I have two N5K (5020) switches with NX-OS - 5.0(3)N2(1).
These two switches form VPC domain: peer-link = 2*10Gb ports (1/17-18) and peer-keepalive link over managements ports.
Also I have two HP servers with two 10 Gb ports on each server.
Each server conected by one link to each N5K switch (1/9-10). N5K downlinks configured as access ports with LACP Active mode.
There is only one VLAN (1).
When "no shut" command entered on N5K access ports - ports going in "not connected" status, begin flap and then going in "linkFlapErrDisabled" state.
In attach - "sh run" from N5K.
Please help to troubleshoot this problem.
