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 1-4for more examples.

	Table 1-4		Slot, Subslot (Bay) and Port Numbering
3-Tuple Example		Slot		Bay	Port
0/1/2		0		2nd	3rd
0/0/1		0		1st	2nd
1/1/1		1		2nd	2nd

•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..
