Enabling Jumbo Frames on CISCO UCS blades -Hyperv

How to enable Jumbo Frames for Hyper-v hosted on CISCO UCS blades

Jumbo Frames setting can enable from UCS manager and no need to perform any changes from windows end if servers hosted on CISCO UCS blades

You need to make 3 changes:

  • Set the System Class MTU to 9216
  • Create a QoS policy for the MTU
  • Set the vNIC to have 9000 MTU and QoS policy you have created

To configure Jumbo Frames on UCS it is done as a QoS policy and the configuration guide is in the link below:

Whilst you are planning to use Hyper-V as your OS, the following configuration guide is quite useful to understand which components on the UCS you need to configure to enable Jumbo Frames:
