Product and Software: This article applies to all Aruba controllers and ArubaOS 3.x.
On the SNMP server, when you upload the aruba-mon MIB and try to poll this MIB OID "22.214.171.124.4.1.148126.96.36.199.188.8.131.52.1.5", the following error is shown:
"No Such Instance currently exists at this OID"
For the WLSX-MON-MIB::monAPInfoRSSI MIB to work, there should be monitored APs entries detected by an active AP.
Issue the following command and verify that there are monitored APs detected:
show ap monitor ap-list ap-name <name of the AP>
When you execute this command, if you see monitored access points and you try to poll the specific OID information, it will be successful.
The screenshot of "184.108.40.206.4.1.148220.127.116.11.18.104.22.168.1.5" is shown for your reference.
