wfOspfSpfHoldDown
Module: RFC7777-MIB
OID (symbolic): RFC7777-MIB::wfOspfSpfHoldDown
OID (numeric): 1.3.6.1.4.1.18.3.5.3.2.3.1.9
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Hold Down Timer for the SPF. The SPF will run at most once per hold down timer value. A value of 0 means no hold down.
What is wfOspfSpfHoldDown?
This read-write timer limits how often the router is allowed to rerun the OSPF SPF (shortest-path-first) algorithm, at most once per hold-down interval, to avoid excessive CPU load when the topology is flapping. A value of 0 removes the hold-down and lets SPF run immediately on every topology change.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.2.3.1.9 snmpwalk -v2c -c public <target> RFC7777-MIB::wfOspfSpfHoldDown
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.2.3.1.9.1 snmpget -v2c -c public <target> RFC7777-MIB::wfOspfSpfHoldDown.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.18.3.5.3.2.3.1.9.1 i <value>

Create custom SNMP monitor using the RFC7777-MIB::wfOspfSpfHoldDown OID value, configure state conditions and alerts, and monitor any legacy Wellfleet/Bay Networks routers (OSPF configuration, filename coincides with unrelated later RFC) from a single console.
