Introduction
The AT-FH812u and AT-FH824u hub (and the connected stack) is managed
through a direct console or modem connection to the AT-FH801u network
management agent module's serial port, using Telnet to access the hub over the
network, a standard browser to access the Agent Module's embedded web agent,
or with SNMP-based network management software. Once you connect a terminal
or PC to the serial port on the hub, you can perform the following tasks:
❑ Enable/disable any port
❑ Set the communication mode for any port
❑ Configure SNMP parameters
❑ Select RMON options
❑ Configure port security
❑ Display system information or statistics
❑ Download system firmware
❑ Restart the system

The hub includes a menu-dr iven con fig uratio n progr am. T he ASCI I inte rface to t his
program is accessed by making a direc t co nne ction to the serial port on the Agent
Module, or by a Telnet connection to the hub over the network.
This section describes how to access the menu-driven configuration program via:
❑ Onsite connection
— A terminal or workstation connected to the serial port locally on th e
Agent Module.
❑ Modem connection
— A workstation connected to the serial port of a remote via modems.
❑ Telnet connection
— A workstation connected to a remote hub via a Telnet connection
through the network.
It also describes how to access the embedded web agent over the network using
any standard browser, or with network management software or other third-party
mangement software.
Attach a VT100-compatible terminal, or a PC running a terminal emulation
program, to the serial port on the Agent Module. Use the null-modem cable
provided with this package, or a null modem connection that complies with the
wiring assignments shown in the back of this guide.
Connecting a
Modem
When attaching to a PC, mak e the following term inal settings:
❑ Terminal emulation type to VT100
❑ Specify the port used by your PC, for example COM 1~4
❑ Communications to 8 data bits, 1 stop bit, no parity, and 9600 bps (for
initial configuration)
❑ Flow control to none

port, you will need to provide an RS232 cable with a 9-pin connector on one end
and a 25-pin connection on the other end. You do not have to set the modem at
the hub's site, because the hub will automatically configure it to auto-answer
mode.

Making a Telnet
Connection
Connecting for an
In-Band Network
Before you access the hub via an in-band Telnet connection or with a Web
browser, you must first configure it with a valid IP address, subnet mask and
default gateway, using an out-of-band connection or BootP protocol. Once the
hub's IP parameters are configured, you can acc ess th e on-board configuration
program from anywhere within the attached network.
Note
Use the Network Configuration menu to specify the maximum number of
simultaneous Telnet connections supported by the system.
The on-board configuration program can be accessed by running Telnet or a web
browser (Internet Explorer
from any computer attached to the network. It can also be managed from a
computer using network manag em ent software. However, prior to acce ssing the
hub (or connected stack), you must first configure it with a valid IP address, subnet
mask, and default gateway using an out-of-band connection or BootP protocol.
The on-board program on ly provides access to basi c configuration func tions. To
access the full range of SNMP mangement functions, you must use SNMP-based
network mangement software.

Parameters Description
IP Address IP address of the agent you are ma naging . Th e Agen t Mod ule sup por ts SN MP over UDP/IP transport
protocol. In this environment, all systems on the Internet, such as network interconnection devices
and any PC accessing the Agent Module, are assigned an IP address. Valid IP addresses consist of
four numbers, from 0 to 255, separated by periods. Anything outside of this format will not be
accepted by the configuration program. (The default address is 0.0.0.0.)
Subnet Mask Subnet mask of the agent you have selected. This mask identifies the host address bits used for
routing to specific submits. (The default subnet mask is 0.0.0.0.)
Default Gateway Gateway used to pass trap messages from the hub's agent to the management station. Note that the
gateway must be defined if the management station is l ocated in a different IP segment. (The default
gateway is 0.0.0.0.)
SLIP IP IP address used to access the configuration program via an out-of-band SLIP connection to the serial
port on the Agent Module.
Bootup IP The default IP address assigned to this agent. This address is used only until you assign a new
address to the agent, or after downloading new firmware to the Agent Module.
Max # of
allowed
The maximum number of Telnet sessions allowed to simultaneously access the Agent Module.

Assigning SNMP
Parameters
Use the SNMP Configuration scre en to display and modify parameters fo r t h e
Simple Network Management Protocol (SNMP). The Agent Module monitors the
hardware status of the hub (or connected stack), as well as the traffic passing
through the ports. A Network Manageme nt St ation (NMS) can access this
information using other th ird-party network managem ent software. Access rights
to the agent are controlled by community strings. To communicate with the agent,
the NMS must first subm it a valid co mmunity st ring for authentica tion. Th e options
for configuring community strings and related trap functions are described in
Figure 5, Figu re 6 and Figure 7, and in Table 4, Table 5 and Table 6:

Changing System
Passwords
The User Passwords screen is used to display or modify user names and passwords
for the on-board configuration program. There are two user types: Administrator
and Guest. Only the Administrator has write access for parameters governing the
SNMP agent. You should, therefore, assign a user name and password to the
Administrator as soon as possible, and store it in a safe place.
Passwords can consist of up to 14 alphanumeric characters and are not case
sensitive. The configuration program will allow a user three attempts at entering a
password before locking the user out by terminating the connection. If for some
reason your password is lost, or you can not gain access to the System
Configuration Program, contact Allied Telesyn tech support fo r assi stance. System
password parameters are defined in Table15.

You can access the hub from anywhere within the attached network. However, you
must first configure the hub with a valid IP address, subnet mask, and default

Telnet), the web agent (with a browser), or the SNMP agent (with network
