frameLog
Displays information about discarded frames.
SYNOPSIS framelog --disable [-type timeout | du | unroute]
framelog --enable [-type timeout | du | unroute]
framelog --clear
framelog --status
framelog --show [-type timeout | du | unroute]
[-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. Beginning with Fabric OS v7.3.0, 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.
SFID
Source Fabric ID
