This is my first post and at this stage is research, I run a server that uses a 1gb ethernet port and trunk, the data limit on this is 1TB (either upload or download) a month, i'm doing offsite FTP backups and can see this is daily reaching 13GB. I'm worried this is going to contribute to me breaching my monthly allowance, so I'm considering taking out a second port on a 100MB trunk (which is unmetered) for the FTP traffic specifically.
I'm just not sure how to pass the correct traffic to that port, the physical machine is a Xenserver 7, and the VM that I want to use multiple ports on is Cloudlinux 7 (Centos 7 Variant).
I haven't purchased the cable yet but need to find out if this is possible. I can request that the other cable is on a different subnet to make this easier. I'm not sure what else anyone needs to help me with this.
Thank for you time.
