Master Address Table Aging Screen
Master Address Table Aging is the aging value of a set time, in minutes, and a set
percentage level after which unused addresses are removed from its table.
➽ Note: If a port address table does not hold enough space for all the needed
addresses, some addresses may be present in the master address table but not in any
port tables. Such addresses will be removed from the master address table after the
master aging time. The addresses will be removed, regardless of whether they have
been seen within that time period. This situation is not very likely, but the function
is a security against remaining unused addresses in the memory for an indefinite
time.
To open this menu from the main menu, select Configuration
→ → → →
Address Aging .
Then select Master Address Table Aging...
The Master Address Table Aging screen contains two main items:
Aging Time
Master table addresses will be discarded after reaching the set time limit. The
default setting for this parameter is 5 minutes. The maximum time for this value is
9999 minutes. A value of 0 will disable the removal of addresses based on age.
Demand Aging Level
This parameter works in the same way as port demand aging level, only using the
system address table. The default value is 90%.
