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.
