Enabling Jumbo Frames on RHEL7 with nmcli
Submitted by John on Mon, 2016-04-18 13:18
Use the NetworkManager command-line tool to see your connections:
# nmcli connection show --active
NAME UUID TYPE DEVICE
em1 7bb105a5-f663-4e5b-a8aa-fdeb2a16e1a0 802-3-ethernet em1
View the attributes of a single connection:
# nmcli connection show em1
...
802-3-ethernet.mtu: auto
Change the MTU to your new value (in this example, 9000):
# nmcli connection modify em1 802-3-ethernet.mtu 9000
Check for the change:
# nmcli connection show em1
...
802-3-ethernet.mtu: 9000
