7Interface Numbering

Each individual interface (port) on Cisco 2600XM series and Cisco 2612 routers is identified by number as described in the following sections.

WAN and LAN Interface Numbering

Cisco 2600XM series and Cisco 2612 router chassis contain the following WAN and LAN interface types:

•Built-in LAN interfaces: Ethernet, FastEthernet, Token Ring

•Two or three slots in which you can install WAN interface cards (WICs)

•One slot in which you can install a network module

The numbering format is Interface-typeSlot-number/Interface-number. Two examples are:

•Ethernet 0/0

•Serial 1/2

The slot number is 0 for all built-in interfaces and 0 for all WIC interfaces; the slot number is 1 for network module interfaces. Interface (port) numbers begin at 0 for each interface type, and continue from right to left and (if necessary) from bottom to top. Figure 13 shows a router of 1-RU height with:

•A WIC in each WIC slot (containing interface Serial 0/0 in physical slot W0, and interface Serial 0/1 in physical slot W1)

•A 4-serial-port network module in slot 1 (containing the following ports: Serial 1/0, Serial 1/1, Serial 1/2, and Serial 1/3)
