My Logfile on Nexus 6K is fiilled with Logs like below:

Nexus Version is: 7.0(3)N1(1)

Cisco's document does not explain what is causing this:

Error Message:     AM-3-MAC_REG_FAILED Format: Mac registration with L2FM failed for mac %s, iod %s, phy iod: %s
Explanation    MAC registration with L2FM failed.
Recommended Action    No action is required.

Here is my Logging Configuration:


logging level aaa 5
logging level cdp 6
logging level copp 6
logging level flogi 5
logging level hsrp 6
logging level interface-vlan 5
logging level lldp 5
logging level monitor 6
logging level radius 5
logging level session-mgr 6
logging level spanning-tree 6
logging level track 6
logging level virtual-service 2
logging level igmp 3
logging event link-status default
logging logfile messages 6
logging server x.x.x.x use-vrf x facility syslog
logging monitor 6

Can anyone tell me what are these and how to stop them from occurring. Also would appreciate suggestions on how can I improve logging configuration.
