5. From the Flow Control Mode pull-down menu, select Enable
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.
6. From the PACE Priority Mode pull-down menu, select
Enable to use PACE Priority Mode to detect 3Com's
proprietary PACE format.
7. From the Remote Fault Detect pull-down menu, select
Enable to detect remote link errors.
* Notes:
• The remote fault detection functionality should be
enabled (on both ends of a Cajun to Cajun link) in
two cases. The first case is when two Cajun gigabit
ports are connected that do not support
auto-negotiation. The second case is when a Cajun
gigabit port that does not support auto-negotiation is
connected to a Cajun gigabit port that supports auto-
negotiation. If two gigabit ports that support auto-
negotiation are connected, you should enable auto-
negotiation.
• Auto-negotiation and remote fault detection cannot
be enabled concurrently. Auto-negotiation must be
disabled to enable remote fault detection. When auto-
negotiation is enabled, remote fault detection is
automatically disabled.
• For GMAC1 gigabit modules, auto-negotiation is
always disabled.
8. Click APPLY to save your changes, or CANCEL to restore
