HowTo create vif with mtusize 9000

skellner — Thu, 05 Jun 2025 06:18:10 GMT

I'm trying to create a vif consisting of two interfaces e1a and e2a. After creating the vif with New-NaNetVif it has always an mtusize of 1500 per default. The only way I found how to set mtusize is with set-nanetinterface -mtusize 9000. However, it always throws MTU size must be between 296 and 1500 for vif.

Thanks in advance

Stefan

Stefan,

Somethings seems off here

whats the name of your vif, for example vif10g

$int = get-nanetinterface vif10g

$int | gm (gives you all the properties)

But you should be able to do something as simple as

get-nanetinterface vif10g | Set-nanetinterface vif10g -mtusize 9000 -confirm -verbose

Don't know what was the problem the first time. Meanwhile I got it to work for example like this

Set-NaNetInterface vif11-487 -Address x.x.x.x -Netmask 255.255.255.0 -Mtusize 9000 -partner ...

In Advance I did a New-NaNetVif vif11 e1a e2a and Add-NaVlan vif11 487
