Thank you, Josh, for your input.
I've observed the same issue across other APs as well. Interestingly, an EdgeCore EAP101 on the same network did not exhibit any errors or drops. We also have Aruba units deployed at a different location within our intranet, and they too have shown a high number of errors and drops.
The statistics for the one unit I initially mentioned were reset around 11:39 JST, and the values checked at 17:39 JST are as follows:
(Controller) [mynode] #show ap debug radio-stats ap-name AP1 radio 0 | include rror,rop,set
Total Radio Resets 0
Resets Beacon Fail 0
Tx Frames Dropped 666

Tx Bcast Frames Dropped 0

Would you agree that these results could be indicative of a performance issue?

No, this is not normal. I would check a few more APs to see if you can spot a pattern, but you may first want to consider clearing the counters as they are quite high. Clearing the counters will help make it more clear how frequently the errors/drops are incrementing.
clear ap debug radio-stats ap-name <ap-name> radio <id>
show ap debug radio-stats ap-name <ap-name> radio <id> | include rror,rop,set

Hello everyone,
I'm currently managing a network of 100 APs using the Aruba Mobility Controller. Upon inspecting the logs of three randomly selected APs using the command:
show ap debug system-status ap-name [APNAME]
I noticed that the interface counter values, particularly for Rx_errors and Rx_drops, are significantly high. Below is an excerpt from one of the AP's log:
Interface counters
------------------
Interface Rx_pkts Rx_errors Rx drops Tx_pkts Tx_errors Tx_drops Resets
--------- ------- --------- -------- ------- --------- -------- ------
wifi0 494830483 70791350 504029514 776829505 16 4249 0
wifi1 136516651 27629129 142041968 10499851 5 448 0
This pattern of high Rx_errors and Rx_drops seems to be consistent across the three APs I checked.
Is this normal for Aruba devices? Just to clarify, I'm not implementing any policy controls on either the APs or the controller.
Additional information:
- Model: Aruba7205-JP
- Firmware Version: 8.10.0.9 LSR
AP Model: AP-505
I would appreciate any insights or recommendations on this matter. Thank you in advance for your assistance.
Best regards
