Press RETURN to get started! RETURN
Step 12 The user prompt is displayed:
When you have completed the basic configuration tasks, your Cisco router is ready to configure for specific functions. See the "Where to Go Next" section for information about locating documentation for advanced configuration procedures.
Initial Configuration Using the CLI (Manual Configuration)
This section shows how to bring up a command-line interface (CLI) prompt for configuration using the CLI, and it directs you to documentation for the CLI configuration.You can use the CLI if you see the following messages at the end of the startup sequence:
--- System Configuration Dialog ---
At any point you may enter a question mark '?' for help.
Use ctrl-c to abort configuration dialog at any prompt.
Default settings are in square brackets '[]'.
Would you like to enter the initial configuration dialog? [yes/no]:
If these messages do not appear, SDM and a default configuration file have been installed on the router at the factory. To use SDM to configure the router, see the "Initial Configuration Using Cisco Router and Security Device Manager" section.
For interface numbering information, see the "Interface Numbering" section.
Step 1 To proceed with manual configuration using the CLI, enter no.
Would you like to enter the initial configuration dialog? [yes/no]: no
Step 2 Press Return to terminate autoinstall and continue with manual configuration.
Would you like to terminate autoinstall? [yes] Return
Several messages are displayed, ending with a line similar to the following:
Copyright (c) 1986-2002 by cisco Systems, Inc.
Compiled date time by person
Step 3 Press Return to bring up the Router> prompt.
flashfs[4]: Initialization complete.
Step 4 Enter privileged EXEC mode.
Note To avoid losing work you have completed, be sure to save your configuration occasionally as you proceed. Use the copy running-config startup-config command to save the configuration to NVRAM.
For configuration using the CLI, refer to the applicable configuration procedures in the Software Configuration Guide: Cisco 2600 Series, Cisco 3600 Series, and Cisco 3700 Series Routers. See the "Where to Go Next" section for information about accessing this document.
7 Interface Numbering
Each individual interface (port) on a Cisco 3745 router is identified by number as described in the following sections.
WAN and LAN Interface Numbering
The Cisco 3745 router chassis contains the following WAN and LAN interface types:
•2 built-in FastEthernet LAN interfaces
•3 slots in which you can install WAN or voice interface cards
•4 network module slots
The numbering format is:
•Interface-type Slot-number/Interface-number
Two examples are: FastEthernet 0/0 and Serial 1/2.
The slot numbers are as follows:
•0 for all built-in interfaces
•0 for all WIC interfaces
•1 for the lower-right network module slot
•2 for the lower-left network module slot
•3 for the upper-right network module slot
•4 for the upper-left network module slot
If double-width network modules are installed, the network module slots are numbered as follows:
•2 for the lower double-width slot
•4 for the upper double-width slot
Interface (port) numbers begin at 0 for each interface type, and continue from right to left and from bottom to top.
Figure 7 shows the back panel of the Cisco 3745 with:
•A WIC in each of the three WAN interface card slots
•A single-width network module in each of the four network module slots
•Two AC power supplies
Note The slot number for all WIC interfaces is always 0. (The W0, W1, and W2 slot designations are for physical slot identification only.) Interfaces in the WICs are numbered from right to left, starting with 0/0 for each interface type, regardless of which physical slot the WICs are installed in. Some examples are:
–If physical slot W0 is empty and physical slot W1 contains a 1-port serial WIC, the serial interface in the WIC is numbered Serial 0/0.
–If slot W0 contains a 2-port serial WIC and slot W1 contains a 1-port serial WIC, the serial interfaces in physical slot W0 are numbered Serial 0/0 and Serial 0/1, and the serial interface in physical slot W1 is numbered Serial 0/2.
–If slot W0 contains a 2-port serial WIC and slot W1 contains a 1-port BRI WIC, the serial interfaces in physical slot W0 are numbered Serial 0/0 and Serial 0/1, and the BRI interface in physical slot W1 is numbered BRI 0/0.
