MAC Address Continously Flushing:
Issues have been seen in our customer environments where the MAC address table is continuously flushing
because of a layer-2/bridging loop. This causes the hardware to write the MAC address as static in the
hardware.
For dynamic MAC addresses, the STATIC-BIT should always be zero. During a loop condition, the hardware
sets the STATIC-BIT to 1 and sometimes, even after the loop has been recovered, the hardware does not
update the table (i.e STATIC-BIT does not set back to zero).
This may cause the MAC address to be learned on an incorrect port in the hardware which will cause the
traffic to be dropped for that destination.
