4.2.5 Forwarding Database
4.2.5.1 Configuration
Use this panel to set the Address Ageing Timeout for the forwarding database.
Address Ageing Timeout (seconds) - The forwarding database contains static entries,
which are never aged out, and dynamically learned entries, which are removed if they are
not updated within a given time. You specify that time by entering a value for the Address
Ageing Timeout. You may enter any number of seconds between 10 and 1000000. IEEE
802.1D recommends a default of 300 seconds, which is the factory default.
4.2.5.2 Search
Use this panel to display information about entries in the forwarding database. These entries are used by
the transparent bridging function to determine how to forward a received frame.
Configurable Data
Filter - Specify the entries you want displayed.
Learned: If you choose "learned" only MAC addresses that have been learned will be
displayed.
All: If you choose "all" the whole table will be displayed.
MAC Address Search - You may also search for an individual MAC address. Enter the two
byte hexadecimal VLAN ID followed by the six byte hexadecimal MAC address in two-digit
groups separated by colons, for example 01:23:45:67:89:AB:CD:EF where 01:23 is the
VLAN ID and 45:67:89:AB:CD:EF is the MAC address. Then click on the search button. If
the address exists, that entry will be displayed as the first entry followed by the remaining
(greater) MAC addresses. An exact match is required.
