Hi Arne, The error message itself is pretty self-explanatory, you are having too many active STP instances (vlans) on ethernet interfaces. Try pruning the vlans by modifying the allowed vlan list on your trunk ports and remove unnecessary vlans.
You can see the limitations for 4.1(3) release here: http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/configuration_limits/limits_413/Cisco_Nexus_5000_Series_Configuration_Limits_for_Cisco_NX_OS_Release_413_chapter1.html Release 4.1(3) is pretty old and you can increase the scalability and configuration limits by upgrading to a newer release such as 5.0(3) or 5.1(3). I've included the configuration limits for these versions below: http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/configuration_limits/limits_503/nexus_5000_config_limits_503_n2_1.html http://www.cisco.com/en/US/docs/switches/datacenter/nexus5000/sw/configuration_limits/limits_513/nexus_5000_config_limits_513.html Upgrading from 4.1(3) to 5.1(3) will be disruptive, unless you go through some interim versions. More information is in the Release Notes in the "Supported Upgrade and Downgrade Paths" section.
