Interface Card Ports
Interface cards can be inserted either directly into a router slot or into a slot in a network module.
Interface Card in Router
Interface cards inserted into a router slot are numbered 0/HWIC-slot/port. HWIC-slot is 0, 1, 2, or 3, as labeled on the router
rear panel.
Double-wide interface cards use slot numbers 1 and 3.
Note
Ports in an interface card are normally numbered from right to left and bottom to top, starting at 0. See the
Cards Installation Guide
Interface Card in Network Module
Some network modules provide slots for interface cards. Ports in these interface cards are numbered
router-slot/module-slot/port, where router-slot is 1, 2, 3, or 4.
Double-wide or extended double-wide network modules use slot numbers 2 and 4.
Note
Slots in network modules for interface cards are normally numbered from right to left, starting at 0. Ports in an interface card
are normally numbered from right to left and bottom to top, starting at 0. For more information, see the
Hardware Installation Guide
Note
On the Cisco 3825 and Cisco 3845 routers, the interface numbering scheme is the same for asynchronous interfaces as other
types of interfaces. To configure the line associated with an async interface, simply use the interface number to specify
the async line. For example, line 0/3/0 specifies the line associated with interface serial 0/3/0 on a WIC-2A/S in slot 3.
Similarly, line 1/22 specifies the line associated with interface async 1/22 on an NM-32A in network module slot 1.

Perform Initial Configuration
You can configure your router by using one of the following tools:
• Cisco Router and Security Device Manager (SDM)—See the "Initial Configuration Using Cisco Router and Security Device
Manager (SDM)" section on page 30.
• Setup command facility—See the "Initial Configuration Using the Setup Command Facility" section on page 31.
• Command-line interface (CLI)—See the "Initial Configuration Using the Cisco CLI—Manual Configuration" section on
page 33.
If you need help with the interface and port numbering, see the "Port Numbering" section on page 29.
Note
Initial Configuration Using Cisco Router and Security Device Manager (SDM)
If the following messages appear at the end of the startup sequence, Cisco Router and Security Device Manager (SDM) is
installed on your router:
yourname con0 is now available
Press RETURN to get started.
For instructions on configuring your router by using SDM, see the Cisco Router and Security Device Manager (SDM) Quick
Start Guide that shipped with your router.
