Re: Cisco 4006 Error Message...

It basicaly means your devices has received an invalid mac address (all zeros) which can be caused from numerous things including a device with faulty nic, misconfigured server or traffic generating devices such as Smartbits etc. cisco's common catos error message link is quite good.
