Extreme Networks (Aerohive) AP305C-1 detected as generic device

Help

Hi people,

I am fairly new to this community, so I just start to find my way here.

I just added a few AP305C’s to LibreNMS and some of them are identified as Generic device. I noticed the difference in model type:

iso.3.6.1.2.1.1.1.0 = STRING: “AP305C-1, HiveOS 10.5r4 build-278788”

iso.3.6.1.2.1.1.1.0 = STRING: “AP305C, HiveOS 10.5r5 build-279185”

The AP305C is doing fine within LibreNMS, but the AP305C-1 is identified as Generic. How can I get this solved?

Thanks!

Regards,
Mike

In addition I also am very curious about how LibreNMS discovers and classify the device as the type it is. Then I will probably understand why the 305C is detected as Wireless AP and the 305C-1 as generic. I did not find any templates or files for modification that describe the specific devices.

Any suggestions please?

Thanks!

Mike

Have you checked out:

Could possibly be the following definition, we would have to see the poller output to sure sure though…

Hi Slashdoom,

Thanks for your input, it is really appreciated.

I ran the poller on both the AP305C and the AP305C-1:

AP305C:
./poller.php -h 172.x.x.x
LibreNMS Poller
Starting polling run:

Hostname: 172.x.x.x
Device ID: 17
OS: hiveos-wireless
(output omitted)

AP305C-1:
./poller.php -h 172.x.x.x
LibreNMS Poller
Starting polling run:

Hostname: 172.x.x.x
Device ID: 22
OS: generic
(output omitted)

So if I understand you correctly, the sysDescr_regex should be adjusted to also match the name ‘AP305C-1’?

Mike

I asked Chat GPT to match the expressions:

Therefore, the regular expression /^(Hive)*AP[\w]+(?:_n)?, HiveOS/ successfully matches the input string “AP305C”.

Therefore, the regular expression /^(Hive)*AP[\w]+(?:_n)?, HiveOS/ does not match the input string “AP305C-1”.

So we are getting close :slight_smile:

Damn, I got it! The regex adjusted to also match ‘-1’ and it works now!

Original regex: ‘/^(Hive)*AP[\w]+(?:_n)?, HiveOS/’
Custom regex: ‘/^(Hive)*AP[\w\-]+(?:_n)?, HiveOS/’

Very nice. Credits to Slashdoom for pointing me in the right direction!
