Module: DGS-3620-28TC-L3MGMT-MIB
OID (symbolic): DGS-3620-28TC-L3MGMT-MIB::swL3OspfInternalLsdbChecksum
OID (numeric): 1.3.6.1.4.1.171.11.118.1.3.13.1.1.8
Node type: OBJECT-TYPE
Type: Integer32

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 connec- tionless datagrams; it is commonly referred to as the Fletcher checksum.
What is swL3OspfInternalLsdbChecksum?
The Fletcher checksum of this LSA's complete contents excluding the age field (so age can increment without invalidating the checksum), used the same way as ISO connectionless-datagram checksums. Admins rarely inspect this directly except when cross-checking LSA integrity between routers reporting a mismatch.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.11.118.1.3.13.1.1.8 snmpwalk -v2c -c public <target> DGS-3620-28TC-L3MGMT-MIB::swL3OspfInternalLsdbChecksum
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.11.118.1.3.13.1.1.8.1 snmpget -v2c -c public <target> DGS-3620-28TC-L3MGMT-MIB::swL3OspfInternalLsdbChecksum.1
