Status Monitoring and Statistics
Slot Diagnostics
The BlackDiamond switch provides a facility for running normal or extended diagnostics on an
Input/Output (I/O) module or a Management Switch Fabric Module (MSM) without affecting the
operation of the rest of the system.
If you run the diagnostic routine on an I/O module, that module is taken offline while the diagnostic
test is performed. Traffic to and from the ports on that I/O module is temporarily unavailable. Once the
diagnostic test is completed, the I/O module is reset and becomes operational again.
If you run diagnostics on an MSM, that module is taken offline while the diagnostics test is performed.
When the diagnostic test is complete, the MSM reboots and becomes operational again.
To run diagnostics on I/O or MSM modules, use the following command:
run diagnostics [extended | normal] slot [<slot> | A | B]
where the following is true:
• normal—Takes the switch fabric and ports offline, and performs a simple ASIC and packet loopback
test on all ports.
• extended—Takes the switch fabric and ports offline, and performs extensive ASIC, ASIC-memory,
and packet loopback tests. Extended diagnostic tests take a maximum of 15 minutes. The CPU is not
tested. Console access is available during extended diagnostics.
• <slot>—Specifies the slot number of an I/O module. When the diagnostics test is complete, the
system attempts to bring the I/O module back online.
• A | B—Specifies the slot letter of the master MSM. The diagnostic routine is performed when the
system reboots. Both switch fabric and management ports are taken offline during diagnostics.
To display the status of the last diagnostic test run on the switch, use the following command:
show diagnostics slot [<slot> | A | B]
Port Statistics
ExtremeWare XOS provides a facility for viewing port statistical information. The summary information
lists values for the current counter for each port on each operational module in the system; and the
display is refreshed approximately every 2 seconds. Values are displayed to nine digits of accuracy.
To view port statistics, use the following command:
show ports <port_list> statistics
The switch collects the following port statistical information:
• Link Status—The current status of the link. Options are:
— Ready (the port is ready to accept a link).
— Active (the link is present at this port).
• Transmitted Packet Count (Tx Pkt Count)—The number of packets that have been successfully
transmitted by the port.
