I have a few hundred devices added that NCM is unable to grab the configs for, I have a list of all devices I was able to grabwith the following SQL:
select * from Nodes where LoginStatus like '%Refused%'
I've determined fixing this is as simple as setting "Request Configs Using:" and "Transfer Configs Using:" to TELNET.
My question is is it safe to update the CommandProtocol and TransferProtocol fields in the Nodes table directly?
