Cisco 3600 Series Routers
Unit Numbering
Cisco 3600 series routers unit numbers identify the interfaces on the modules and WAN
interface cards installed in the router. Unit numbers begin at 0 for each interface type, 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, followed by a forward slash
(/), and then the unit number; for example, Ethernet 0/0.
Figure 1-3 shows a router with a 2E 2-slot module in slots 0 and 1. Two serial WAN
interface cards are installed in the module in slot 0. One serial and one ISDN BRI WAN
interface card are installed in the module in slot 1.
