These standards-based management methods allow you to configure and monitor the components of the
QNOS software. The method you use to manage the system depends on your network size and
requirements, and on your preference.
Note: Not all features are supported on all hardware platforms, so some CLI commands and object
identifiers (OIDs) might not available on your platform.
2.4.1. Using the Command-Line Interface
The command-line interface (CLI) is a text-based way to manage and monitor the system. You can access the
CLI by using a direct serial connection or by using a remote logical connection with telnet or SSH.
The CLI groups commands into modes according to the command function. Each of the command modes
supports specific software commands. The commands in one mode are not available until you switch to that
particular mode, with the exception of the User EXEC mode commands. You can execute the User EXEC mode
commands in the Privileged EXEC mode.
To display the commands available in the current mode, enter a question mark (?) at the command prompt.
To display the available command keywords or parameters, enter a question mark (?) after each word you
type at the command prompt. If there are no additional command keywords or parameters, or if additional
parameters are optional, the following message appears in the output:
<cr> Press Enter to execute the command
For more information about the CLI, see the QNOS CLI Command Reference.
The QNOS CLI Command Reference lists each command available from the CLI by the command name and
provides a brief description of the command. Each command reference also contains the following
information:
The command keywords and the required and optional parameters.
The command mode you must be in to access the command.
The default value, if any, of a configurable setting on the device.
The
show
commands in the document also include a description of the information that the command
shows.
2.4.2. Using SNMP
SNMP is enabled by default. The show
sysinfo
command displays the information you need to configure an
SNMP manager to access the switch. You can configure SNMP groups and users that can manage traps that
the SNMP agent generates.
QNOS uses both standard public MIBs for standard functionality and private MIBs that support additional
switch functionality. All private MIBs begin with a “-” prefix. The main object for interface configuration is in
-SWITCHING-MIB, which is a private MIB. Some interface configurations also involve objects in the public MIB,
IF-MIB.
