What is tcpEStatsListenerInitial?

Count of connections for which this listener has allocated initial state and placed them in the backlog (in SYN-RCVD or ESTABLISHED, depending on implementation); an early-stage counter in the connection-acceptance pipeline, upstream of tcpEStatsListenerAccepted.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.156.1.1.1.1.3
snmpwalk -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsListenerInitial

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.156.1.1.1.1.3.1
snmpget -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsListenerInitial.1

SNMPv3 example:

snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> tcpEStatsListenerInitial.1
