Setting Up SNMP Management 49 Web Management Over To manage a switch using the web interface over an IP network: the 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 was 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 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. For a description of 3Com's network management applications, see Appendix C, "3Com Network Management" on page 63. Prerequisites ■ The default read community string is public. The default write community string is private. ■ To display the current configuration of the community strings in the System View, enter display snmp-agent community. ■ To configure new read community strings, enter snmp community read (new community string up to 32 characters). ■ To configure new write community strings, enter snmp community write (new community string up to 32 characters). ■ To remove a community string, enter undo snmp-agent community (the string to be removed). To manage your switch using an SNMP network management application, you need to specify SNMP community strings for the users defined on the switch. You can do this using the command line interface system management snmp community command. Refer to the command line interface section of the "SuperStack 4 Switch Command Reference Guide" for more information. These switches support SNMP V1, V2, and V3. SNMP V3 is on as default. All commands are in snmp menu in System View.

Setting Up SNMP Management

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 was 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:
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
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.
For a description of 3Com’s network management applications, see Appendix C,
“3Com Network Management” on page 63.
Prerequisites
■
The default read community string is public. The default write community
string is private.
■
To display the current configuration of the community strings in the System
View, enter
display snmp-agent community
.
■
To configure new read community strings, enter
snmp community read
(new community string up to 32 characters).
■
To configure new write community strings, enter
snmp community write
(new community string up to 32 characters).
■
To remove a community string, enter
undo snmp-agent community
(the
string to be removed).
To manage your switch using an SNMP network management application, you
need to specify SNMP community strings for the users defined on the switch. You
can do this using the command line interface
system management snmp
community
command. Refer to the command line interface section of the
“SuperStack 4 Switch Command Reference Guide” for more information.
These switches support SNMP V1, V2, and V3. SNMP V3 is on as default. All
