Port Statistics; Etherlike Statistics - Alcatel OmniStack 8008 User Manual

Port Statistics

Use the Port Statistics menu to display Etherlike or RMON statistics for any port on
the switch. Select the required port. The statistics displayed are indicated in the
following figure and table.

Etherlike Statistics

Etherlike Statistics display key statistics from the Ethernet-like MIB for each port.
Error statistics on the traffic passing through each port are displayed. This
information can be used to identify potential problems with the switch (such as a
faulty port or unusually heavy loading). Values displayed have been accumulated
since the last system reboot.

Description
The number of frames received that are not an integral number of octets in
length and do not pass the FCS check.
The number of frames received that are an integral number of octets in length
but do not pass the FCS check.
The number of successfully transmitted frames for which transmission is
inhibited by exactly one collision.
more that one collision.
A count of times that the SQE TEST ERROR message is generated by the PLS
sublayer.
A count of frames for which the first transmission attempt on a particular
interface is delayed because the medium was busy.
The number of times that a collision is detected later than 512 bit-times into the
transmission of a packet.
The number of frames for which transmission failed due to excessive collisions.
The number of frames for which transmission failed due to an internal MAC
sublayer transmit error.
The number of times that the carrier sense condition was lost or never asserted
when attempting to transmit a frame.
The number of frames received that exceed the maximum permitted frame size.
The number of frames for which reception failed due to an internal MAC
sublayer receive error.
