Configuring MAC address entries

Configuration guidelines

•
You cannot add a dynamic MAC address entry if a learned entry already exists with a different
outgoing interface for the MAC address.
•
The manually configured static, blackhole, and multiport unicast MAC address entries cannot
survive a reboot if you do not save the configuration. The manually configured dynamic MAC
address entries are lost upon reboot whether or not you save the configuration.
A frame whose source MAC address matches different types of MAC address entries is processed
differently.

Description
Forwards the frame according to the destination MAC address regardless of
whether the frame's ingress interface is the same as that in the entry.
•
Learns the MAC address of the frame and generates a dynamic MAC
address entry, but the generated dynamic MAC address entry does not
take effect.
•
Forwards the frame based on the multiport unicast MAC address entry.
Drops the frame.
•
Learns the MAC address of the frames received on a different interface
from that in the entry and overwrites the original entry.
•
Forwards the frame received on the same interface as that in the entry
and updates the aging timer for the entry.
