Hi Ben, The discovery/inventory of Servers (iDRAC/Host OS) works with wsman (idrac), snmp (with OMSA agent), wmi (windows without OMSA agent), ssh (linux without OMSA agent). There is very limited use of HTTP protocol in case you have few Dell Networking switches, in that case application launch URL will be http based only. OME 2.1 - User Guide ([URL]   
Hi all, Can anyone tell me if the insecure protocols such as HTTP and TELNET are required for OME? Or are they just listed for legacy support? I'd prefer to only use HTTPS and SSH for my deployment if possible. Any help would be much appreciated! Cheers, Ben Loveday
