The text description for the log entry.
Configuring and Searching the Forwarding Database
The
maintains a list of MAC addresses after having received a packet from this MAC address. The
transparent bridging function uses the forwarding database entries to determine how to forward a
received frame.
Switch Configuration
Use the Switch Configuration page to set the amount of time to keep a learned MAC address entry in
the forwarding database. 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.

Table 107: Switch Configuration Fields
Field
Description
802.3x Flow Control Mode
Enable or disable 802.3x flow control on the switch. IEEE 802.3x flow control
works by pausing a port when the port becomes oversubscribed. It also allows a
port to drop all traffic for small bursts of time during the congestion condition.
This can lead to high-priority and/or network control traffic loss. When enabled,
flow control allows lower speed switches to communicate with higher-speed
switches by requesting that the higher-speed switch refrain from sending
packets. Transmissions are temporarily halted to prevent buffer overflows.
MAC Address Aging Interval
The MAC address table (forwarding database) contains static entries, which
never age out, and dynamically-learned entries, which are removed if they are
not updated within a given time. Specify the number of seconds a dynamic
address should remain in the MAC address table after it has been learned.
Note
IEEE 802.1D recommends a default of 300 seconds, which is the factory default.

to apply the changes to the system. If you want the
switch to retain the new values across a power cycle, you must save the configuration.
