O controller is always slot0. Table 4-1 lists the NPE-G, NPE-G2, and the I/O controller models, their corresponding interfaces, and the interface addressing syntax for each interface.

Both optical and copper ports report the same syntax. For example, Gigabit Ethernet RJ-45 port 0/2 reports GigabitEthernet 0/2, as does Gigabit Ethernet GBIC port 0/2. 2. The Product Number C7200-I/O-FE does not specify MII because both an MII and an RJ-45 receptacle are included. 3. The I/O controller with the Product Number C7200-I/O-FE-MII has a single MII FastEthernet receptacle only. Although still supported by Cisco Systems, this I/O controller with a single MII receptacle is no longer an orderable product as of May 1998. 4-16 Cisco 7200 VXR Installation and Configuration Guide OL-5013-09
