 summarizes the interface numbering on a Cisco 2801 series router. 

 summarizes the 

interface numbering on Cisco 2811, Cisco 2821, and Cisco 2851 series routers.

The interface numbering on Cisco 2800 series routers is different from the numbering on Cisco 2600 
series routers.

On the Cisco 2801 router, the numbering format for slots is interface type 0/slot/port. “0” indicates slots 
that are built into the chassis of a router. On the Cisco 2801 router, all slots begin with “0,” because all 
slots are built into the chassis. Note that this is different from the Cisco 2811, Cisco 2821, and 
Cisco 2851 routers. On these routers, some slots are built into the chassis and have slot numbers that 
begin with “0”. However, it is possible to have other slots that are part of a network module or an 
extension voice module. Those slots have slot numbers that begin with “1” or “2,” respectively.

Gigabit Ethernet port 0/0

High-speed WAN interface card slot 3

Gigabit Ethernet port 0/1

Extension voice module (EVM) slot

High-speed WAN interface card slot 0

The network module slot is compatible with Cisco network modules of type NM (network module), NME (network module enhanced), NME-X 
(enhanced extended), NMD (double-wide), and NME-XD (enhanced extended double-wide).
