Description: The number of QSaal transmit discards on this port.

What is svcAtmConfigQSaalNumDiscardTx?

This counter tracks the number of SSCOP (QSaal) transmit discards on this port, i.e. outbound PDUs at the SSCOP layer that were dropped rather than sent, per the description. Since discards at this layer happen below the Q.93b signaling messages themselves, a rising count here even while Q.93b-level counters look normal points to a resource problem (such as buffer exhaustion) in the SSCOP transmit path on this specific port rather than a signaling-logic issue. This is a counter worth correlating with overall port congestion or CPU load on the card hosting this interface.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.5.2.2.1.57
snmpwalk -v2c -c public <target> CASCADE-MIB::svcAtmConfigQSaalNumDiscardTx

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.277.5.2.2.1.57.1
snmpget -v2c -c public <target> CASCADE-MIB::svcAtmConfigQSaalNumDiscardTx.1
