adnsonetTCDownBufferOverflow
Module: ADN-MIB
OID (symbolic): ADN-MIB::adnsonetTCDownBufferOverflow
OID (numeric): 1.3.6.1.4.1.637.3.1.4.10.39.3.1.1.1.6
Node type: OBJECT-TYPE
Type: Counter
Access: read-only
Description: Number of downward (to remote equipment) cell buffer overflow events. Counter #26 of the ATM core.
What is adnsonetTCDownBufferOverflow?
This counter tracks how many times the ATM cell buffer overflowed when sending data downward to remote equipment. A network engineer monitors this metric to detect congestion or hardware issues causing cells to be dropped. If this counter increases frequently (e.g., 50+ overflows per hour), it signals that the line needs higher capacity or the remote equipment cannot keep pace.
