Introduction
The Command Line Interface (CLI) is a network management application
operated through an ASCII terminal without the use of a Graphic User
Interface (GUI) driven software application. By directly entering commands,
the user has greater configuration flexibility. The CLI is a basic command-line
interpreter similar to the UNIX C shell.
A switch can be configured and maintained by entering commands from the
CLI, which is based solely on textual input and output with commands being
entered by a terminal keyboard and the output displayed as text via a terminal
monitor. The CLI can be accessed from a console terminal connected to an
EIA/TIA-232 port or through a Telnet/SSH session.
This guide describes how the CLI is structured, describes the command
syntax, and describes the command functionality.
This guide also provides information for configuring the PowerConnect
switch, details the procedures, and provides configuration examples. Basic
installation configuration is described in the
completed before using this document.

detect misconfiguration of the peer DCB devices and,
optionally, for configuration of peer DCB devices.
FCoE Initialization Protocol (FIP) is used to perform the
functions of FC_BB_E device discovery, initialization and
maintenance. FIP snooping is a frame inspection method
used by FIP Snooping Bridges to monitor FIP frames and
apply policies based upon the L2 header information in
those frames, following recommendations in Annex C of
FC_BB_5 Rev 2.00
