MIB Statistics
MIB Object Definitions for Counters
The following MIB objects are those for which counters are displayed in the Statistics Counters screens shown in both the console and Web interface. The definitions and references are quoted from RFC 1516.
Readable Frames
"This object is the number of frames of valid frame length that have been received on this port. This counter is incremented by one for each frame received on this port whose OctetCount is greater than or equal to minFrameSize and less than or equal to maxFrameSize (Ref: IEEE 802.3 Std, 4.4.2.1) and for which the FCSError and CollisionEvent signals are not asserted.
This statistic provides one of the parameters necessary for obtaining the packet error rate. The approximate minimum time for rollover of this counter is 80 hours."
Reference: IEEE 802.3 Rptr Mgt, 19.2.6.2, aReadableFrames
Readable Octets
"This object is the number of octets contained in valid frames that have been received on this port. This counter is incremented by OctetCount for each frame received on this port which has been determined to be a readable frame (i.e., including FCS octets but excluding framing bits and dribble bits).
This statistic provides an indicator of the total data transferred. The approximate minimum time for rollover of this counter is 58 minutes."
Reference: IEEE 802.3 Rptr Mgt, 19.2.6.2, aReadableOctets
FCS Errors
"This counter is incremented by one for each frame received on this port with the FCSError signal asserted and the FramingError and CollisionEvent signals deasserted and whose OctetCount is greater than or equal to
