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.
