7. From the Flow Control Mode pull-down menu, select Enable
if you want the port to use Flow Control to prevent buffer
overflows.
* Note: Disable this feature only when flow control is
causing congestion in other areas of the
network.
8. From the Auto Negotiation Mode pull-down menu, select
Enable.
* Note: This feature is only available for 10/100 TX
ports. It works best when the port or device on
the other end of the connection auto-negotiates
as well. If you are having problems auto-
negotiating connections, set the modes
manually from the command line interface. For
example: set port auto 7/3 enable.
9. From the Auto Negotiation Speed Advertisement and Auto
Negotiation Duplex Advertisement pull-down menus, set
Speed and Duplex Advertisement, respectively. The
switch sends these values to the device on the other end of
the connection at the start of the auto-negotiating process. In
general, the defaults are best, but there may be situations
when you want to fix one setting, but allow the other setting
to auto-negotiate.
* Note: This feature is only available for 10/100 TX
ports.
10. From the Rate Limit Mode pull-down menu, select Enable
if you want this port to limit the number of unknown unicast
and multicast (flooded) packets it tries to forward.
11. From the Rate Limit Rate pull-down menu, select the
percentage of a port's traffic that can be unknown unicast
and broadcast packets. Lower this value if the port is having
overflow problems.
12. From the Rate Limit Burst Size pull-down menu, select a
packet limit for the number of packets allowed in a single
burst. Valid values are 1 to 2048. For Fast Ethernet ports, set
this value lower than 1024 (the output buffer's capacity). Set
this value lower if the port is experiencing overflow
problems.
