Objects for Monitoring and Control

Management

The Trango SNMP solution supports MIB-II (system only) and the Trango proprietary Management Information Base (MIB). The SNMP agent resides on the AP ONLY. The AP gathers health, status, and performance statistics from all SUs locally, then responds back to the SNMP manager upon request.

Users interested in using the SNMP functionality should review the entire M900S MIB for a complete understanding of its features. The M900S MIB is available for download at:

The following is an overview of a few of the more commonly used SNMP objects in the M900S system.

SU Bandwidth Monitoring

•suEthRXAvgThroughputLog – Average payload data throughput (in Kbits/sec) received on the Ethernet port over the period specified by suStatisticsSamplePeriod (1 ~ 60 minutes).

•suEthTXAvgThroughputLog - Average payload data throughput (in Kbits/sec) transmitted from the Ethernet port over the period specified by suStatisticsSamplePeriod (1 ~ 60 minutes).

•suRFRXAvgThroughputLog - Average payload data throughput (in Kbits/sec) received over the RF link over the period specified by suStatisticsSamplePeriod (1 ~ 60 minutes).

•suRFTXAvgThroughputLog - Average payload data throughput (in Kbits/sec) transmitted over the RF link over the period specified by suStatisticsSamplePeriod (1 ~ 60 minutes).

•suRFInOctets – Number of octets of payload transmitted from the AP’s RF port.

•suRFOutOctets – Number of octets of payload received on the AP’s RF port.

AP Bandwidth Monitoring

•aptrafficEthRXAvgThroughputLog – Average payload data throughput (in Kbits/sec) received on the Ethernet port over the period of 1 minute.

•aptrafficEthTXAvgThroughputLog – Average payload data throughput (in Kbits/sec) transmitted from the Ethernet port over a period of 1 minute.

•aptrafficRFRXAvgThroughputLog – Average payload data throughput (in Kbits/sec) received over the RF link for a period of 1 minute.

•aptrafficRFTXAvgThroughputLog – Average payload data throughput (in Kbits/sec) transmitted over the RF link for the period of 1 minute.

•aptrafficEthInOctets – Number of octets of payload received on the Ethernet port.

•aptrafficEthOutOctets – Number of octets of payload transmitted from the Ethernet port.

•aptrafficRFInOctets – Number of octets of payload received on the RF port.

•aptrafficRFOutOctets – Number of octets of payload transmitted from the RF port.

Link Status Monitoring –Various traps are defined as follows:

•Cold start – when SNMP agent starts running

•Link Up – when the AP enters Opmode “ON”

•Link Down – when the AP reboots

•SU Link Up – when SU associates to the AP

•SU Link Down – when SU disassociates from the AP

•“AP” Opmode Failure – when AP fails to enter Opmode “ON”

AP and SU Control – SNMP also provides several control capabilities. The majority of the features available on the CLI are also available via SNMP. Here are a few of these features:

•Add/delete subscriber

•Change channel

•Set power

•Set radio sensitivity
