This is good to do early so that when you apply switchport parameters to the Port-channel interface it automagically applies them to the GigabigEthernet interfaces. EtherChannel is a port link aggregation technology or port-channel architecture used primarily on Cisco switches.

Daniel Cave September 15, The other is increase in network reliability as a coupled Ethernet link is able to survive individual link failures. I do this on my laptop, so network scripts manage the bridge and wired connection, but I can still use wifi from the ethercnannel interface. You can assign multiple IP addresses using interface aliases which would look something like this: There are a few basic things that you should know about EtherChannel: By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Of course, you would always want to see the results of your configuration. bondung


Want to learn more about router and switch management? Once the ports have been configured a Port channel logical interface will be automatically created. April 24th, at 9: Very clear and easy ethefchannel follow. In order to verify if the configuration is correct, enter the following to view the ports that have been assigned to the port-channel.

How to Setup Linux Etherchannel Bonding for Network Interface HA

This is where an EtherChannel is most desirable, it allows use of all available links between two devices. From Wikipedia, the free encyclopedia. Server Fault works best with JavaScript enabled. I want to connect a CentOS 6.

If this is right, you’ll be able bondingg either show etherchannel 2 detail or show lacp internal on the switch, the flags on the Channel Group will probably say SA Slow Active. Let’s look at a sample of a typical EtherChannel configuration using load distribution and forwarding methods. 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.

How to Setup Linux Etherchannel Bonding for Network Interface HA

If you still do not see the link then the interface is not eyherchannel to the switch. Without the use of an EtherChannel, STP would effectively shutdown any redundant links between switches until one connection goes down. I have a question.


Hope that helps [ Reply ]. Verify that ethsrchannel will still be able to login to the machine using the same IP or Hostname.

I have 2 dell servers with double 10 ports in bonding bondinng 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. Also ensure you are able to connect the server using the IP address. In Linux this is called bonding, in switches its commonly referred to as a port channel.

Sign up using Facebook. The server I have connected on the other side, is connected via 10 gig fiber. Everything is very open with a vey clear explanation of the issues.
