The HiveManager and the APs have a call and response check-in system that allows them to confirm that each side of the connection is still responsive; these call and response packets are called echos. There is a specific time window within which an AP would need to respond to an echo to be considered still responsive. If the AP misses a certain number of echos back to back, it is considered disconnected until it responds again. If an AP is still connected to the internet and passing traffic while missing echos, it's likely due to latency on the network; the AP is unable to process the echo request quickly enough due to the amount of traffic it has to process before responding. To confirm that we are missing echo packets, we'd want to SSH in to an AP to enable CAPWAP debugs and then collect tech data. 

CAPWAP debugs:

_debug capwap info

_debug capwap basic

_debug capwap stat

These will be erased if the AP reboots. You can also manually disable these at any time by adding "no" to the start of the command; for example "no _debug capwap info". 

Collecting tech data in HiveManager (formerly NG, cloud.aerohive.com):

Tools> Utilities> Get tech data> Check the box next to the device> Get tech data (blue button at the top of the page this time).

This guide reviews how to get tech data from the CLI of the AP in case that is more convenient:

As you advised we set the email alerts from Hive manager and we started receiving mails. The problem we are facing now is that we are getting many alerts but when we see in hive manager the AP is up since few days and clients are also connected to them and are not facing any network issue. What can be the reason for such alerts? How to fine tune the alerts so that they are genuine?

My apologies, you tagged the post with HiveManager (previously NG), so I assumed. For Classic you would want to go to Home> Administration> HiveManager Services> Check the box next to "Email Service Settings"> Fill in your SMTP server information> Check the box next to "Enable Email Notifications"> Check the boxes for the severity you are interested in along the CAPWAP row of email alert options. Sorry again for the delay here.

We use Hive Manager Classic and there is no silhouette icon in the top right corner.

Please advise
