Basic Configuration

4.3.3.1 Switch
IEEE 802.3x flow control works by pausing a port when the port becomes oversub-
scribed and dropping all traffic for small bursts of time during the congestion condi-
tion. This can lead to high-priority and/or network control traffic loss. When 802.3x
flow control is enabled, lower speed switches can communicate with higher speed
switches by requesting that the higher speed switch refrains from sending packets.
Transmissions are temporarily halted to prevent buffer overflows.

Description
The 802.3x flow control mode on the switch. IEEE 802.3x flow control
works by pausing a port when the port becomes oversubscribed. This
allows lower-speed switches to communicate with higher-speed
switches. A lower-speed or congested switch can send a PAUSE
frame requesting that the peer device refrain from sending packets.
Transmissions are temporarily halted to prevent buffer overflows. The
options are as follows:

Disabled: The switch does not send PAUSE frames if the port
buffers become full.

Enabled: The switch can send PAUSE frames to a peer device if
the port buffers become full.
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 num-
ber of seconds a dynamic address should remain in the MAC address
table after it has been learned.
