Port Packet Analysis
The Packet Analysis screen displays the size of packets received or transmitted by a given switch port.
In addition, statistics on the number and rate of unicast, multicast, and broadcast packets received by
the switch are displayed.
Parameter
The interval (in seconds) that the table is updated. The default is 2
seconds.
Received packets.
For 10 Mbps ports, the counter records CRC errors (FCS or alignment
errors). For 100 Mbps ports, the counter records the sum of CRC
errors and code errors (frames received with rxerror signal).
The total number of frames received that were less than 64 octets long
(excluding framing bits, but including FCS octets) and were otherwise
well formed.
The total number of frames received that were longer than 1518 octets
(excluding framing bits, but including FCS octets) and were otherwise
well formed.
The total number of frames received that were less that 64 octets in
length (excluding framing bits, but including FCS octets) and had
either an FCS or an alignment error.
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 an alignment error.
The total number of events in which packets were dropped due to a
lack of resources.
Transmitted packets.
The number of frames for which the first transmission attempt on a
particular interface was delayed because the medium was busy
For 10 Mbps ports, the counter records CRC errors (FCS or alignment
errors). For 100 Mbps ports, the counter records the sum of CRC
errors and code errors (frames received with rxerror signal).
Late Collisions. The number of times that a collision is detected later
than 512 bit-times into the transmission of a packet.
Excessive Collisions. The number of frames for which transmission
failed due to excessive collisions.
Single Collision Frames. The number of successfully transmitted
frames for which transmission is inhibited by more than one collision.
An estimate of the total number of collisions on this network segment.
