Prime 2.0 with SW 3850 : Collection error:Wireless Controller inventory collection failed

Unanswered Question

I have lots of SW 3850 which failed on inventory collection with an error:

" Collection Status

Collection Other error: Wireless Controller inventory collection failed.
Status :  Failure to collect feature DCAConfig"

Half of the devices (50 upon 100)  have this error.

Allthoug  Prime can archive  the configuration of all switches..

When I tried to Re-sync the faulty  devices , a few  goes OK:  ( i.e. inventory completed)

I tried to increase the timer ( snmp from 6 sec to 18 sec,   and SSH from 60 to 180 sec) without success.

All the SW 3850 have the same snmp  and tacacs config..

They are not configured as wireless controller.

Could someone help me ?

  • Cisco Employee,

half are working and half are not huh?

Something must be different between them?

Are the ones that are working perhaps configured as wireless controllers?

Thanks for your answer.

Finally, all my 3850 are now in state "inventory completed"

It takes 1 day more to achieve this.

And I changed nothing in the configuration !

So I do not know why it takes so long ?

Perhaps , if the collection use SSH credential, it goes to timeout  because the tacas-server was responding slowly.

Or perhaps, because the 3850 are stacked ( 4 or more switch in a stack) , this could explian why it takes so long..
