Simple Network Management Protocol (SNMP) Configuration
Use SNMP to manage networked devices and execute the following functions:
•
GET: Obtain information from the device, such as a configuration setting or parameter.
•
SET: Change a configuration setting on the device.
•
TRAP: The device proactively informs the management station of a change of state, usually
used for critical alarms or warnings.
Currently the SNMP implementation does not support TRAP functions. For
critical alarms, use the GET command for specific alarm conditions.
One feature of the SNMP implementation is that system configuration changes do not take effect
using the SET command. Instead, groups of configuration settings can be preconfigured for
global change, and a single ‘Save’ (Commit) command implements all changes.
When some parameters are changed, a link may drop and/or management control lost. MIB files
allow many parameters to be set at once, allowing only a temporarily dropped link or
management control issue. The opposite end radio can be quickly reconfigured, with little
downtime for the link and management control. The save (Commit) command is similar to the
Update button.
Dropped links or management control issues do not occur with every parameter change. Many
configuration changes do not impact traffic or management access.
EX-series radios utilize SNMPv3, a high security version of SNMP, to ensure secure access to
and storing of management data. The SNMPv3 security string matches the admin and user
passwords. Passwords must be eight characters or longer.
Currently not all EX-series radios implement SNMP. Check the software release
notes to verify that the function is available. Generally, the radio supports SNMP
when MIB files are listed on the File Activation Page.
The SNMP MIBs are organized similar to the GUI. Become familiar with the GUI before using
the SNMP function.
