Spanning-tree problems on N2000 switch

Hello,

on our N2000 Switches i get a lot of log entries with regard to spanning-tree on access ports. An exemplary snipped from one switch looks as follows,

The port has the following configuration,

spanning-tree portfast
switchport access vlan 501


firmware version is 6.3.3.10 and earlier.

How can I eliminate this messages. At least the log is flooded with messages not necessary, but it seems to be a problem for PXE boot and DHCP.


Best regards
