acdPortTxStatsExcessiveCollisions
Module: ACD-PORT-MIB
OID (symbolic): ACD-PORT-MIB::acdPortTxStatsExcessiveCollisions
OID (numeric): 1.3.6.1.4.1.22420.2.9.1.3.1.1.15
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: This is a count of the number of packets dropped by this port due to excess collisions (number of collisions equals MaxRetry+1). This count does not include packets dropped due to FIFO underflow or late collisions (even if the late collision is also an excessive collision).
What is acdPortTxStatsExcessiveCollisions?
This counter counts the number of packets that were dropped because the port ran out of retries after too many collisions (exceeding the maximum retry limit). Network engineers check this to detect whether a port is losing traffic due to network congestion or electrical issues on the line. A value of 5 or higher suggests the port frequently gives up on transmitting packets and may need to be moved to a less congested network or configured with a different retry policy.
