WLC9800 With 10gb port

i installed wlc9800 17.16.01 on esxi8 , with dedicated port 10gb

Cisco core switch read it 10gb

Esxi read it 10gb

cisco wlc 9800 read it 1gb

is that normal with WLC 9800 or i miss something ?

Actually it does not matter. The interfaces will be giga anyway.  If you need more than 1 Giga, you can work with port-channel.

But the overall throughput is much less the 10 Giga.

      Supports up to 2.1 Gbps of throughput in a centralized wireless deployment (low-throughput profile without SR-IOV)

    With a high (enhanced) throughput profile, up to 5 Gbps can be reached on ESXi and KVM with the right set of network cards

On 9800-CL the name GigabitEthernetX is irrelevant because it's a virtual interface to a virtual switch and there is no direct relationship with the physical interface on the server.
"show int" shows  "Hardware is vNIC" and "media type is Virtual" and although it shows "1000Mbps" that has no impact of the rate of traffic through the interface.

> is that normal with WLC 9800 or i miss something ?
That is normal for 9800-CL.  You missed the fact that the 9800-CL is not directly connected to the 10G interface as a physical 9800-80 appliance would be.

 As the interface is GigabitEthernet, the information you see is correct.   

 

WLC#show interfaces gigabitEthernet 1
GigabitEthernet1 is up, line protocol is up
  Hardware is vNIC, address is 0050.56bf.d3c3 (bia 0050.56bf.d3c3)
  MTU 1500 bytes, BW 1000000 Kbit/sec, DLY 10 usec,

 In order to achieve 10Giga the interface should be TenGigabitEthernet

how to make it TenGigabitEthernet and the installation read it 1gb

Which WLC size did you instaled?

thanks alot for your help , but i have another question does wlc9800 support port channel or from coreswitch side !

Now you got me. Thinking better I dont believe you can configure the WLC with port-channel. You can use trunk but not port-channel. 

On this guide we can see that only one interface is given as option for Management

On the following guide they show the configuration for ESXI. See the section "Configuring NIC Teaming on a Virtual Switch"
