50CHAPTER 3: SETTING UP FOR MANAGEMENT

Setting Up SNMP Management V1 or V2

Prerequisites

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.

■Documentation supplied with the SNMP network management application software.

The default read community string is public. To change this setting in System View, enter display snmp community.

The default write community string is private. To change this setting in System View, enter display snmp community.

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.

SNMP V3 is on as default. All commands are in snmp menu in System View.

Default Users and If you intend to manage the Switch using the web interface or the

Passwordscommand line interface, or to change the default passwords, you need to log in with a valid user name and password. The Switch has three default user names, and each user name has a different password and level of access. These default users are listed in Table 10.
