dot3CollFrequencies
Module: EtherLike-MIB
OID (symbolic): EtherLike-MIB::dot3CollFrequencies
OID (numeric): 1.3.6.1.2.1.10.7.5.1.3
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: A count of individual MAC frames for which the transmission (successful or otherwise) on a particular interface occurs after the frame has experienced exactly the number of collisions in the associated dot3CollCount object.
For example, a frame which is transmitted on interface 77 after experiencing exactly 4 collisions would be indicated by incrementing only dot3CollFrequencies.77.4. No other instance of dot3CollFrequencies would be incremented in this example.
This counter does not increment when the interface is operating in full-duplex mode.
Discontinuities in the value of this counter can
occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime.
What is dot3CollFrequencies?
This counter, indexed by a specific collision count from 1 to 16, records how many frames on this interface were successfully transmitted after experiencing exactly that many collisions. Admins use the full histogram across all collision-count indexes to gauge how congested a half-duplex segment is, since a shift toward higher collision counts signals a busier or more contended shared medium. For example, dot3CollFrequencies.77.4 counts frames on interface 77 that succeeded after exactly 4 collisions, and a rising value there on an old shared hub segment would indicate growing contention.
