NSO FMC - device connectivity failure

Hello Team,

 

NSO 4.6.2 with NED for FMC: ncs-4.6.2-cisco-fmc-1.0.6.signed.bin

 

Installed successfully, show packeges show the right data.

 

Device (FMC) added:

But sync up failing:

Logs in /var/log/ + Packet captures confirms it;'s trying plain http over tcp/443 instead https (and of course FMC rejects such a request):

So why is that happening ? Is there any command under the device forcing SSL for tcp/443 ?
Should not NED force this ? (it's not possible to connect via plain http anyway).

Once i get thru this: there might be a problem with cert ? Can i somehow accept it ?

Thanks,
Michal

Hi Michal,

 

There are some NED settings for this:

 

admin@ncs(config)# devices device fmc0 ned-settings cisco-fmc-connection ssl ?
Possible completions:
  accept-any    Accept any certificate (unsafe)
  certificate   Use specific DER formated SSL certificate

I think either of these will make it use SSL. If you set accept-any, this will also solve your second problem (but only use it for development and testing).
