Displaying CPU utilization statistics

You can display CPU utilization statistics for STP and the IP protocols.
To display CPU utilization statistics for STP for the previous one-second, one-minute, five-minute,
and fifteen-minute intervals, enter the following command at any level of the CLI.
PowerConnect#show process cpu
Process Name
ARP
BGP
GVRP
ICMP
IP
OSPF
RIP
STP
VRRP
If the software has been running less than 15 minutes (the maximum interval for utilization
statistics), the command indicates how long the software has been running. Here is an example.

The port STP state. The state can be one of the following:
•
BLOCKING – STP has blocked Layer 2 traffic on this port to prevent a loop.
The device or VLAN can reach the root bridge using another port, whose state
is FORWARDING. When a port is in this state, the port does not transmit or
receive user frames, but the port does continue to receive STP BPDUs.
•
DISABLED – The port is not participating in STP. This can occur when the
port is disconnected or STP is disabled on the port.
•
FORWARDING – STP is allowing the port to send and receive frames.
•
LISTENING – STP is responding to a topology change and this port is listening
for a BPDU from neighboring bridges in order to determine the new topology.
No user frames are transmitted or received during this state.
•
LEARNING – The port has passed through the LISTENING state and will
change to the FORWARDING state, depending on the results of STP
reconvergence. The port does not transmit or receive user frames during this
state. However, the device can learn the MAC addresses of frames that the
port receives during this state and make corresponding entries in the MAC
table.
The number of times STP has changed the state of this port between BLOCKING
and FORWARDING.
The cost to the root bridge as advertised by the designated bridge that is
connected to this port. If the designated bridge is the root bridge itself, then the
cost is 0. The identity of the designated bridge is shown in the Design Bridge field.
The root bridge as recognized on this port. The value is the same as the root
bridge ID listed in the Root ID field.
The designated bridge to which this port is connected. The designated bridge is
the device that connects the network segment on the port to the root bridge.
