Etherchanneling Source vs Destination?

When would you use Destination over the default Source Mac address?

Re: Etherchanneling Source vs Destination?


please allow me to extend your question a bit further to make it even more exciting:

- When would one specify layer 2 (MAC address) parameters to be taken into consideration by the Etherchannel hashing algorithm and when does he go to layer 3 (IP address) and even layer 4 parameters (transport info)?

- How would this affect the resources utilization on the switch (take for example a Catalyst 6509 with SUP2/PFC2/MSFC2)?

- In the case of a Catalyst 3500XL, it only supports the choice between "source" OR "destination" (no way to use both in the algorithm); if it is connected on the other side of the bundle to a Catalyst 6500 using Layer 3/4 information in the hash function, how would this affect the traffic flow on the bundle (personnaly I think one of the links could end up being overutilized with respect to the other links in the bundle)

Hope that someone will be able to help.

I hope you are asking about FEC, because these are my links to help you on that. Maybe they will help?
