Management application overview
This chapter describes the different applications you can use to manage the devices. The Extreme Networks devices support the same
management applications as other devices.
As with other devices, you can manage a device using any of the following applications:
•
Command Line Interface (CLI) - a text-based interface accessible directly from a PC or terminal attached to the device’s serial
(Console) port or 10BaseT/100BaseTX Ethernet (management) port, or from a Telnet connection to the PC or terminal.
•
Extreme Network Advisor - An optional SNMP-based standalone GUI application. For more information see the
Unified IP MIB
reference manual
.
The following section describes how to log on to these applications.
CLI Functionality
Once an IP address is assigned to the Extreme Networks device’s management port, you can access the CLI through a PC or terminal
attached to the device’s serial (Console) port or 10BaseT/100BaseTX Ethernet (management) port, or from a Telnet or SSH connection
to the PC or terminal.
You can initiate a local Telnet, SSH or SNMP connection by specifying the management port’s IP address.
The commands in the CLI are organized into the following levels:
•
User EXEC - Lets you display information and perform basic tasks such as pings and traceroutes.
•
Privileged EXEC - Lets you use the same commands as those at the User EXEC level plus configuration commands that do
not require saving the changes to the system-config file.
•
CONFIG - Lets you make configuration changes to the device. To save the changes across software reloads and system resets,
you need to save them to the system-config file. The CONFIG level contains sub-levels for individual ports, for VLANs, for
routing protocols, and other configuration areas.
NOTE
By default, any user who can open a direct or Telnet connection to an Extreme Network device can access all these CLI levels.
To secure access, you can configure Enable passwords or local user accounts, or you can configure the device to use a
RADIUS or TACACS/ server for authentication.
Online help
To display a list of available commands or command options, enter "
?
" or press Tab. If you have not entered part of a command at the
command prompt, all the commands supported at the current CLI level are listed. If you enter part of a command, then enter "
?
" or
press Tab, the CLI lists the options you can enter at this point in the command string.
