wfOspfLsdbChecksum
Module: Wellfleet-OSPF-MIB
OID (symbolic): Wellfleet-OSPF-MIB::wfOspfLsdbChecksum
OID (numeric): 1.3.6.1.4.1.18.3.5.3.2.3.3.1.7
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: 'This field is the checksum of the complete contents of the advertisement, excepting the age field. The age field is excepted so that an advertisement's age can be incremented without updating the checksum. The checksum used is the same that is used for ISO connectionless datagrams; it is commonly referred to as the Fletcher checksum.' REFERENCE 'OSPF Version 2, Section 12.1.7 LS checksum'
What is wfOspfLsdbChecksum?
The Fletcher checksum computed over the LSA's contents, excluding the age field (so the checksum stays valid as the age increments). This is primarily an internal integrity value; admins would rarely inspect it directly except when diagnosing suspected LSA corruption during flooding.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.2.3.3.1.7 snmpwalk -v2c -c public <target> Wellfleet-OSPF-MIB::wfOspfLsdbChecksum
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.18.3.5.3.2.3.3.1.7.1 snmpget -v2c -c public <target> Wellfleet-OSPF-MIB::wfOspfLsdbChecksum.1
