Hey Jay,
I am pretty sure I that I have seen this as well some time ago. Not sure what it the problem was but I do know my configuration was correct so I just moved on Not sure if this helps From: [email protected] [mailto:[email protected]] On Behalf Of Jay Taylor Sent: November-13-10 11:28 AM To: CCIE OSL Subject: [OSL | CCIE_RS] Proctorlabs hardware issue? I'm having an issue where whichever port I add last to an etherchannel between Cat1 and Cat2 will continually bounce. Configuration looks correct; is this a hardware issue?
