tcpRtoAlgorithm
Module: TCP-MIB
OID (symbolic): TCP-MIB::tcpRtoAlgorithm
OID (numeric): 1.3.6.1.2.1.6.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: The algorithm used to determine the timeout value used for retransmitting unacknowledged octets.
What is tcpRtoAlgorithm?
This read-only object specifies which algorithm the TCP implementation uses to compute retransmission timeout (RTO) intervals for unacknowledged data segments. Common algorithms include Van Jacobson's adaptive algorithm (used by most modern systems) or constant timeout values. Network operators examine this to understand how the system adapts packet retransmission timing to network conditions.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.6.1 snmpwalk -v2c -c public <target> TCP-MIB::tcpRtoAlgorithm
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.6.1.1 snmpget -v2c -c public <target> TCP-MIB::tcpRtoAlgorithm.1
Start monitoring vendor-neutral, standards-based MIB, any host/server/network device running a TCP/IP stack (TCP connection/segment counters) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the TCP-MIB::tcpRtoAlgorithm OID value, configure state conditions and alerts, and monitor any vendor-neutral, standards-based MIB, any host/server/network device running a TCP/IP stack (TCP connection/segment counters) from a single console.
