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 subnetwork-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 transmitted because of errors.
CRC Errors Number of Ethernet Cyclic Redundancy Check errors detected by this device.
Ethernet-Like
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 transmission 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
Octets Number of octets passing through this port.
Multiple Collisions A count of successfully transmitted frames for which transmission is inhibited by more
than one collision.
Late Collisions The number of times that a collision is detected later than 512 bit-times into the
transmission of a packet.
Carrier Sense
Errors
The number of times that the carrier sense condition was lost or never asserted when
attempting to transmit a frame.
Fragments The total number of frames received that were less than 64 octets in length (excluding
framing bits, but including FCS octets) and had either an FCS or alignment error.
Jabbers The total number of frames received that were longer than 1518 octets (excluding
framing bits, but including FCS octets), and had either an FCS or alignment error.
NOTES: Statistics are refreshed every 10 seconds by default (See “4.4.2 Configuring the Serial Port”).
