    0/slot/port. “0” indicates slots that are built into the chassis of a router. On the Cisco 2901 router, all slots begin with “0,” because all slots are built into the chassis. On the Cisco 2911, 2921, 2951, and Cisco 3900 series routers, some slots are built into the chassis and some are external.

    1. On the Cisco 2901 router, the numbering format for configuring an asynchronous interface is 0/slot/port. To configure the line associated with an asynchronous interface, use the interface number to specify the async line. For example, line 0/1/0 specifies the line associated with interface serial 0/1/0 on a WIC-2A/S in slot 1.
