frameLog

frameLog
Displays information about discarded frames.
SYNOPSIS
framelog --disable
framelog --enable
framelog --clear
framelog --show [-txport [slot/]port]
[-rxport [slot/]port]
[-sid source_PID][-did destination_PID]
[-sfid fabric_ID] [-dfid fabric_ID>]
[-mode summary | dump] [-n num_items]
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 only discard reason currently supported is timeout.
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
TX port
RX port
SID
DID
SFID
DFID
380
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.
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.
Ingress port where the frames entered the chassis. A port displayed as -1 (or -1/-1
on slot-based systems indicates an internal port.
Source port ID in hexadecimal PID format.
Destination port ID in hexadecimal PID format.
Source Fabric ID
Destination Fabric ID
