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.
• Old Exit Port - Port number (decimal) transmitting Fibre Channel
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).
NOTE: Identical entries are recorded in the wrapping and non-wrapping
logs. When the non-wrapping log fills, old records are overwritten. The
wrapping log preserves all records.
