The Hub Port Counters Screen displays activity recorded on each hub port for
six MIB variables. The variables are retrieved from the hub's firmware. The
values shown for the variables for each port are cumulative since the hub was
powered on. The Hub Port Counters Screen enables you to determine the
traffic patterns for each port. The default variables shown are:
Valid Packets. Provides the total number of good packets (packets with no
errors) seen by the port.
Collisions. Provides the total number of collisions on the port. A collision is
generated when two or more devices attempt to transmit a message on a cable
at the same time; they are capable of degrading each other's transmission. The
number of collisions should be proportional to the number of packets trans-
mitted over time and the number of nodes on the network. Collisions are a
normal occurrence on a CSMA/CD network collision domain.
CRC/Alignment Errors. Provides the total number of errors associated with
a Cyclic Redundancy Check code which is typically placed at the end of the
frame or packet to ensure the integrity of the data within the frame.
