Viewing System Statistics

The systat command displays statistics related to system, power, and environment. To view
these parameters, enter
systat
at the system prompt. A screen similar to the following will be displayed.
System Uptime 1 days, 12:09:22.64
MPM Transmit Overruns : 0
MPM Receive Overruns : 22
MPM total memory : 16 MB
MPM free memory : 6522536 bytes
MPM CPU Utilization ( 5 sec) : 5% ( 0% intr 0% kernel 3% task 95% idle)
MPM CPU Utilization ( 60 sec) : 5% ( 0% intr 0% kernel 3% task 96% idle)
Power Supply 1 State : OK
Power Supply 2 State : Not Present
Temperature Sensor : OK - Under Threshold
Temperature : 37:00c 98.60f
Temperature Alarm Masking : Disabled
The fields displayed by the systat command are described below.
System Uptime. The time since the last boot that the system has been running, displayed in
days, hours, minutes, and seconds (to the nearest hundredth).
MPM Transmit Overruns. The number of times a VSE transmit buffer could not be allocated by a
task on the MPX.
MPM Receive Overruns. The number of times packets were dropped because the bus had more
packets to deliver than the MPX could handle. This is a “receive overrun” condition which can
happen when a storm occurs or when the switch is first powered up and many unknown
MAC frames are being forwarded to the MPX.
MPM total memory. The amount of total memory installed on the MPX.
MPM Free Memory. The amount of free, or unused, memory available in the MPX. This data is
also displayed by the memstat command, which is described in Viewing MPX Memory Statis-
tics on page 9-20.
MPM CPU Utilization (5 seconds). The amount of time, by percent, the MPX processor actually
worked during the last 5 seconds.
MPM CPU Utilization (60 sec). The amount of time, by percent, that the MPX processor actually
did work during the last minute.
Power Supply 1 State. Valid states are OK, Not Present, and Bad. A power supply that has been
turned off will be in the Bad state. If not installed, it will be in the Not Present state.
Power Supply 2 State. Valid states are OK, Not Present, and Bad. A power supply that has been
turned off will be in the Bad state. If not installed, it will be in the Not Present state.
Temperature Sensor. Indicates whether the MPX temperature sensor detects overheating. Valid
states are Under Threshold, Over Threshold, and Not Present.
Temperature. Indicates the switch temperature Celsius and Fahrenheit.
Temperature Alarm Masking. Indicates whether temperature alarm masking is Enabled or
Disabled. You enable masking through the maskta command, which is described in Chapter
36, “Running Hardware Diagnostics.”
