When i check it on 4500 or 6500 series, etherchannel default on source-dest-ip load-balancing.
for this OEQ question, i think if traffic is destined for a router, then a better load-balance type will be based one source traffic. Whether it's source mac or source ip. Because if we use load-balance based on destination, it will use the same link/port over and over. for the scenario from Marko, default load-balance will be based on the switch devices itself. Which port will be used first, i still can't find the reference. But we can test it out, on the Switch Processor console by emulating traffic form certain IP/MAC to other IP/MAC Sources : http://www.ciscosystems.com/en/US/tech/tk389/tk213/technologies_tech_not e09186a0080094714.shtml#cat6k Just my 2 cents.. :) Regards, Dani A. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Marko Milivojevic Sent: 06 April 2010 23:20 To: Patrice Ngassam Cc: [email protected] Subject: Re: [OSL | CCIE_RS] OEQ question 7 On Tue, Apr 6, 2010 at 16:02, Patrice Ngassam <[email protected]> wrote: > the first link to be added into the port channel. Are you sure about that? How does the load sharing algorithm work for EtherChannels? -- Marko Milivojevic - CCIE #18427 Senior Technical Instructor - IPexpert YES!
