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 
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
