value configured through the Configure Threshold Alerts dialog
box. A value of 25 means an alert occurs when throughput
reaches 25% of port capacity.
• Interval - Time interval during which throughput is measured
and an alert can generate. 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 managed product. The log describes:
• Date/Time - Date and time the re-route occurred.
• Receive Port - Target port number (decimal) receiving Fibre
Channel traffic after the re-route.
• Target Domain - Target device domain ID (decimal) receiving
Fibre Channel traffic after the re-route.

traffic before the re-route.
• New Exit Port - Port number (decimal) transmitting Fibre
Channel traffic after the re-route.
Embedded Port Log The Embedded Port Log records all Fibre Channel frames transmitted
through the product’s 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 - Date and time frame was transmitted through the
embedded port.
• Port - Fibre Channel port number (decimal) transmitting frame
through the embedded port.
• Direction - Fibre Channel frame direction (In or Out).
• Frame Header - 24-byte frame header (hexadecimal).
• Length - Size of frame payload in bytes.
• Payload - First 32 bytes of frame payload (hexadecimal).
• SOF - Start of frame character (hexadecimal).
• EOF - End of frame character (hexadecimal).
