I'm having a problem with speed/duplex settings with the Nexus 1000v. I recently upgraded the VSM and VEMs to version 4.2(1)SV2(2.1a) with the VMware hosts on ESXi 5.1. We're now trying to bring an ESXi 5.5 host into the Nexus 1000v and when migrating a NIC I get the following error messages:
2013 Nov 12 13:03:45 sw-ohco01-n1v-1 %ETHPORT-5-SPEED: Interface Ethernet3/2, operational speed changed to auto 10 or 100 Mbps
2013 Nov 12 13:03:45 sw-ohco01-n1v-1 %ETHPORT-5-IF_DUPLEX: Interface Ethernet3/2, operational duplex mode changed to Half
with this showing on a show interface status:
--------------------------------------------------------------------------------
Port Name Status Vlan Duplex Speed Type
--------------------------------------------------------------------------------
Eth3/2 -- up trunk half a-10-10 --
However the ports on the upsteam switch are 10Gb full duplex and these ports work fine when used with the standard VMware vSwitch. I tried setting the speed and duplex in the port profile but get these error messages:
sw-ohco01-n1v-1(config-port-prof)# speed 10000
ERROR: Ethernet3/2: Configuration does not match the port capability.
sw-ohco01-n1v-1(config-port-prof)# duplex full
ERROR: Ethernet3/2: Incompatible Speed and Duplex settings on interface
The other ESXi 5.1 hosts are working fine showing that they are 10Gb full duplex but this 5.5 host is not showing the appropriate speed and duplex and does not appear to be passing traffic. I have verified that the VEM is the same version as the VSM as well:

Any ideas?
