Afternoon,
Apologies if this is double posted.
We are currently deploying a new VMWare Environment utilising an HP C Class Blade Chassis, Virtual Connect 10GbE modules, BL680 blades with Flex10 NICs, Nexus 1000V virtual switch and Nexus 5010 switches.
i.e.
Nexus 5010 -> HP VC 10GbE -> Flex10 NIC -> Nexus 1000V Virtual Switch -> VMWare
In Virtual Connect the Flex 10 NICs are divided into two, with a 1000Mbps and 9000Mbps interface on each. These show correctly in VMWare.
We have configured a port profile for the Nexus1000V Uplink to the LAN as follows:
port-profile type ethernet Trunk-Profile
vmware port-group
switchport mode trunk
switchport trunk allowed vlan 2-1200
channel-group auto mode on sub-group cdp
no shutdown
system vlan 1094,1196
state enabled
This comes up just fine, we can connect to VMs on Port Profiles created and everything looks OK. However doing a show int brief shows all interfaces and port channels up at 10Mbps. Initial testing on the VMs suggests the networking is running above gig speeds so this may just be a display bug but I cannot find any mention of this issue anywhere (HP, VMWare and Cisco sites along with copious googling).
My options for forcing the port speed are only 10,1000 and 10000. If I force to 1000 it drops then comes back up at 10. If I try and force 10000 I get an error: Configuration does not match the port capability.
Has anyone seen this before or know what could cause it?
This is what we get if we do a show int brief:

Hi Jeff,
This is a known issue with Nexus 1K and HP Flex-10 deployment. As you observed, this is only limited to
be a CLI display issue and there is no impact on the forwarding bandwidth or functionality. We are
looking to address it in a future release.
Thanks,
Munish.
