Setting Speedup for a
Port
Perform the following configuration to speed up the hardware in a port or out of
a port.

CAUTION:
■ The hardspeedup enable/disable commands are applicable to type-A I/O
Modules only, including 3C16860, 3C16861, LS81FS24A, 3C16858, and
3C16859.
■ The speedup enable/disable commands are applicable to non-type-A I/O
Modules only.
■ The commands above are diagnostic, so you cannot use them at discretion.
Controlling UP/Down
Log Output on a Port
An Ethernet port has two physical link statuses: UP and Down. When the state of
an Ethernet port changes, the switch will send log information to the log server,
which then responds accordingly. If the status of Ethernet ports changes
frequently, the switch will send log information to the log server frequently,
burdening the log server and consuming plenty of network resources.
To solve the problem, you can use the Up/Down log information output control
function. By using the function, you can choose to monitor certain Ethernet ports
instead of monitoring all ports, so as to reduce the quantity of log information
output to the log server.
n
After you allow a port to output the Up/Down log information, if the physical link
status of the port does not change, the switch does not send log information to
the log server but monitors the port in real time.
