Introduction
The on-board management agent in the Fast SwitcHub-8mi SNMP provides the switch
with advanced management capabilities. The SwitcHub’s SNMP agent module includes
a menu-driven configuration program that can be accessed by connecting a terminal or
PC to the serial port on the rear panel. You can also access the configuration program
by an in-band Telnet connection, or perform in-band management from any network
management station running SNMP management software (e.g., AccView/Open).
The on-board configuration program allows you to perform the following tasks:
•
Enable/disable any port
•
Set the communication mode for any port
•
Set the switching mode
•
Configure SNMP parameters
•
Configure VLAN port grouping
•
Enable and configure the Spanning Tree Algorithm
•
Restart the system
Making the Connections Required for System Configuration
The SwitcHub provides a menu-driven configuration program. Also the SNMP agent
allows you to manage the switch from any PC attached to the network using in-band
network management software (e.g., AccView/Open).
Note: Limited configuration (i.e., selecting the port transmission mode) and panel
display selection can be carried out with the Configure button on the front panel.
(Refer to the Quick Installation Guide.)
This section describes how to access the menu-driven configuration program via:
•
Onsite connection - A terminal or workstation directly connected to the serial port
on the switch.
•
Modem connection - A workstation connected to a remote SwitcHub via modems.
•
Telnet connection - A workstation connected to a remote SwitcHub via a network
Telnet connection.
It also describes how to access the on-board SNMP agent over the network from a
network management station (NMS) using network management software.
Onsite Connection
Attach a VT100 compatible terminal or a PC running a terminal emulation program to the
serial port on the SwitcHub’s rear panel. Use the null-modem cable provided with the
product package, or use a null modem cable that complies with the wiring assignments
shown in the back of this guide.
When attaching to a PC, set terminal emulation type to VT100, specify the port used by
your PC (i.e., COM 1~4), and then set communications to 8 data bits, 1 stop bit, no
parity, and 9600 bps. Also be sure to set flow control to "none."
Modem Connection
Configure the SwitcHub Site: Connect the switch's DB9 port to the modem's serial port
using standard cabling. For most modems which use a 25-pin port, you will have 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 switch's site, because the
switch will automatically configure it to auto-answer mode.
