Description Use this command to disable or re-enable the frame log, and to display detailed information about the discarded
frames logged by the frame log. The frame log stores information about frames discarded due to certain reasons.
The frame log sees information about only 40 discarded frames per second per chip on the chassis.
When frame drops occur on a switch, the frame log can help you identify to which flows the dropped frames
belong and zero in on the affected applications by finding out the end-points of the dropped frame.
Use the --show option to display detailed information about the discarded frames that match the filter criteria
provided by this command. The --show option supports two viewing modes: summary and dump mode. In
summary mode, the command aggregates similar frames (those that have the same log timestamp, TX port, RX
port, SID, DID, SFID and DFID) without displaying the raw frame contents. In dump mode, the command displays
the raw frame contents, but the frames are not aggregated in the manner of the summary mode. In either mode,
you can specify additional filters to customize the number and properties of the frames for closer examination.
When viewed in summary mode, the frame log displays the following information:
Log timestamp
The date and time when the frames described in this line of output were discarded. This
value is accurate to within one second, that is, the displayed frames were not necessarily
dropped at precisely the same time.
TX port
Egress port where the frames were bound to exit the chassis. A port displayed as -1 (or -1/-1
on slot-based systems) indicates an internal port.
RX port
Ingress port where the frames entered the chassis. A port displayed as -1 (or -1/-1 on
slot-based systems indicates an internal port.
SID
Source port ID in hexadecimal PID format.
DID
Destination port ID in hexadecimal PID format.
