Setting Up SNMP Management 51

Setting Up SNMP	Any network management application running the Simple Network
Management	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	If you intend to manage the Switch using the web interface or the
Passwords	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
