Simple Network Management Protocol (SNMP)
The Exalt radios primarily use a browser-based graphical user interface (GUI) for radio configuration
and management, as described in Exalt Graphical User Interface (GUI)
. In addition, a command line
interface (CLI) is provided for serial and/or Telnet access, as described in Command Line Interface
(CLI). SNMP is often used for management of larger networks as described here. 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.
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.
Exalt 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.
Some Exalt radio models also allow for “legacy” SNMP support for SNMPv1 and SNMPv2.
Configuration of all passwords and community strings is performed from a separate Simple Network
Management Protocol (SNMP) Configuration page.
