I can't add any Nexus devices that we just installed on CiscoWorks 3.1 ? Is there any patch that I need to install to get this working and where are located.
CiscoWorks 3.1 is over 3 years old (End-of-Sales December 2009) and is now end of support. It had very limited support for Nexus devices - most of the current Nexus gear was released after development stopped on CiscoWorks 3.1.
