How to change physical interface / LAGG MTU-size?
-
A significant part of my network is 10G. And all my switches do support jumbo frames. So I wonder if I should not enable jumbo frames for at least the 10G-part of my network.
That idea is strengthened by the fact that the transfer speed between PC and NAS, both having NVME SSD's and a fast processor, in opposite to what you would expect do not come close to 10G-transfer speed.
So I changed the MTU size of my NAS-systems to 9000. However the transfer is passing pfSense and the MTU-size is there 1500. So I need to set max MTU to 9000 on pfSense as well.
And I think that pfSense would profit even more than other devices form a bigger packet size, since the number of packets to analyze will be significant lower.
However .... I can not find a setting to change the (maximum) MTU-size !!??
Note that:
- I am using LAGGs in favor of vlan-trunks
- and there is a setting to change the vlan MTU-size
- but of course with a maximum of the underlying interface/ lagg
And there is the problem, no idea how to change the max MTU of the physical interfaces / lagg's? Do I overlook something ?

There's an MTU setting on the Interface pages. However, I have no experience with LAGG, so can't say about there.
