This document describes command-line interface (CLI) commands you use to view and configure Unified Switch software.
You can access the CLI by using a direct connection to the serial port or by using telnet or SSH over a remote network
connection.
A
UDIENCE
This document is for system administrators who configure and operate systems using Unified Switch software. It provides
an understanding of the configuration options of the Unified Switch software.
This document assumes that the reader has an understanding of the Unified Switch software base and has read the
appropriate specification for the relevant networking device platform. It also assumes that the reader has a basic knowledge
of Ethernet and networking concepts.
Refer to the release notes for the Unified Switch application-level code. The release notes detail the functionality of the
Switching, Routing, SNMP, Configuration, Management, and other packages.

The Unified Switch software has two purposes:
•
Assist attached hardware in switching frames, based on Layer 2, 3, or 4 information contained in the frames.
•
Provide a complete device management portfolio to the network administrator.
S
COPE
Unified Switch software encompasses both hardware and software support. The software is partitioned to run in the following
processors:
•
CPU
This code runs the networking device management portfolio and controls the overall networking device hardware. It also
assists in frame forwarding, as needed and specified. This code is designed to run on multiple platforms with minimal
changes from platform to platform.
•
Networking device processor
This code does the majority of the packet switching, usually at wire speed. This code is platform dependent, and
substantial changes might exist across products.
