I am having an issue at one of our remote agencies whereas we are getting numerous mac-flap notifications on our switches. This has become kind of a hinderance as we are getting tired of seeing these messages. The end users havent been complaining, but the log messages are annoying.
It's usually occurring with the same mac-addresses over and over. Upon further investigation, we found the mac-addresses are all on laptops which have both wireless and wired nic's. There are wireless AP's (cisco 1242's) in use which they can connect. We also found where the error is popping up as they move from wireless into docking into their docking station which has a lan cable attached. I was under the assumption that the wireless mac and wired mac were different numbers and therefore if the wired was up simultaneously with the wired, as it switched over, they shouldn't get a flap.
How can I correct this....or is it correctable?
I have attached a diagram to show my scenario, keep in mind those are just a few of the MANY msg's we have been receiving. If anyone
can explain this to me, I'd appreciate it.
