Enabling SNMP Management Access
The switch can be configured to accept management commands from Simple
Network Management Protocol (SNMP) applications. You can configure the switch
to (1) respond to SNMP requests or (2) generate SNMP traps.
When SNMP management stations send requests to the switch (either to return
information or to set a parameter), the switch provides the requested data or sets the
specified parameter. The switch can also be configured to send information to
SNMP managers (without being requested by the managers) through trap
messages, which inform the manager that certain events have occurred.
Community Strings
Community strings are used to control management access to SNMP stations, as
well as to authorize SNMP stations to receive trap messages from the switch. You
therefore need to assign community strings to specified users or user groups, and
set the access level.
The default strings are:
• public - Specifies read-only access. Authorized management stations are only
able to retrieve MIB objects.
