Hi
Mike,
thank you very much for your reply. I did "confirm"
strange behavior of Cisco device and opened TAC case. It seems to it
has a trouble to response on very specific (full) OID. Sorry I didn't
noticed earlier.

Device types detected by snmp Oids.
Different Oids for
different OS types, but mostly is sysObjectId and sysDescr.
And
exactly for Cisco IOS (XR, XS) used sysDescr.
When device discovery
not received sysDescr than os type resets to generic os.
Try
increase SNMP timeout, I sure this should fix your trouble.

Mike,
I'll try to extend timeouts, but not sure about bug
in IOS version. Is it possible to configure device type manually? How
is the device type detected? Is it from SNMP MIB?

Hi,
seems
as device
have some troubles with snmp access (ie network timeouts).
This
is indicated by the fact that sysDescr periodically lost.Increase
snmp timeout in device edit page to 2-3 sec.
Another way - update
firmware to latest (not sure, but can be firmware issue).

Hi all,
I would like to ask for a hint or information
I'm missing in oder to successfully monitor Cisco ASR9K (ASR9901-RP)
running Cisco IOS XR Software, Version 7.0.1.
I'm
getting "Generic device" not Cisco device and for unknown reason I'm
getting this LOG messages
..
SNMP
works just fine, as other graphs or values are being collected
successfully. There is no error in observium.log and polling graphs
looks good too.
On top of that, every full
discovery cycle (every 12 hours) we are getting full set of alarms from
this device.
Any idea please? Thank you Marian
