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
