Chapter 1 Overview of the Routers
Table 1-12 Interface Numbering on Cisco 2911, 2921, 2951 ISRs and Cisco 3900 ISRs (continued)
Port Location
Voice port in a BRI expansion
module (internal slot) in an
extension voice module (EVM)
BRI interface in a BRI expansion
module (internal slot) in an
extension voice module
1. Interface abbreviations: fa = Fast Ethernet; gi = Gigabit Ethernet; USB = universal serial bus; BRI = ISDN basic rate interface.
2. The interfaces listed are examples only; other possible interface types are not listed.
3. Only interface card slot numbers 1 and 3 are used for double-width (HWIC-D).
4. Specify the line number in the Cisco IOS command-line interface (CLI) by using the interface number for the associated asynchronous serial
interface.
5. The network module slot number is 1 for all Cisco 2900 series routers.
Note On the Cisco 2911, 2921, 2951 routers and Cisco 3900 series routers the interface numbering scheme is
the same for asynchronous interfaces as for other types of interfaces. To configure the line associated
with an async interface, 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 an 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.
