Troubleshooting Tips

As a general rule, you should clear all counts after the system is stabilized. When
looking at the Performance View, roughly keep track of the time interval when
errors accumulate to judge the presence and severity of a problem. Also,
recognize that there is a link recovery hierarchy implemented in Fibre Channel to
handle some level of "expected anomalies." In general, only be concerned with
error counts that increment very quickly.

Button Functions

The two buttons located at the right end of the title bar on the Statistics Values
table are:
Director Product Manager User Guide
Flows rerouted to ISL—This displays whether the optional Open Trunking
feature is installed or not. A value will only display if Open Trunking is
installed, the port is connected to an ISL, and flows were being rerouted. This
will be the number of Fibre Channel traffic flows that were rerouted to this
ISL from another ISL due to congestion.
Flows rerouted from ISL—This displays whether the optional Open

Trunking is installed, the port is connected to an ISL, and flows were being
rerouted. This is the number of Fibre Channel traffic flows that were rerouted
from this ISL to another ISL due to congestion.
Clear—The Clear button clears all counters to zero. Choosing this button
displays a Clear Request Confirmation dialog box. Confirming the request
clears the statistics in the hardware at the physical port. Note that this also
clears counters for other Product Manager users. An entry identifying when
the statistics were cleared and by whom is saved in the Audit Log.
Refresh—The Refresh button updates the data in the statistics tables and
enables you to compare values at any given time. Note that you can also
refresh data when you click the port's bar graph.
