Cisco 2600 Series Interface Numbering
Each network interface on a Cisco 2600 series router is identified by a slot number
and a port number.
Slot and Port Numbering
The Cisco 2600 series router chassis contains one slot in which you can install a
network module. This slot is always numbered 1. Both WAN interface card slots
built into the chassis, W0 and W1, are always numbered slot 0.
Port numbers identify the interfaces on the modules and WAN interface cards
installed in the router. Port numbers begin at 0 for each slot, and continue from
right to left and (if necessary) from bottom to top. Modules and WAN interface
cards are identified by interface type, slot number, a forward slash (/), and the port
number, for example Ethernet 0/0.
Figure 1-1 shows a router with a 2E 2-slot module in slot 1. One serial and one
ISDN BRI WAN interface card are installed in the module.
