5.2.7.2 CPU Statistics
To display the statistics of the traffic handled by CPU, use the following command.
Command Mode Description
show cpu statistics avg-pkt
[ PORTS ]
Shows the statistics of the traffic handled by CPU per
packet type.
show cpu statistics total
[ PORTS ]
Enable
Global
Bridge
Shows the traffic statistics of the average packet han-
dled by CPU.
To delete the collected statistics of the traffic handled by CPU, use the following com-
mand.
Command Mode Description
clear cpu statistics [ PORTS ]
Global
Bridge Deletes the collected statistics of the traffic handled by
CPU.
The following is the sample output of the show cpu statistics total command with the
Ethernet port 25.
SWITCH(config)# show cpu statistics total 25

SWITCH(config)#
The switch can be configured to generate a syslog message when the number of the
packets handled by CPU exceeds a specified value. This function allows system adminis-
trators to monitor the switch and network status more effectively.
To configure the switch to generate a syslog message according to the number of the
packets handled by CPU, use the following command.
Command Mode Description
cpu statistics-limit { unicast |
multicast | broadcast } PORTS
<10-100>
Global
Generates a syslog message according to the speci-
fied number of the packets handled by CPU. This is
configurable for each packet type and physical port.
unicast | multicast | broadcast: packet type
PORTS: port numbers
10-100: packet count (actual value: 1000-10000)
