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.
