SYNOPSIS portcmd --ping [slot/][slot/]ge port -s src_ip -d dst_ip [-x | -crossport] [-n num_requests][-q service_type] [-t ttl][-w wait_time] [-z size][-v vlan_id [-c L2 Class-of-Service]] portcmd --traceroute [slot/][slot/]ge port -s src_ip -d dst_ip [-x | -crossport] [-h max_hops][-f first_ttl][-q type_of_service][-w timeout] [-z size] [-v vlan_id [-c L2 Class-of-Service]] portcmd --tperf [slot/]veport -sink | -source [-high | -medium | -low][-time duration] [-unidirectional] [-random] [-pattern pattern] [-size pdu_size] [-interval interval] DESCRIPTION Use this command to invoke the end-to-end IP path performance (ipperf) characterization feature, to ping or trace a route to a destination IP host from an intelligent GbE port, or to determine the path characteristics between a local data source and a remote data sink. When issued with the --tperf option, this command determines the path characteristics to a remote host or tunnel destination. TPerf generates statistics every 30 seconds by default unless you specify a different value for -interval. The output displays the following information: Tunnel ID Numeric identifier for the TPerf tunnel. Traffic Priority High, Medium, or Low. bytes tx Number of bytes transmitted. bytes rx Number of bytes received. PDUs tx Number of protocol data units transmitted. PDUs rx Number of protocol data units received. bad CRC headers rx Number of bad CRC headers received. bad CRC payloads rx Number of bad CRC payloads received. out of seq PDUs rx Number of out-of-sequence PDUs received. flow control count Flow control count. last rtt Last Round trip in milliseconds (RT traffic only).
