Description: -- Note that the OSPF Sequence Number is a 32 bit signed -- integer. It starts with the value '80000001'h, -- or -'7FFFFFFF'h, and increments until '7FFFFFFF'h -- Thus, a typical sequence number will be very negative. 'The sequence number field is a signed 32-bit integer. It is used to detect old and duplicate link state advertisements. The space of sequence numbers is linearly ordered. The larger the sequence number the more recent the advertisement.' REFERENCE 'OSPF Version 2, Section 12.1.6 LS sequence number'
What is wfOspfLsdbSequence?
This read-only signed 32-bit value is the sequence number OSPF uses to detect old or duplicate copies of a Link State Advertisement; sequence space is linearly ordered so a larger number always means a more recent advertisement. It typically starts near '80000001'h and is rarely inspected directly except when debugging stale-LSA problems.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.2.3.3.1.5 snmpwalk -v2c -c public <target> RFC7777-MIB::wfOspfLsdbSequence
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.2.3.3.1.5.1 snmpget -v2c -c public <target> RFC7777-MIB::wfOspfLsdbSequence.1
Start monitoring legacy Wellfleet/Bay Networks routers (OSPF configuration, filename coincides with unrelated later RFC) with a free 30-day trial of IPNetwork Monitor. Create custom SNMP monitor using the RFC7777-MIB::wfOspfLsdbSequence 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.
