Setting Up SNMP Management 49

Web Management Over To manage a switch using the web interface over an IP network: the Network

1Check 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.

2Check 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.

3Open 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

4At 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).

5Click on the Device View button to display the web management options.

Setting Up SNMP

Any network management application running the Simple Network Management

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.
