vrptrMonitorPortCollisions
Module: VERTICAL-SNMP-REPEATER-MIB
OID (symbolic): VERTICAL-SNMP-REPEATER-MIB::vrptrMonitorPortCollisions
OID (numeric): 1.3.6.1.4.1.2338.4.2.3.1.1.10
Node type: OBJECT-TYPE
Type: INTEGER
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 vrptrMonitorPortCollisions?
A count of collision events detected on this port (encoded as notSupported(-1)/supported(0) per this MIB's revised syntax): for a 10Mb/s port, any carrier event coinciding with an asserted collision signal; for a 100Mb/s port, entry into the partition state machine's Collision Count Increment state. At 10Mb/s it takes roughly 16 hours to wrap.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.2338.4.2.3.1.1.10 snmpwalk -v2c -c public <target> VERTICAL-SNMP-REPEATER-MIB::vrptrMonitorPortCollisions
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.2338.4.2.3.1.1.10.1 snmpget -v2c -c public <target> VERTICAL-SNMP-REPEATER-MIB::vrptrMonitorPortCollisions.1
