frameLog 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. 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. 380 Brocade Fabric OS Command Reference 53-1004112-02
