I have NCM installed on a server and its working fine. But I need to move it to a different server. I downloaded the software, installed it, and discovery tool. During it though, it missed several switches on the LAN. I went to add them manually, and when I entered the information, and enter the SNMP information and test it always fails. Just says "test failed". I know its set up on the switch properly, since its working on the other server. From the new server I can also putty to the switch I would like to add.
I have confirmed there are no ACLs on the switch that would prevent access.
Any ideas what is happening?
