Module: ACD-PORT-MIB
OID (symbolic): ACD-PORT-MIB::acdPortTxStatsDeferred
OID (numeric): 1.3.6.1.4.1.22420.2.9.1.3.1.1.11
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: This is a count of the number of packets that were deferred on the first transmit attempt due to the medium being busy. Packets with subsequent deferrals (for instance, after a collision back off) are not counted. Whether the packet is eventually transmitted successfully or not is irrelevant to this counter. Packets dropped due to excess deferral that occur during the initial transmit attempt are not counted.
What is acdPortTxStatsDeferred?
This counter increments when a packet is delayed before the first transmission attempt because the Ethernet medium is busy. Engineers use this to understand congestion patterns—if deferral counts are high, it indicates the network is saturated and needs more bandwidth. Example: a value of 5,000 means the port had to wait for the line to clear 5,000 times before it could even start transmitting packets.
