tcpEStatsPathRetranThresh

Module: TCP-ESTATS-MIB

OID (symbolic): TCP-ESTATS-MIB::tcpEStatsPathRetranThresh

OID (numeric): 1.3.6.1.2.1.156.1.1.4.1.1

Node type: OBJECT-TYPE

Type: Gauge32

Access: read-only

Description: The number of duplicate acknowledgments required to trigger Fast Retransmit. Note that although this is constant in traditional Reno TCP implementations, it is adaptive in many newer TCPs.

What is tcpEStatsPathRetranThresh?

Number of duplicate ACKs required to trigger Fast Retransmit on this connection; traditionally a fixed value (e.g. 3) in classic Reno TCP, but adaptive in many modern stacks, so an admin checks this rather than assuming the textbook default.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.156.1.1.4.1.1
snmpwalk -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsPathRetranThresh

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.156.1.1.4.1.1.1
snmpget -v2c -c public <target> TCP-ESTATS-MIB::tcpEStatsPathRetranThresh.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::tcpEStatsPathRetranThresh 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.
