Management Sessions
You can manage the switch locally or remotely. Local management is
conducted through the Console port on the switch. Remote management
is conducted using Telnet.
Local
Management
To access Command Line Interface (CLI) locally, the switch has a
Console port. To start a local management session, you must connect the
switch to a terminal or a PC with a terminal emulator program using the
management cable.
Note
The initial management session of the switch must be from a local
management session.
Remote
Management
You can manage the switch remotely with the following tools:
Telnet client
HTTP web browser
Before starting an initial remote management session, you must assign a
management IP address to the switch from the local management
session. See “Adding a Management IP Address” on page 28.
Telnet
The switch has a Telnet server that you can use to access CLI remotely
from Telnet clients on your management workstation. Remote Telnet
sessions give you access to the same commands and the same
management functions as local management sessions.
HTTP Web Browser
The switch has a HTTP server. The server is used to remotely manage the
switch over the network with a web browser application. Allied Telesis
supports MS Internet Explorer.
Before starting an initial management session using HTTP, you must
enable the HTTP server on the switch. By default, the HTTP server is
disabled. To start a Web session, see “Starting a Remote Management
Session Using the Web Browser” on page 27.
