8.10(128.101)

Description (partial)

Symptom:
AireOS ME stop externalising data after a DNAC Upgrade

Conditions:
DNAC version Upgrade from Antman 1.3.3.7 to Cyclops[72158]
AireOS ME version -8.10.128.144

I faced this issue today again after Upgrade of DNAC.
After the DNAC came UP, the AireOS-ME was still externalizing data and the status was below, but it was somehow sending for 15 min in an 2 hours.
 
(aireOSME) >show dx summary 
 
Data externalization config...................... Enabled
Data externalization status...................... Enabled
 
After sometime it stopped sending data and I see the status as below.
 
(aireOSME) >show dx summary                
 
Data externalization config...................... Enabled
Data externalization status...................... Disabled
 
For me this is a critical issue for DNAC deployments even though you mentioned that this is Day 1 behaviour and more frequent for AireOS-ME.
I have faced this in 2 Upgrades in last 1 month, so not really a corner case.

For the same time AireOS -5520 started externalizing the data and not issues were seen.
