Each interface on the Cisco 3600 series is configured as a slot/unit number. Refer to Overview of Cisco
Network Modules for more information on how to identify the slot numbers. On the network module, the
interfaces are addressed as seen in this list:

The Ethernet interface is interface ethernet <slot>/0.

• 

The Token Ring interface is interface tokenring <slot>/0.

• 

A serial WIC, a T1 channel service unit/data service unit (CSU/DSU), or a 56/64k CSU/DSU WIC in
slot W0 is interface serial <slot>/0.

• 

A BRI−S/T WIC or BRI−U WIC in slot W0 is interface bri <slot>/0.

• 

A serial WIC, a T1 CSU/DSU, or a 56/64k CSU/DSU WIC in slot W1 is interface serial <slot>/0 if
slot W0 does not contain a serial port (serial WIC or 56/64k CSU/DSU). If slot W0 has a serial WIC,
the serial WIC in slot W1 is interface serial <slot>/1.

• 

A BRI−S/T WIC or BRI−U WIC in slot W1 is interface bri <slot>/0 if slot W0 does not contain a
BRI WIC. If slot W0 has a BRI WIC, the BRI WIC in slot W1 is interface bri <slot>/1.
