Enabling SNMP Management Access
The switch can be configured to accept management commands from
Simple Network Management Protocol (SNMP) applications such as SMC
EliteView. 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.
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 page
3-65).
Community Strings (for SNMP version 1 and 2c clients)
Community strings are used to control management access to SNMP
version 1 and 2c 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, and set the access level.
The default strings are:
•
public - Specifies read-only access. Authorized management stations
are only able to retrieve MIB objects.
• private - Specifies read-write access. Authorized management stations
are able to both retrieve and modify MIB objects.
