Displaying logical port statistics through BCU
Use 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 the
PWWN, port hardware path, or user-specified port name. This could also be
the adapter-index/port-index. For example, to specify adapter 1, port 1, you
would use 1/1 as the port identification.
-l lpwwn Logical port world wide name for which you want to display statistics. This is
an optional argument. If the -l lpwwn argument is not specified, the base port
is used.
Performance data
Using HCM, you can collect real-time and historical performance data on the following managed
devices:
• Port statistics for the adapter.
• Virtual Port statistics on the virtual port
• Ethernet statistics on the Ethernet node
• FCP IM statistics on the remote port
Data is displayed in graphs using utilization (Mbps) and errors per second. Polling intervals can be
configured 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 want
to generate a real-time performance graph.
2. Select Configure > Performance > Realtime Statistics.
PHY module statistics
The Ethernet PHY module, located in the mezzanine card port hardware, aids in communications to
and 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 errors
