nload -i 10000000 -o 10000000 p6p1

netstat -anp | grep <port>

Bond two network ports together (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.

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
