What is load-balancing EtherChannel?
EtherChannel Load-Balancing Options. EtherChannel load balances traffic across links in the bundle. However, traffic is not necessarily distributed equally among all the links. Frames are forwarded over an EtherChannel link that is based on results of a hashing algorithm.
What is a load-balancing method used in EtherChannel technology?
Depending on the hardware platform, one or more load-balancing methods can be implemented. These methods include source MAC to destination MAC load balancing or source IP to destination IP load balancing, across the physical links. EtherChannel load balances traffic across links in the bundle.
How do I set EtherChannel load balancing?
EtherChannel can use two methods for load balancing Cisco device connections, with the default load balancing based on the source MAC address of the system sending data. But because it is sometimes more important for some data to be received rather than sent, Cisco gives you a choice.
How do I change my EtherChannel load balancing?
To change the load-balancing method for your switch, use port-channel load-balance and verify with show etherchannel load-balance. This is a global command – you can’t change the load balancing method on a per-port or per-EC level. The “XOR” choices balance on source and destination IP or source and destination MAC.
Do port channels load balance?
Traffic in a port channel is distributed across the individual bundled links in a deterministic fashion. However, the load is not necessarily balanced equally across all of the links.
How to verify EtherChannel status and load balancing?
Q3) The same goes for a L3 port-channel -> how do i really verify the different traffic did really flow through different links (other then using “test etherchannel load-balance” ?) and i cant monitor the individual interfaces, their packets are always jumping.

Can you load balance layer 2 EtherChannel by source?
As far as I understand it, when you set up an EtherChannel it will not load balance on all 3 links. Instead it will use up the bandwidth on the first link and then forward the traffic onto the second link and so on. I know that you can load balance layer 2 EtherChannel by source and destination MAC address.
How does ether channel load balancing work on Cat 6K?
In this document you will learn about Ether-channel load balancing on Cat 6K, 7600, 4500, 3750. How it is implemented on this platform? The way EtherChannel load balancing works is that the switch assigns a hash result from 0-7 based on the configured hash method ( load balancing algorithm ) for the type of traffic.
How does EtherChannel balance the traffic across the links?
EtherChannel balances the traffic load across the links in a channel through the reduction of part of the binary pattern that the addresses in the frame form to a numerical value that selects one of the links in the channel.
