Setting Up SNMP Management 51 Setting Up SNMP Management 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 Supervisor application that is provided on the CD-ROM that accompanies your Switch to provide SNMP management for your Switch. If you use 3Com Network Supervisor it automatically loads the correct MIBs and necessary files onto your workstation. Pre-requisites ■ Documentation supplied with the SNMP network management application software. 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 "Management Interface Reference Guide" for more information. Default Users and Passwords If you intend to manage the Switch using the web interface or the command 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 9. CAUTION: To protect your Switch from unauthorized access, you must change all three default passwords as soon as possible, even if you do not intend to actively manage your Switch
