Module: TCP-ESTATS-MIB
OID (symbolic): TCP-ESTATS-MIB::tcpEStatsStackDSACKDups
OID (numeric): 1.3.6.1.2.1.156.1.1.5.1.34
Node type: OBJECT-TYPE

Access: read-only
Description: The number of duplicate segments reported to the local host by D-SACK blocks.
What is tcpEStatsStackDSACKDups?
Count of duplicate segments reported to this host via D-SACK blocks; a rising count indicates unnecessary retransmissions are happening because the peer is telling this host it already had the data, often a symptom of an overly aggressive RTO or reordering.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.156.1.1.5.1.34 snmpwalk -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsStackDSACKDups
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.156.1.1.5.1.34.1 snmpget -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsStackDSACKDups.1
