Dynamic Address Configuration
Use the Dynamic Addresses screen to set the amount of time to keep a learned MAC 
address entry in the forwarding database. The forwarding database contains static entries, 
which are never aged out, and dynamically learned entries, which are removed if they are not 
updated within a given time.
 To configure the dynamic address aging time-out value:
1.  Select Switching > Address Table > Advanced > Dynamic Addresses.
2.  In the Address Aging Timeout field, specify the number of seconds the forwarding database 
should wait before deleting a learned entry that has not been updated. 
Note: IEEE 802.1D recommends a default of 300 seconds, which is the 
factory default value.
3.  Click the Apply button.
Interface The port where this address was learned: that is, this field displays the port 
through which the MAC address can be reached.
Status The status of this entry. The possible values are:
•  Static. The entry was added when a static MAC filter was defined.
•  Learned. The entry was learned by observing the source MAC addresses of 
incoming traffic, and is currently in use.
•  Management. The system MAC address, which is identified with interface c1.
