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

— sequentially aged from the top of the Address Aging table to the bottom of

the table

•

Random local addresses
