Description: The maximum number of PDU's transmitted before a POLL PDU is transmitted.
What is svcAtmConfigQSaalMaxPD?
This value sets the maximum number of PDUs the SSCOP (QSaal) layer on this port will transmit before it must send a POLL PDU to solicit a status report from the far end, per the description. It's effectively the throughput-versus-overhead knob for SSCOP's selective-repeat error recovery: a smaller MaxPD polls more often and detects lost sequenced-data PDUs sooner at the cost of more POLL/STAT traffic (visible in NumPollPduTx and NumStatPduRx), while a larger MaxPD reduces overhead but delays loss detection. On a high-volume signaling link a MaxPD of around 25 is a common tradeoff point.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.277.5.2.2.1.50 snmpwalk -v2c -c public <target> CASCADE-MIB::svcAtmConfigQSaalMaxPD
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.277.5.2.2.1.50.1 snmpget -v2c -c public <target> CASCADE-MIB::svcAtmConfigQSaalMaxPD.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.277.5.2.2.1.50.1 i <value>
