Node type: OBJECT-TYPE
Type: INTEGER

Description: The algorithm used to determine the timeout value (T3-rtx) used for re-transmitting unacknowledged chunks.
What is ceSctpRtoAlgorithm?
This object names which algorithm, either a vendor-specific other scheme or the standard Van Jacobson-derived vanj algorithm, this device's SCTP stack uses to compute the T3-rtx retransmission timeout for unacknowledged chunks. This affects how aggressively the device backs off after packet loss on a signaling link, so knowing which algorithm is active helps explain observed retransmission timing when troubleshooting delayed SS7-over-IP call setup. A value of vanj(2) tells the admin the RTO is being smoothed with the same style of algorithm TCP uses, rather than a vendor-tuned scheme.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.9.10.74.1.1.1 snmpwalk -v2c -c public <target> CISCO-SCTP-MIB::ceSctpRtoAlgorithm
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.9.10.74.1.1.1.1 snmpget -v2c -c public <target> CISCO-SCTP-MIB::ceSctpRtoAlgorithm.1
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> ceSctpRtoAlgorithm.1
