Address Aging
You can set the per-port aging value using the Address Aging menu. The following
describes the types of address aging.
There are two types of aging:
•
Port aging
— Any address in a port's address table that has not been active for a port's
configured aging time will be removed from the port’s table
— Set at the Port Address Table Aging menu
•
Master Table aging
— Addresses that are in the master address table, but not in any port address
table, will be removed from the master address table after the system aging
time
— Set at the Master Address Table Aging menu
There are two levels to set for the port and master aging tables:
Time Interval Aging is a time limit, in minutes, which will drop older addresses
after the selected time.
Automatic On-Demand Aging stores addresses until reaching maximum capacity of
the table, then deletes addresses, (in the following specific order) down to a selected
percentage level and continues to cycle in the same manner.
•
Random remote addresses
•
Sequential remote addresses

the table
