Default MTU of 1496B in interfaces of VM platforms?

Dear community!

We have couple of VMs deployed in MS hyper-v and I realized that all interfaces have a MTU of 1496 bytes even though no value was configured. Checked this with "show interface XXXX" command

Shouldn´t the interfaces have MTU of 1500 bytes if no value is assigned or for VMs the MTU is different?

Kind Regards!

Hi @Carracido ,

VLAN networks maybe ? Default MTU for VLAN networks is 1496.

Cheers,

Kiwi.
