Embedded Port log (Advanced log)
This log provides a detailed history log of all traffic passing through the embedded port. The
Embedded Port (EP) of the Switch is a single physical FC port within the hardware architecture that
is used to communicate FC frames between devices attached to the external ports and the
embedded firmware’s FC services software, based on the use of well-known Fibre Channel
addresses. This is similar to the function of the Control Unit Port (CUP) in FICON architecture. The
CUP is implemented via the EP for FICON traffic. The Embedded Port Log will log all FC frame
traffic directed to the switch (EP), including discards, frames not routed, and traffic designated for
the EP (inband traffic), as shown in Figure 59 .

• Non-wrapping Log or Wrapping Log—From the submenu, select Non-wrapping log or
Wrapping log, Wrapping log is the default.
• Log Settings— Displays the current settings of the log options configured on the Switch. These
settings affect how log data is captured and stored on the Switch, not just what is displayed in
the dialog box. For example, if the Include Class F Frames is turned off or unchecked, Class F
frames are not captured or stored in the log on the Switch and are not accessible from this log.
To change these options, click the Change... button. For information, Change button-130
• Date and Time—The date and time that the event occurred. The format is yyyy/mm/dd
hh:mm:ss:tt. The last two characters (hundredth of seconds) are needed due to possible higher
frequency rate of some of the advanced logs.
• Port—The decimal receive port number on the local Switch associated with the flow that was
rerouted. When FICON style is on, the hexadecimal equivalent of the port number appears in
parentheses. When FICON style is off, only the decimal value is shown and there is no value in
the parenthesis.
• Direction—In or Out indicates the direction of the frame in reference to the embedded port
and is related to the port number. For example, if In appears, then the frame is coming into the
embedded port from the port number specified in the Port box.
