ethPortCollisions
Module: MODULES-MIB
OID (symbolic): MODULES-MIB::ethPortCollisions
OID (numeric): 1.3.6.1.4.1.81.12.3.1.1.19
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: This counter is incremented by one for any CarrierEvent signal on any port for which the CollisionEvent signal on this port is also asserted.
The approximate minimum time for rollover of this counter is 16 hours. Relevant for MPR and HIMIB modules. REFERENCE Reference IEEE 802.3 Rptr Mgt, 19.2.6.2, aCollisions.
What is ethPortCollisions?
Standard IEEE 802.3 repeater collision counter for this port, incremented each time a carrier event coincides with a detected collision signal; supported on MPR and HIMIB modules, it rolls over in as little as 16 hours under heavy collision activity, so admins graphing collision rates need to poll it frequently to avoid missing wraps.
