Static Addresses. Static addresses are entries that you manually add to the address table.
These addresses remain in the address table until you intentionally delete them. The effect of
these addresses varies depending on the operating state of the bridge:
In learning mode (either Learning or Learning/STP operating states), you add static
entries to the table to prevent communication to specific nodes. In learning mode, if a
packet is received with a destination address that matches a static entry in the address
table, the packet is discarded. In learning mode, there is a limit of 256 static entries.
In secure mode (either Secure or Secure/STP operating states), you add static entries to
the table only for those nodes allowed to communicate across the bridge. In secure
mode, a packet will only be forwarded if it has both source and destination addresses
that match address table static entries. In this mode, the limit of static entries is the total
table size (512) minus the number of permanent entires.
