An engineer is troubleshooting why a MAC address was not listed in the MAC table and discovers that the VLAN was enabled only on the interface that data is coming in on. Which change fixes this problem?
A. Enable outgoing interfaces.
B. Disable sticky MAC on the access switch.
C. Remove loop detection on interfaces.
D. Flush the MAC address table.
I think B – Disable sticky MAC on the access switch.
A. – MAC learning is only on incoming traffic, nothing to do with outgoing interfaces for the MAC address to be learned
B – sticky MAC will prevent a new MAC being learned
C – loop detection is always a good thing, why remove that?
D – Flushing the MAC address table will only help if the MAC iis already there and they tell us the MAC “was not listed in the MAC table” AT ALL.
