Flow
Control
Mode
Determines if IEEE 802.3z pause control is used on this
port. The pause mechanism allows the port to stop a
sending station from sending more packets if the
receiving port’s buffers are full. This helps prevent lost
or dropped packets.
This feature is recommended for use primarily on end
station connections. Using this feature on trunk ports
can cause unnecessary congestion on the network.
Remote
Fault
Detect
Proprietary mechanism to detect remote link errors on
Cajun gigabit ports. The default value is Disabled.
The remote fault detection functionality should be
enabled (on both ends of a Cajun to Cajun link) in two
cases:
• When two Cajun gigabit ports are connected that
do not support auto-negotiation.
• When a Cajun gigabit port that does not support
auto-negotiation is connected to a Cajun gigabit
port that does support auto-negotiation.
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.
