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 respond to SNMP requests or 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.
The switch includes an SNMP agent that supports SNMP version 1, 2c, and
3 clients. To provide management access for version 1 or 2c clients, you
must specify a community string. The switch provides a default MIB View
(i.e., an SNMPv3 construct) for the default “public” community string that
provides read access to the entire MIB tree, and a default view for the
“private” community string that provides read/write access to the entire
MIB tree. However, you may assign new views to version 1 or 2c
community strings that suit your specific security requirements (see
"Setting SNMPv3 Views" on page 416).
