•Port- The port number where the alert occurred.
•Type- The type of alert: transmit (Tx) or receive (Rx).
• Utilization % - The percent usage of traffic capacity. This setting
constitutes the threshold value andis configured through the
Configure Threshold Alerts dialog box. For example, a value of 25
means that threshold occurs when throughput reaches 25 percent
of the port capacity.

measured and an alert can generate. This is set through the
Configure Threshold Alerts dialog box.
Open Trunking Log
The Open Trunking Log records ISL congestion events that cause Fibre
Channel traffic to be routed through an alternate ISL. Entries reflect
the traffic re-route status at the director.
The log describes:
• Date/Time - Thedateandtimethere-routeactionoccurred.
• Receive Port - The director port number (decimal) used for
receiving Fibre Channel traffic after the re-route action.
• Ta rg e t D om ai n - The domain ID (decimal) of the target device to
which Fibre Channel traffic from the director was rerouted.
• Old Exit Port - Thedirectorportnumber(decimal)usedfor
transmitting Fibre Channel traffic before the re-route action.
• NewExitPort-Thedirectorportnumber(decimal)usedfor
transmitting Fibre Channel traffic after the re-route action.
Imbedded Port Log
The Embedded Port Log records all Fibre Channel frames transmitted
through the product embedded port, including Class F traffic, fabric
logins, state change notifications, and exception frames. The
information is useful for Fibre Channel frame debugging (usually
performed by second-level support).
The log describes:
• Date/Time - The date and time frame was transmitted through
the embedded port.
• Port - The Fibre Channel port number (decimal) transmitting
frame through the embedded port.
