  • How To Do Linux Network Bonding Teaming in Mint Debian Ubuntu

    Bonding is an excellent way to get both increased redundancy and throughput. It is similar to the "Network Teaming" feature in Windows. There are a few different modes but we will use mode 6, I think it's the best of both worlds, as it is not just a failover, but it provides round robin, so you will get redundancy and load balancing. So if you have a 1G single port, you will have a combined throughput of 4G at this point. Just bear in mind that the true thr........

  • Cisco Router Setup Guide and Tutorial Howto With Commands and Examples

    In most of the Cisco router IOS I find the ports like ge0/0 ge0/1 and ge0/2 or whatever your ports are down. They will not even give you a link light.

  • Debian/Ubuntu/Mint Linux How To Set VLAN in /etc/network/interfaces

    You can find many ways to specify the VLANin your network configuration but Ifind this is the simplest and quickest. In this case we are talking about a bridged adapter "vmbr0" but it works even if you just had a normal non-bridged interface. The key here is that in vmbr0 you'll notice there is no IP address.
