Re: Can network manager change MTU?

Hi, Yes it can, but only in cli with nmcli nmcli c con-name.mtu 12345 Cheers, Damian Oct 27, 2023 22:50:35 James Knott <james.knott@jknott.net>:

I've been trying to experiment with jumbo frames.  On my ThinkPad, with MTU set to Automatic, the MTU does not follow what the DHCP server provides.  I have even tried manually setting the value, but that doesn't work either, even when set to something smaller, such as 1492.  Is this an issue with the Network Manager?  Or perhaps a hardware limitation?

I can change MTU in Yast Network Setting on my desktop system.

I'm running openSUSE 15.4 & KDE.

tnx jk
