What is tcpEStatsStackSndInitial?
This connection's initial send sequence number (ISS), fixed for the life of the connection; mainly useful for correlating with packet captures or other tools that reference raw sequence numbers.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.156.1.1.5.1.37 snmpwalk -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsStackSndInitial
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.156.1.1.5.1.37.1 snmpget -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsStackSndInitial.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> tcpEStatsStackSndInitial.1
