Pressing [F4] will reset the MAX (maximum) values to the CURR (current)
values.
Information in this Display:
● Received frames per sec (*10) – number of frames received by the port per
second over the five-second reporting interval, multiplied by 10.
● Transmitted frames per sec (*10) – number of frames transmitted by the port per
second over the five-second reporting interval, multiplied by 10.
●
Retran frames per sec (*10) – number of frames retransmitted by the port per
second over the five-second reporting interval, multiplied by 10.
● FCS errors/sec (*10) – number of Frame Check Sequence (the same as CRC, or
Cyclic Redundancy Check) errors received on the port per second over the five-
second reporting interval, multiplied by 10. A value consistently greater than
zero indicates line problems.
● Logical rejects/sec (*10) – sum of Rejects and Frame Rejects received on the port
per second over the five-second reporting interval, multiplied by 10. A value
consistently greater than zero indicates line problems.
● Transmit error ratio – ratio of retransmitted frames per second to successfully
transmitted frames per second on the port.
● Receive error ratio – ratio of frames rejected per second to frames accepted per
second on the port.
● % Receive port util – ratio of non-flag characters to total characters being
received by the port.
●
% Transmit port util – ratio of non-flag characters to total characters being trans-
mitted by the port.
