Port Statistics
Port Statistics display key statistics from the Interfaces Group and Ethernet-
like MIBs for each port. Error statistics on the traffic passing through each
port are displayed. This information can be used to identify potential prob-
lems with the Switch (such as a faulty port or unusually heavy loading). The
values displayed have been accumulated since the last system reboot.
Select the required port.
Interfaces
• In Octets - The total number of octets received on the interface, includ-
ing framing characters.
• In Unicast Pkts - The number of unicast packets delivered to a higher-
layer protocol.
• In Non-Unicast Pkts - The number of non-unicast (that is, subnetwork-
broadcast or subnetwork-multicast) packets delivered to a higher-layer
protocol.
• In Discards - The number of inbound packets which were chosen to be
discarded even though no errors had been detected to prevent their being
deliverable to a higher-layer protocol. One possible reason for discarding
such a packet could be to free up buffer space.
• In Errors - The number of inbound packets that contained errors pre-
venting them from being deliverable to a higher-layer protocol.

• Alignment Errors - The number of alignment errors (mis-synchronized
data packets).
• Out Octets - The total number of octets transmitted out of the interface,
including framing characters.
• Out Unicast Pkts - The total number of packets that higher-level proto-
cols requested be transmitted to a subnetwork-unicast address, including
those that were discarded or not sent.
• Out Non-Unicast Pkts - The total number of packets that higher-level
protocols requested be transmitted to a non-unicast (that is, a subnet-
work-broadcast or subnetwork-multicast) address, including those that
were discarded or not sent.
• Out Discards - The number of outbound packets which were chosen to
be discarded even though no errors had been detected to prevent their
being transmitted. One possible reason for discarding such a packet
could be to free up buffer space.
• Out Errors - The number of outbound packets that could not be trans-
mitted because of errors.
• CRC Errors - Number of Ethernet Cyclic Redundancy Check errors
detected by this device.
Ethernet
• Single Collisions - The number of successfully transmitted frames for
which transmission is inhibited by exactly one collision.
• Deferred Transmissions - A count of frames for which the first trans-
mission attempt on a particular interface is delayed because the medium
was busy.
• Excessive Collisions - The number of frames for which transmission
failed due to excessive collisions.
• Drop Events - The total number of events in which packets were
dropped due to lack of resources.
