Switch memory and invalid source mac address

[elnekramer]

Hi There!

i would llike to know what this error message on my logs mean, also in particular with the "suppressed 719 times"  .  Could this affect memory usage?  if so, how do i clear memory usage on a switch

Hi,

Take a look here:

https://supportforums.cisco.com/document/21056/c4kl2man-6-invalidsourceaddresspacket-error-message-appears-catalyst-4500-series

...trace the MAC address down gi1/43 and find the misconfigured device.

cheers,

Seb.

True, found the mac address, and it seems that it was not a mac address with a valid vendor, problem is,, my switch's memory is still high, and not sure how to dump/clear the memory without rebooting

there is no way to clear or dump the memory. Only possible way is reboot the box.

Your memory allocation being high may be a consequnece of the (valid) configuration you are running on the 4500. Are you seeing any memory related errors in the system log? 

[elnekramer]

the only one is see every now and again is:  addto_mempool_pc_array(): overflow

this is also the memory allocations:
