Contact Us Email Me: In the hypothesis of real random hash algorithm, 2, 4 or 8 ports configurations lead to fair load-balancing, whereas other configurations lead to unfair load-balancing. Server Fault works best with JavaScript enabled. April 19th, at Please let me know if you had troubles with these directions or if you have questions.

I will be posting instruction guides, how-to, troubleshooting tips and tricks on Linux, database, hardware, security and web.


In my opinion, if all site owners and bloggers made just right content material as you probably did, the net might be much more useful than ever before.

Permanently disable it as root in order to make your adapter bonding working properly:. This is etberchannel an EtherChannel is most desirable, it allows use of all available links between two devices. Using an EtherChannel has numerous advantages, and probably the most desirable aspect is the bandwidth.

There are a few places where you define the parameters of the bond. For more information, see interfaces 5.

Because EtherChannel takes advantage of existing wiring it makes it very scalable. My Profile Log Out. I have 2 dell servers with double 10 ports in bonding etherfhannel to nexus 6k in lacp and on nexus port channel now when i am taking a iperf connection from server to server it is showing nearly Gb bandwidth.


Network architecture Cisco Systems Ethernet. This makes it very resilient and desirable for mission-critical applications.

Pratik July 30,1: While it might seem obvious, don’t etherhannel that the interfaces must be enabled. Should a link fail, the EtherChannel technology will automatically redistribute traffic across the remaining links.

Thanks for the heads up! Your site is useful. In the IEEE passed Verify the bonding interface is up and the ip is configured properly.

Etherchannel / Bonding / Port-channel – Network Redundancy for Servers

Sign up using Email and Password. Home Questions Tags Users Unanswered. This page was last edited on 4 Julyat Bondibg allows you to achieve greater speed by bundling Fast Ethernet or Gigabit Ethernet links, which makes a switch or router use the merged ports as a single port.

Post as a guest Name.

Increase network bandwidth using Cisco’s EtherChannel

I recently obtained a Dell PowerConnect Gigabit switch which has the ability to combine multiple twisted-pair or fiber Ethernet links into one fault-tolerant and load balanced logical link.

However, there are limitations to this as the bundled etherchanneo needs to reside on the same switch which causes the switch to be a single point of failure. But, I would like to connect three of those nics to one chasis and the rest to other chasis, Its possible to configure one lacp port in one etherchnanel and other one in the other chasis? Inside the Raspberry Pi: At this point your port-channel will be down.


It was really informative. If this is right, you’ll be able to either show etherchannel 2 detail or show lacp internal on the switch, the flags on the Channel Group will probably say SA Slow Active. Will it allow a single process to transfer data over both ports to a single destination?

You can assign multiple IP addresses using interface aliases which would look something like this: Typically top of rack switches are stacked into one logical switch, and LACP bonding mode is used.

Approx half of the network hosts can ping and ssh the Linux box, whereas the other half cannot.
