Brocade Adapters Troubleshooting Guide 8153-1002145-01Statistics 3Displaying logical port statistics through BCUUse the lport --stats command to display logical port statistics.lport –-stats [-l ]where:port_id ID of the port for which you want to display statistics. This could be thePWWN, port hardware path, or user-specified port name. This could also bethe adapter-index/port-index. For example, to specify adapter 1, port 1, youwould use 1/1 as the port identification.-l lpwwn Logical port world wide name for which you want to display statistics. This isan optional argument. If the -l lpwwn argument is not specified, the base portis used.Performance dataUsing HCM, you can collect real-time and historical performance data on the following manageddevices:• Port statistics for the adapter.• Virtual Port statistics on the virtual port• Ethernet statistics on the Ethernet node• FCP IM statistics on the remote portData is displayed in graphs using utilization (Mbps) and errors per second. Polling intervals can beconfigured to 10, 20, and 30 seconds. Data collected will not be lost once the graph is closed.To generate a real-time performance graph for a device, complete the following steps.1. Select the device (such as adapter, remote port, virtual port) Ethernet node) for which you wantto generate a real-time performance graph.2. Select Configure > Performance > Realtime Statistics.PHY module statisticsThe Ethernet PHY module, located in the mezzanine card port hardware, aids in communications toand from the Ethernet LAN. Use the bcu phy --stats command to display the following statistics:• PHY status• Line breaks after linkup• PMA (physical medium attachment sublayer) and PMD (physical medium dependent sublayer)receive and transmit faults• PCS (physical coding sublayer) receive and transmit faults• Speed negotiations• Transmit EQ trainings and timeouts• CRC errorsbcu phy --stats
