station cache so long as it remains active in the system - a condition that is determined by
the “aging interval.” For details see the
4.4.2.1 Bridge: Global Settings
screen, and the
4.4.2.3 Bridge: Station Cache
screen.
Learned
– This is a static address that is learned by the bridge when address-based
ethernet port security is enabled for a port. Once a static address has been learned for a
secure port, the port will be disabled if frames sourced from any other MAC address are
received. See the
4.8.2 Ethernet Port
screen.
4.4.2.1 Bridge: Global Settings
This screen displays the aging interval applied to MAC addresses learned by the bridge and
enables you to edit that setting.
FIGURE 4–34: Ethernet: Bridge: Global Settings
Table 4–34:: Ethernet: Bridge: Global Settings
describes the parameter you can configure in
the Ethernet: Bridge: Global Settings screen.
4.4.2.2 Bridge: Static MACs
The bridge station cache is a database that stores information about MAC addresses and
their associated ports. This screen enables you to add the MAC addresses of stations to
this cache or to remove them from the cache.
By factory default the static MAC address table is empty.

Field Value
Aging Interval:
Entries (MAC addresses) learned by the bridge are deleted from
the cache after they have been in the cache for the specified
aging time without another packet arriving with the same
source address.
Default value = 300 seconds (5 minutes)
Valid range = 15 seconds - 1,800 seconds (30 minutes)
