Pratik July 30, , 1: Happy 6th Birthday to The Geek Stuff. Just figure out which ports you want to use for your bond and enable LACP on them. Typically top of rack switches are stacked into one logical switch, and LACP bonding mode is used. But does anyone know what’s wrong here? In Linux this is called bonding, in switches its commonly referred to as a port channel. My focus is to write articles that will either teach you or help you resolve a problem.

This makes the EtherChannel transparent to network applications and users because they only see the one logical connection; they have no knowledge of the individual links.
The hash function gives a number between 0 and 7, and the following table shows how the 8 numbers are distributed among the 2 to 8 physical ports. Pratik July 30,1: In Linux this is called bonding, in switches its commonly referred to as a port channel. All interfaces using EtherChannel must be set up with the same speeds and duplex modes. The Dell switch configuration is surprisingly easy.
For more information, see interfaces 5. Hi, Very nice article i sent it to my students… thanks. From Wikipedia, the free encyclopedia. Using an EtherChannel has numerous advantages, and probably the most desirable aspect is the bandwidth. April 24th, at 9: To overcome this scenario, Cisco switches are stacked to form one logical switch so that ports from the bundle can be evenly distributed across the switches to mitigate effects of a single switch failure.
To learn more about EtherChannel, please see the official Cisco documentation: This automatic recovery takes less than one second and is transparent to network applications and the end user. I will be posting instruction guides, how-to, troubleshooting tips and tricks on Linux, database, hardware, security and web.

How to Setup Linux Etherchannel Bonding for Network Interface HA
I have 2 dell servers with double 10 ports in bonding connected to nexus 6k in etherchabnel and on nexus port channel now when i am taking a iperf connection from server to server it is showing nearly Gb bandwidth.
The etherchahnel module defies the protocol, frequency and other attributes of the low-level bond channel configuration. Sign up or log in Sign up using Google. Of course the upstream network switching and routing gear would need to support jumbo frames as well.

Finally the network address configuration is handled by ifconfig, consistent with most other network interfaces in Linux. While it might seem obvious, don’t forget that the interfaces must be enabled.
Should a link fail, the EtherChannel ethechannel will automatically redistribute traffic across the remaining links.
EtherChannel aggregates the traffic across all the available active ports in ethercannel channel. July 9th, at Support Us Support this blog by purchasing one of my ebooks. Let’s look at a sample of a typical EtherChannel configuration using load distribution and forwarding methods.
If you still do not see the link then the interface is not connected to the switch. Tapas Mallick September 22,4: Because EtherChannel takes advantage of existing wiring it makes it very scalable. Luckily most of this is taken care of automatically by the networking init scripts.
Setting up adapter bonding or in Cisco speech EtherChannel shouldn’t be that hard. This fixed an issue on my box where bond0 was created but none of the slaves would attach to the bond interface. If you do a show lacp neigh you’ll probably see F on the Linux end Fast. It can be used at all levels of the network to create higher bandwidth links as the traffic needs of the network increase. This is where an EtherChannel is most desirable, it allows use of all available links between two devices.
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.
