swL3OspfInternalLsdbChecksum
Module: DGS-3620-28SC-L3MGMT-MIB
OID (symbolic): DGS-3620-28SC-L3MGMT-MIB::swL3OspfInternalLsdbChecksum
OID (numeric): 1.3.6.1.4.1.171.11.118.2.3.13.1.1.8
Node type: OBJECT-TYPE
Type: Integer32
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 connec- tionless datagrams; it is commonly referred to as the Fletcher checksum.
What is swL3OspfInternalLsdbChecksum?
Fletcher checksum over the LSA's contents excluding the age field, so the checksum stays valid as age increments. An admin checks this against a second capture of the same LSA to detect corruption or an unexpected content change beyond the normal age increase.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.171.11.118.2.3.13.1.1.8 snmpwalk -v2c -c public <target> DGS-3620-28SC-L3MGMT-MIB::swL3OspfInternalLsdbChecksum
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.171.11.118.2.3.13.1.1.8.1 snmpget -v2c -c public <target> DGS-3620-28SC-L3MGMT-MIB::swL3OspfInternalLsdbChecksum.1
