adnLapFlowT203Timeouts
Module: ADN-MIB
OID (symbolic): ADN-MIB::adnLapFlowT203Timeouts
OID (numeric): 1.3.6.1.4.1.637.3.1.5.4.2.3.1.9
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: The number of times a transmission was resent because the T203 timer expired.
What is adnLapFlowT203Timeouts?
This counter tracks how many times the T203 supervision timer expired, triggering a retransmit when no frames were received from the remote side for a set period. This is important because if it fires frequently, the link may be asymmetric (one direction congested or broken) or the remote side may have stopped sending data unexpectedly. A steady T203 timeout count of 5 per minute suggests you need to increase the T203 interval or investigate why the remote isn't responding reliably.
