Managing the Port Address Table
The Port Address Table is a table of node addresses that the device
receives on its ports. It uses the information in the table to decide
whether a frame should be forwarded or filtered.
By modifying entries in the Port Address Table, you can restrict access to
certain ports by specifying the physical addresses that are allowed to
connect to the ports.
The table holds a maximum of 500 entries. Initially, all entries are age-
ing entries (that is, they are removed from the table if, after a period of
time, the device has not transmitted or if the device is reset or powered
off). Entries can be set as “permanent” to remain in the table regardless
of the aging time or if the switch is powered off or reset.
