EtherChannel technology is another way for you to increase the bandwidth of your core network links and provide redundancy of LAN links. EtherChannel is primarily used in the backbone networkbut can also be used to connect end etherchsnnel machines.
LACP – How to Configure Network Bonding in Linux – Backdrift Backdrift
This is where an EtherChannel is most desirable, it etherfhannel use of all available links between two devices. On the Linux side, the configuration looks like this: And since your Fast Ethernet links are now combined into one channel, it allows for redundancy, in case one of the links goes down.
Wow, Again i am here and your awesome blog.
May etherchannfl, at Of course, you would always want to see the results of your configuration. July 9th, at EtherChannel technology was invented by Kalpana Nath in the early s. I want to connect a CentOS 6.

Read more about Ramesh Natarajan and the blog. You can assign multiple IP addresses using interface aliases which would look something like this:.
The two Cisco Nexus switches involved in a VPC differ from stacking or VSS technology in that stacking and VSS create a single data and control plane across the multiple switches, whereas VPC creates a single data plane across the two Nexus switches while keeping the two control planes separate.
This makes it very resilient and desirable for mission-critical applications. Use this Contact Form to get in touch me with your comments, questions or suggestions about this site. In order to create a bonded link, each interface of the bond will need to be setup with the identical configuration. Approx half of the network hosts can ping and ssh the Linux box, whereas the other half cannot. Additional docs on linux bonding driver https: Mail will not be published required.
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.
SW config-if speed SW config-if duplex full. LACP is referred to in linux as bonding mode 4, so we need to inform the kernel module to use this bonding mode.
You can verify that its down by issuing the following:.

Permanently disable it as root in order to make your adapter bonding working properly: To learn more about EtherChannel, please see the official Cisco documentation: Luckily most of this is taken care of automatically by the networking init scripts.
