Managing the MAC Address Table
The MAC address table contains address information that the switch uses to forward traffic between
ports. All MAC addresses in the address table are associated with one or more ports. The address table
includes these types of addresses:
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 address that does not age and that is not lost when the
switch resets.
The address table lists the destination MAC address, the associated VLAN ID, and port number
associated with the address and the type (static or dynamic).
Note For complete syntax and usage information for the commands used in this section, see the command
reference for this release.
These sections contain this configuration information:
