Web Management Over
the Network
To manage a switch using the web interface over an IP network:
1
Check that you have the IP protocol correctly installed on your management
workstation. You can check this by trying to browse the World Wide Web. If you
can browse, the IP protocol is installed.
2
Check you can communicate with the switch by entering a
ping
command at the
DOS prompt in the following format:
c:\ ping xxx.xxx.xxx.xxx
(where xxx.xxx.xxx.xxx is the IP address of the switch)
If you get an error message, check that your IP information has been entered
correctly and the switch is powered up.
3
Open your web browser and enter the IP address of the switch that you wish to
manage in the URL locator, for example, in the following format:
http://xxx.xxx.xxx.xxx
4
At the login and password prompts, enter
admin
as your user name and press
Return at the password prompt (or the password of your choice if you have
already modified the default passwords).
5
Click on the
Device View
button to display the web management options.
Setting Up SNMP
Management V1 or V2
Any network management application running the Simple Network Management
Protocol (SNMP) can manage a switch if:
■
The correct Management Information Bases (MIBs) are installed on the
management workstation.
■
The management workstation is connected to the switch using a port in VLAN
1 (the Default VLAN). By default, all ports on the switch are in VLAN 1.
You can use the 3Com Network Director application that is available from the
3Com website to provide SNMP management for your switch. If you use 3Com
Network Director it automatically loads the correct MIBs and necessary files onto
your workstation.
