Chapter 1 Overview of the Cisco 4451-X Integrated Services Router
About Slots and Interfaces
In most cases, the router designates its interfaces using a 3-tuple notation that lists the slot, bay, and
port. The 3-tuple value is zero based. An example of a 3-tuple is 0/1/2. This refers to slot 0, the
second bay in slot 0 (the first bay is 0 so the second bay is 1), and the third port in bay 1. See
Table 1-4 for more examples.
Table 1-4 Slot, Subslot (Bay) and Port Numbering
Slots and bays are numbered from the left to the right, and from the top to the bottom.
NIMs are designated by the number of the first slot that they occupy. A NIM occupies two slots, but
its designation is only the left-most slot number (double-wide cards only).
The auxiliary (AUX) serial port and console (CON) serial port do not have slot, bay, or port
numbers.
The GE management port is named GE 0. It does not have a slot, bay, or port number.
The two USB ports are named USB0 and USB1. They do not have slot, bay or port numbers
Note USB0 and USB1 can be used to insert flash drives..
Figure 1-9 shows the ports and slots on the Cisco ISR 4451-Xs.
3-Tuple Example Slot Bay Port
0/1/2 0 2nd 3rd
0/0/1 0 1st 2nd
1/1/1 1 2nd 2nd
