Nexus 1000V, HP Flex-10 port speeds

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.
