Bond two network ports together, links to the switch (example for clonfarm21)
nmcli connection add type bond con-name enp_bond ifname enp_bond bond.options mode=802.3ad nmcli connection add type ethernet ifname ens7np0 master enp_bond nmcli connection add type ethernet ifname ens2np0 master enp_bond nmcli connection show
Last command will show follwoing:
NAME UUID TYPE DEVICE enp_bond 969dc408-bb43-49e0-8c29-62965f70f4c7 bond enp_bond ens10f0 f333ab08-b67a-41c9-9108-7658af3435d0 ethernet ens10f0 ens2np0 85e7f4bd-5daf-3095-b207-bdcaf14d903c ethernet ens2np0 ens7np0 5abd79b1-22e9-4210-9262-fc2dbbda51f7 ethernet ens7np0 lo bcf93a26-5114-45c5-b586-9288dfefbb33 loopback lo bond-slave-ens2np0 7961787a-f51f-459d-9bf8-0add8a528679 ethernet -- bond-slave-ens7np0 aa376ad3-fd9f-44a2-8154-04685ce2da72 ethernet -- ens10f1 0c14d2dd-c3bc-4d3d-8c7d-04cded521498 ethernet -- usb0 4fef7067-fb03-4115-ac62-c95a91979384 ethernet --
Now, set bond method to 'manual', and set IP address:
nmcli connection modify enp_bond ipv4.method manual ipv4.address 129.57.69.11/24
Set Routing if needed.
You can use 'nmtui' as well to program all above.
Finally, disactivate both ens2np0 and ens7np0, and activate enp_bond; using 'nmtui', or command 'nmcli connection down/up <connection>'.
NOTE: in our case, enp_bond inheritate mac from ens2np0, but IP from ens7np0; only ens7np0 was registered on jnet.
To delete bond, run following command:
nmcli connection delete enp_bond
Bond two network ports together, links to Maroc electronics (example for clondaq10)
nmcli connection add type bond con-name enp_bond ifname enp_bond bond.options mode=balance-broadcast nmcli connection add type ethernet ifname enp0s20u5 master enp_bond nmcli connection add type ethernet ifname enp0s20u6 master enp_bond nmcli connection show nmcli connection modify enp_bond ipv4.method manual ipv4.address 192.168.0.2/24
Deactivate individual ports and activate bond:
nmcli connection down localport0 nmcli connection down localport1 nmcli connection up enp_bond
NOTE: localport0 etc are profile names as it is shown in nmtui, and NOT a device names like enp0s20u5 etc.
nmtui screen should looks like this:
