This read-only counter reports the 5-minute peak value of inbound ODE-marked (Out-of-profile/oversubscribed Discard Eligible, a stricter discard category beyond standard DE) octets for the circuit, from Bulk Statistics. ODE traffic typically represents cells or frames that exceeded even the burst-tolerant excess rate and are the very first candidates for discard under any congestion, so a nonzero peak here signals the circuit is being driven well beyond its provisioned envelope. An engineer seeing cktInODEOctetsPeak rise steadily on a circuit that was previously clean would treat it as an earlier warning sign of oversubscription than the standard DE counters alone would provide.
