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.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.637.3.1.4.10.39.3.1.1.1.6
snmpwalk -v2c -c public <target> ADN-MIB::adnsonetTCDownBufferOverflow

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.637.3.1.4.10.39.3.1.1.1.6.1
snmpget -v2c -c public <target> ADN-MIB::adnsonetTCDownBufferOverflow.1
