Table 6 Interface Numbering on Cisco 2801 Series Routers Slot Number Slot Type Interface Numbering Range Onboard ports Fast Ethernet 0/0 and 0/1 0 VIC/VWIC (voice only-no PRI support) 0/0/0 to 0/0/3 1 HWIC/WIC/VIC/VWIC1 0/1/0 to 0/1/3 (single-wide HWIC) 0/1/0 to 0/1/8 (double-wide HWIC) 2 WIC/VIC/VWIC1 0/2/0 to 0/2/3 3 HWIC/WIC/VIC/VWIC1 0/3/0 to 0/3/3 (single-wide HWIC) 0/3/0 to 0/3/8 (double-wide HWIC) 1. A VWIC in slots 1, 2, and 3 can operate in both data and voice mode; in slot 0, a VWIC can operate only in voice mode. Note On the Cisco 2801 router, the numbering format for configuring an asynchronous interface is 0/slot/port. To configure the line associated with an asynchronous interface, simply use the interface number to specify the asynchronous 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. Similarly, line 0/2/1 specifies the line associated with interface async 0/2/1 on a WIC-2AM in slot 2.
