Statistics

Displaying logical port statistics through BCU

Use the lport --stats command to display logical port statistics.

lport –-stats <port_id> [-l lpwwn]

where:

port_id ID of the port for which you want to display statistics.

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.

rpwwn Remote port world wide name for which you want to display statistics.

Port statistics

Use BCU and HCM to display a variety of port statistics, such as transmitted and received frames

and words, received loop initialization primitive (LIP) event counts, error frames received, loss of

synchronization, link failure and invalid CRS counts, and end of frame (EOF) errors. Use these

statistics to isolate link and frame errors. For example, loss of synch and loss of signal errors

indicate a physical link problem. To resolve these problems, check cables, SFPs on the adapter or

switch, and patch panel connections.

Displaying statistics through BCU

Use the port --stats BCU command to display statistics for a specified adapter port.

port --stats <port_id>

where:

port_id ID of the port for which you want to display statistics.

Displaying statistics through HCM

Use the Port 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 > Port Statistics.

Remote port statistics

Remote port statistics can help isolate end-to-end login problems. Use HCM and BCU to display

statistics for the following:

• Port login (PLOGI) activity

• Authentication and discovery (ADISC) activity

• Logout (LOGO) activity

• RCSNs received

• Process logins (PRLI) received
