mleCollisions
Module: CODIMA-EXPRESS-MIB
OID (symbolic): CODIMA-EXPRESS-MIB::mleCollisions
OID (numeric): 1.3.6.1.4.1.226.3.2.1.1.3.1.4.1.7
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: Number of Collisions. Collisions are the result of two workstations trying to use shared a transmission medium (cable) simultaneously, e.g., using Ethernet CSMA/CD. The electrical signals, which carry the information the workstations are sending, bump into each other, ruining both signals. This means both workstations will have to re-transmit their information. In most systems, a built-in delay will make sure the collision does not occur again. A value of 4294967294 indicates unknown.
What is mleCollisions?
This read-only Counter32 counts Ethernet collisions attributed to this row's MAC address (MacIndex) in the mle Ethernet-error history table, arising when two stations' signals on a shared medium overlap and corrupt each other. Seeing this broken out per host lets an admin identify which specific machine is generating (or suffering from) collisions rather than only knowing the segment as a whole is congested. An admin chasing intermittent slowness would compare mleCollisions across the rows in the mle Ethernet-error history table to find the one host whose collision count stands out from its peers.
