rptrMonitorPortCollisions
Module: SNMP-REPEATER-MIB
OID (symbolic): SNMP-REPEATER-MIB::rptrMonitorPortCollisions
OID (numeric): 1.3.6.1.2.1.22.2.3.1.1.10
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description:
For a clause 9 repeater, this counter is incremented by one for any CarrierEvent signal on any port for which the CollisionEvent signal on this port is asserted. For a clause 27 repeater port the counter increments on entering the Collision Count Increment state of the partition state diagram (fig 27-8 of [IEEE 802.3 Std]).
A discontinuity may occur in the value when the value of object rptrMonitorPortLastChange changes.
The approximate minimum time for rollover of this counter is 16 hours in a 10Mb/s repeater.
What is rptrMonitorPortCollisions?
This OID counts how many times a network collision (simultaneous packet transmissions causing interference) occurred on this port. A high count indicates network congestion or too many devices fighting for access to the same segment. A network engineer would monitor this to detect if an older Ethernet hub segment is overloaded and needs to be split or replaced.
