I would like to use SNMP to facilitate aiming a
Node. In order to work on this project, I have setup a Node (LHG
XL HP5) and Sector (5SHPn) for testing purposes.
The following shows the status of my Node:
[herbw@AA7HW-01] >

Based upon the above, I would assume that if I query
the signal strength (.1.3.6.1.4.1.14988.1.1.1.1.1.4.1) using
snmpget, I would obtain a value of approximately -28 (the signal
strength varies a bit from the instantaneous value of -28
reported above). However, although I am able to obtain the SSID
using snmpget, I am unable to obtain the signal strength,
frequency or band:
$ snmpget -c hamwan
192.168.88.1 .1.3.6.1.4.1.14988.1.1.1.1.1.4.1
SNMPv2-SMI::enterprises.14988.1.1.1.1.1.4.1
= INTEGER: 1
$ $ snmpget -c hamwan
192.168.88.1 .1.3.6.1.4.1.14988.1.1.1.1.1.5.1
SNMPv2-SMI::enterprises.14988.1.1.1.1.1.5.1
= STRING: "HamWAN"
$ snmpget -c hamwan
192.168.88.1 .1.3.6.1.4.1.14988.1.1.1.1.1.7.1
SNMPv2-SMI::enterprises.14988.1.1.1.1.1.7.1
= INTEGER: 0
$ snmpget -c hamwan
192.168.88.1 .1.3.6.1.4.1.14988.1.1.1.1.1.8.1
SNMPv2-SMI::enterprises.14988.1.1.1.1.1.8.1
= ""
$
Also, is it possible to obtain the Noise Floor (NF),
Signal to Noise Ratio (SNR), or Radio Name from my Node using
SNMP? These are all reported by the /interface wireless scan 0.
Thanks for any assistance you can provide.
Herb, AA7HW
