Interface Numbering

Each individual interface (port) on a Cisco 1841 router is identified by a number. A Cisco 1841 router contains the following wide-area network (WAN) and local-area network (LAN) interface types:

•Two onboard Fast Ethernet LAN interfaces

•Two slots in which you can install WICs, VWICs (data only), and HWICs.

The numbering format for the slots is interface-type 0/slot-number/interface-number.Table 2-6summarizes the interface numbering.

1.The interfaces listed are examples only; other possible interface types are not listed.

2.VWICs are data-only in a Cisco 1841 router.

Note On the Cisco 1841 router, the numbering format for configuring an async interface is 0/slot/port. To configure the line associated with an async interface, simply use the interface number to specify the async line. For example, line 0/0/0 specifies the line associated with interface serial 0/0/0 on a WIC-2A/S in slot 0. Similarly, line 0/1/1 specifies the line associated with interface async 0/1/1 on a WIC-2AM in slot 1.
