3. In the Name field, enter a port name.
4. If this is an end-station port, from the Category pull-down
menu, select User Port. For trunk ports, select Service Port.
5. From the Speed Mode pull-down menu, select a speed (10
Mbps or 100 Mbps) if you want to set the port speed
manually. If you set the port to auto-negotiate, this setting is
ignored.
* Note: This feature is only available for 10/100 TX
ports.
6. From the Duplex Mode pull-down menu, select a mode
(Half-duplex or Full-duplex) if you want to set the port’s
duplex mode manually. If you set the port to auto-negotiate,
this setting is ignored.
Rate Limit
Mode Prevents the switch from overwhelming the output
buffer on lower-speed ports by placing a threshold
on the percentage of port traffic that can be flooded
packets (unknown unicasts and multicasts). You
can optionally include known multicast packets in
this percentage to further decrease the possibility of
the port’s output buffer being overwhelmed.
Rate Limit Rate Determines the percentage of a port’s forwarded
traffic that can be unknown unicast and multicast
(flooded). Lower this value if the port has overflow
problems.
Rate Limit
Burst Size Determines the limit of packets allowed in a single
burst. Accepted values are 1 to 2048. For Fast
Ethernet ports, set this value lower than 1024
(output buffer capacity). Lower this value if the
port has overflow problems.
PACE Priority
Mode PACE Priority Mode determines if the port
detects 3Com’s proprietary PACE format as
packets pass through the port. PACE enables a
packet’s priority to be set at the adapter.
Higher priority packets move through the
switch before lower packets. PACE Priority
Mode is enabled by default. To disable PACE
Priority Mode, select Disable from the PACE
Priority Mode pull-down menu.
