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
"SuperStack 4 Switch Command Reference Guide" for more information.
These switches support SNMP V1, V2, and V3. SNMP V3 is on as default. All
commands are in snmp menu in System View.
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 15.
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.
