I found this online when looking at the patches being installed on vShpere and saw this. If you plan on using the Nexus stuff, please read.
vCenter Update Manager does not list patches or updates for Cisco Nexus 1000V by default. This knowledge base article provides the procedure for adding a Cisco Nexus 1000V patch source to vCenter Update Manager.
See KB Article: 1013134 on how to add the Cisco Nexus Patch info into update manager.
