Hi all,
jumbo frames are supported by Omnia hardware, but I’m unable to set MTU to 9k. I want jumbo frames for LAN enabled. I have set via LUCI 9000 MTU on br-lan interface.
root@someturris:~# grep -B8 9000 /etc/config/network
config interface 'lan’
option ifname 'eth0 eth2’
option force_link '1’
option type 'bridge’
option proto 'static’
option netmask '255.255.0.0’
option ip6assign '60’
option ipaddr 'x.x.x.x’
option mtu ‘9000’
However MTU is at default across all interfaces, physical, or virtual. I have tried to set up larger MTU on eth0/eth2 by ifconfig, but I cant do it for br-lan interface and thus Im stuck on 1500 MTU. Rising MTU to 9000 for eth2 will disconnect everything (LAN/WiFi) and because I dont have console cable, I cant tell You why this happens.
root@someturris:~# ip a | grep 1500
