Hi Friends

I have a syslog message on my PE router, and we have reviewed the network in search of some loop, but we have not found anything.

Hello Marcelo,

This seems to be a related to the Bug ID : CSCtc67672. Please upgrade the IOS to the latest.

Hi Richard

It seems that the %MAC_MOVE-SP-4-NOTIF message is produced by %PM-3-INVALID_SLOT_PORT message, the question is what is causing of MAC flapping, currently seen in two different vlans, no port information seen, this problems is causing connectivity issues. From research, I found that the "%PM-3-INVALID_SLOT_PORT" messages could be because of mac-addresses moving from one virtual-circuit to another. We need to troubleshoot the cause for mac-address flaps.

Marcelo

Is it a wireless device?

Hi Suni

No, this is a PE router.
