SNMP - Diagnostic objects and Notifications
Introduction
The Q data radio’s SNMP Interface supports:
• Supports RFC1213 (Unit name, Unit Location, Firmware, Uptime, etc). Details about RFC1213 and the SNMP
parameters included in this standard can be found in this link : http://www.ietf.org/rfc/rfc1213.txt
• Supports Radio and Ethernet Diagnostics (as seen in the HTML Diagnostics overview)
• SNMP V1 & V2c
• SNMP notifications which include traps and informs
MIB Files
Distributed with the Q data radio firmware are two MIB files which provide structure definitions for the SNMP objects. The
MIB files are suitable for importation into most common SNMP browsers. Definitions for each SNMP object are noted as
comments in the MIB files. Only a summary of each object is noted in this user manual.
SNMP user alarm detection
The Trio Q data radio range can detect a number of SNMP alarms which have been raised due to varying radio diagnostic
values. These diagnostic values include:
•VSWR
•Supply Voltage
•Temperature
•RSSI
•Transmit Power
Each SNMP alarm for the diagnostic values shown above, has a maximum of three alarm states. Each one is also represented
with a status number. The alarm states and corresponding numbers are as follows:
•Normal state - 1: The ‘Normal’ state will be displayed within an alarm when a diagnostics parameter is operating
within normal limits.
•User alarm state - 2: A ‘User alarm’ state will be displayed when a diagnostics parameter within the Q data radio falls
outside of the user defined alarm limits. User limits are configurable within the Q data radio.
•Critical alarm state- 3: A ‘Critical alarm’ state will be displayed when a diagnostics parameter within the Q data radio
falls outside of the unit’s hardware specification.
SNMP critical alarm detection
The Trio Q data radio range can detect a number of SNMP alarms which have been raised due to the operational state of the
radio. These operational states include:
•Transmitter PLL locked
•Receiver PLL locked
•Operational alarm detected
•Fan alarm detected (QB, QP & QH only)
Each SNMP alarm for the operational states shown above, has a maximum of two alarm states. Each one is also represented
with a status number. The alarm states and corresponding numbers are as follows:
•Yes state - 1: The ‘Yes’ state will be displayed if the corresponding operational state is active/true.
•No state - 2: The ‘No’ state will be displayed if the corresponding operational state is inactive/false.
Notifications
SNMP notifications are unsolicited SNMP messages designed to inform a user when an SNMP alarm state change has been
detected. The Q data radio range supports two types of notifications:
•Traps: are low bandwidth consuming UDP notifications that have no requirement for a response. If the message is lost
along the way to the destination IP address, the message will be lost.
•Informs: are essentially traps, that require a response from the destination IP address once a notification has been
sent. This gives informs more reliability getting to a destination as the Q data radio range supports retries and time
out periods.
