DCNM stuck in discovering state

[r.shummoogum]

Hello:

I have installed a new DCNM OVA 10.4 version with a single Nexus 9236

I added the switch in the inventory and when I try to do a discovery, it get stuck in discovering..

Ping works fine bidirectionally

snmp-server user DCNM-XXXX network-operator auth md5 0x54e899652325281c001fb5c14dd8007b priv aes-128 0x54e899652325281c001fb5c14dd8007b localizedkey
snmp-server user DCNM-XXXX network-admin

Logging level set to 6

logging event link-status enable
logging event trunk-status enable

SNMP timeout on DCNM set to 400000 and retries to 2

Any help is greatly appreciated

Thanks

Did you add the license to manage the device?

No. Not yet

I need to be able to discover it first.

I go to Inventory then Discovery

Then I can add the license.

Weird, how are you discovering the switch?

Make sure it can be seen via CDP

After DCNM-LAN discovers a Cisco NX-OS device using CDP, it connects to the device and retrieves information, such as the running configuration of the device. The information collected a

the CDP part works fine

It discovers it thru CDP and then I click add

then the SNMP does to discovering.

I tried on 2 switches and same result

Are these devices being discovered via another seed device?

[r.shummoogum]

Hello:

Both seed and switch mode.

I got it working finally.

I changed the role from Network-admin to vdc admin.

I also configure "no logging level all"

Thanks

I was also going to say that the password on the devices has to be the same as the seed device.

Super happy you finally got it working.

Why the no logging level all. That seems strange.

Can you forward the link to where you found those settings.

Thank you.

Basically, I used the same DCNM to discover a N7K and it worked first shot.

So I compared the config between the N7K and the N9K and I saw the differences in the logging level and the role VDC-ADMIN.

I changed those two parameters and voila.

Thanks
