Switches store the addresses for all known devices. This information is
used to pass traffic directly between the inbound and outbound ports. All
the addresses learned by monitoring traffic are stored in the dynamic
address table. You can also manually configure static addresses that are
bound to a specific port.
This chapter describes the following topics:
u
MAC Address Learning – Enables or disables address learning on an
interface.
u
Static MAC Addresses – Configures static entries in the address table.
u
Address Aging Time – Sets timeout for dynamically learned entries.
u
Dynamic Address Cache – Shows dynamic entries in the address table.

When MAC address learning is disabled, the switch immediately stops
learning new MAC addresses on the specified interface. Only incoming
traffic with source addresses stored in the static address table (see
"Setting Static Addresses" on page 207 ) will be accepted as authorized
to access the network through that interface.
u
Dynamic addresses stored in the address table when MAC address
learning is disabled are flushed from the system, and no dynamic
addresses are subsequently learned until MAC address learning has
been re-enabled. Any device not listed in the static address table that
attempts to use the interface after MAC learning has been disabled will
be prevented from accessing the switch.
