Enabling Jumbo Frames per Interface or Vlan on 9400

[mumbles202]

Is there a way to enable jumbo frames on a per interface or per vlan basis on the Catalyst 9400 like you can on a N7K? I know you can enable it system wide, but wanted to see if possible to limit it to a single vlan.

Hi @mumbles202 ,

According to this guide, it is not possible:

Restrictions for System MTU

When configuring the system MTU values, follow these guidelines:

• The device does not support the MTU on a per-interface basis.

I leave the link of the guide:

I hope it's useful for you

Thanks for confirming. That's what I had come to find but was hoping perhaps I might have missed something.
