Has anyone seen Duplex MisMatch errors on a N7k with a LAG going to the 5508 WLC? WLC code is 7.0.203.0.
I found a BUG that is private to Cisco ( CSCth11041 ) that looks like it, but I want to make sure.
Any help would be appreciated.

Do you have your N7K ports configured as 1000 Mbps Full Duplex?
How did you find the bug if it is private?
I think only TAC can confirm you about the bug if it is private!
Thanks.

A duplex mismatch is a situation where the switch operates at full duplex and the connected device operates at half duplex or vice versa. The results of a duplex mismatch are extremely slow performance, intermittent connectivity, and loss of connection. Other possible causes of data link errors at full duplex are bad cables, faulty switch ports, or client software or hardware issues.
Resolution : Since for 5500s WLC , data rate is fixed 1k full duplex, please check the switch side data rate , make sure it is set to 1000 Mbps Full Duplex.
