CLI Command Notation Conventions
When entering commands there are certain command-entry notations which apply to all
commands. The following table describes these conventions as they are used in syntax definitions.
Interface Naming Conventions
The conventions for naming interfaces in CLI commands are as follows:
• Unit#/Interface ID—each interface is identified by the
Unit# followed by a </> symbol
and then the
Interface ID . For example, 2/g10 identifies the gigabit port 10 within the
second unit.
• Unit#—the unit number is used only in a stacking solution where a number of switches
are stacked to form a virtual switch. In this case, the
Unit # identifies the physical switch
identifier within the stack.
• Interface ID—is formed by the interface type followed by the interface number. For
example,
2/g10 identifies the gigabit port 10 on the second unit; 1/g1 identifies the fast
Ethernet port 1 on the first unit within the stack.
• Interface Types—the following interface types are defined.
g stands for gigabit Ethernet
port (for example,
g2 is the gigabit port 2). xg stands for 10 Gigabit Ethernet port (for
example, xg2 is the 10 gigabit Ethernet port 2).
CLI Command Modes
Since the set of CLI commands is very large, the CLI is structured as a command-tree hierarchy,
where related command sets are assigned to command modes for easier access. At each level, only
the commands related to that level are available to the user and only those commands are shown in
the context sensitive help for that level.
Convention Description
[ ] In a command line, square brackets indicate an optional entry.
{ } In a command line inclusive brackets indicate a selection of compulsory
parameters separated by the |character. One option must be selected. For
example:
flowcontrol {auto|on|off} means that for the flowcontrol
command either
auto , on or off must be selected.
Italic Indicates a variable.
< Enter > Any individual key on the keyboard.
< Ctrl >+< F4 > Any combination of keys pressed simultaneously on the keyboard.
Screen
Display
Indicates system messages and prompts appearing on the console.
all
Indicates a literal parameter, entered into the command as it is.
