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.”
