What is tcpEStatsListenerHCInitial?

64-bit version of tcpEStatsListenerInitial for very high-connection-rate systems, avoiding the wraparound the 32-bit counter would suffer at extreme rates.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.156.1.1.1.1.8
snmpwalk -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsListenerHCInitial

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.156.1.1.1.1.8.1
snmpget -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsListenerHCInitial.1

Start monitoring vendor-neutral, standards-based MIB, hosts/servers/network devices running a TCP/IP stack (extended TCP performance diagnostics) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the TCP-ESTATS-MIB::tcpEStatsListenerHCInitial OID value, configure state conditions and alerts, and monitor any vendor-neutral, standards-based MIB, hosts/servers/network devices running a TCP/IP stack (extended TCP performance diagnostics) from a single console.
