Known Extension Problems and Resolutions
Use the following table to troubleshoot and resolve known problems with plug-ins and extensions.
Resolving a Plug-In Conflict
If you see “The specified parameter was not correct,” when Creating a Nexus 1000V plug-in on vCenter
Server, you have tried to register a plug-in that is already registered.
Use the following procedure to resolve this problem.
Step 1 Make sure that you are using the correct cisco_nexus1000v_extension.xml file.
Step 2 Make sure that you have refreshed your browser because it caches this file and unless refreshed it might
cache obsolete content with the same filename.
Step 3 Follow the steps described in the “Verifying Extension Keys” section on page 3-8 to compare the
extension key installed on the VSM with the plug-in installed on the vCenter Server.
