Setting Up SNMP Management 51Setting Up SNMPManagementAny network management application running the Simple NetworkManagement Protocol (SNMP) can manage a Switch if:■ The correct Management Information Bases (MIBs) are installed on themanagement workstation.■ The management workstation is connected to the Switch using a portin VLAN 1 (the Default VLAN). By default, all ports on the Switch are inVLAN 1.You can use the 3Com Network Supervisor application that is provided onthe CD-ROM that accompanies your Switch to provide SNMPmanagement for your Switch. If you use 3Com Network Supervisor itautomatically loads the correct MIBs and necessary files onto yourworkstation.Pre-requisites ■ Documentation supplied with the SNMP network managementapplication software.To manage your Switch using an SNMP network managementapplication, you need to specify SNMP community strings for the usersdefined on the Switch. You can do this using the command line interfacesystem management snmp community command — refer to thecommand line interface section of the “Management Interface ReferenceGuide” for more information.Default Users andPasswordsIf you intend to manage the Switch using the web interface or thecommand line interface, or to change the default passwords, you need tolog in with a valid user name and password. The Switch has three defaultuser names, and each user name has a different password and level ofaccess. These default users are listed in Table 9.CAUTION: To protect your Switch from unauthorized access, you mustchange all three default passwords as soon as possible, even if you do notintend to actively manage your Switch
