ports. All MAC addresses in the address table are associated with one or more ports. The address table
includes these types of addresses:

The address table lists the destination MAC address, the associated VLAN ID, and port number
associated with the address.

Purpose
Enter global configuration mode.
Specify the login message.
For c, enter the delimiting character of your choice, for example, a pound
sign (#), and press the Return key. The delimiting character signifies the
beginning and end of the banner text. Characters after the ending delimiter
are discarded.
For message, enter a login message up to 255 characters. You cannot use the
delimiting character in the message.
Return to privileged EXEC mode.
Verify your entries.
(Optional) Save your entries in the configuration file.
Dynamic address: a source MAC address that the switch learns and then ages when it is not in use.
Static address: a manually entered unicast or multicast address that does not age and that is not lost
when the switch resets.
