The device is a NXOS 9.3.5
Nexus 9000 C948GC-FXP
When we try to download the running config via NCM from the device, it fails and displays error: "Unable to login to device: Timeout"
Validation/Troubleshooting Steps:
The Solarwinds Windows box can successfully ping, poll with SNMP, and login via SSH to the device using putty.
Device is pointed to ISE for radius, and Solarwinds for SNMP. Solarwinds IP is entered in the access-class on the vty.
Device has correct source-interface configured, and correct vrf set, for radius and tftp.
When the download is initiated from NCM, ISE shows that the device authenticated successfully with username/password.
The "Generic Cisco Nexus" device template is set, which uses the "management" vrf which is correct.
The device authorization profile in ISE is set to grant the "network-admin" privileges to the account when logging in.
We inspected the Solarwinds Session Trace Log. The Log is showing that the Solarwinds SSH session is being successfully established with the device:
Got login challenge: Password:
Password challenge detected - send password "pw"
State change: Connected
Connected!
Send user name.
Process Login State: Username
Hostname# "username"
Once the session is connected, the device continually sends the username even though Solarwinds already logged in and is presented with the command prompt#. The log shows Solarwinds continually trying to send the username until the session is eventually terminated.
We can't seem to figure out why NCM and tftp are not working with this device.
