DESCRIPTION
MAC Address

pairs.
Note: Static MAC addresses do not age out.

MAC Type
Static Mac
- A static MAC address is an address that has been manually entered in
the MAC address table. Static MAC addresses do not age out. When you set up static
MAC address rules, you are setting static MAC addresses for a port. This may reduce
the need for broadcasting. Static MAC address forwarding together with port security
allow only computers in the MAC address table on a port to access the Switch.
Dynamic Mac
- A dynamic MAC address is an address that is learned on a port.
Apart from
Static Mac
and
Dynamic Mac
, you can also select other options, such as
Blackhole Mac
and
Permanent Mac
. They are addresses that was manually entered
in the MAB address table and not age out. When setting up the MAC Address rules to a
port may reduce the need for broadcasting.
