Statistics
3
port_id Specifies the ID of the Ethernet port for which you will display the statistics.
--statsclr Clears the Ethernet IOC-level statistics.
port_id Specifies the ID of the Ethernet port for which you will reset the statistics.
FCoE statistics (CNA only)
Use HCM to display statistical information related to a selected Fibre Channel over Ethernet (FCoE)
port. Statistics include the number of transmitted and received packets and transmitted and
received bytes. You can also select options to continue running data, configure polling frequency,
and start polling.
To display FCoE statistics through HCM, use the following steps.
1. Select an FCoE port from the device tree.
2. Select Monitor > Statistics > FCoE Statistics from the device tree.
OR
Right-click the FCoE port and select Statistics > FCoE Statistics from the list.
3. The FCoE Statistics dialog box at the host level displays.
Fabric statistics
Use BCU and HCM to display statistics for fabric login (FLOGI) activity and fabric offlines and
onlines detected by the port. Use these statistics to help isolate fabric login problems. Following are
two examples of how to use these statistics for troubleshooting:
• If the adapter is not showing in the fabric, check the FLOGI sent and FLOGI accept statistics. If
the counts do not match, the switch or fabric may not be ready to respond. This is normal as
long as it does not persist. If the problem persists, this could indicate a problem in the fabric or
a protocol issue between the adapter and fabric.
• If fabric offline counts increase and fabric maintenance is not being done, this may indicate a
serious fabric problem. Slow fabric performance or hosts unable to address storage could also
be seen.
Displaying fabric statistics through BCU
Use the fabric --stats command to display fabric statistics.
fabric -–stats <port_id>
where:
port_id ID of the adapter port for which you want to display statistics.
Displaying fabric statistics through HCM
Use the Fabric Statistics dialog box to monitor a variety of port data.
1. Launch the HCM.
2. Select the base adapter port from the device tree window.
3. Click Monitor > Statistics > Fabric Statistics.
