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 that 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 switch's IP address)
If you receive an error message, check that your IP information was
entered correctly and that the awitch 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 in the following format:
http://xxx.xxx.xxx.xxx
4 At the login prompt, enter
the password prompt (or the password of your choice if you have already
modified the default password).
5 Click on the Device View to display the Web management options.
Any network management application running the Simple Network
Management Protocol (SNMP) can manage a switch if the management
workstation is connected to the switch using a port on the management
VLAN. By default, the management VLAN is 1, and all ports on the switch
are in VLAN 1.
