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). Interface Numbering Table 7 summarizes the interface numbering on a Cisco 2801 series router. Table 8 summarizes the interface numbering on Cisco 2811, Cisco 2821, and Cisco 2851 series routers. Note The interface numbering on Cisco 2800 series routers is different from the numbering on Cisco 2600 series routers. Note 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.
