extremeOspfv3AsLsdbChecksum
Module: EXTREME-OSPFV3-MIB
OID (symbolic): EXTREME-OSPFV3-MIB::extremeOspfv3AsLsdbChecksum
OID (numeric): 1.3.6.1.4.1.1916.1.50.1.3.1.6
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 connectionless datagrams; it is commonly referred to as the Fletcher checksum.
What is extremeOspfv3AsLsdbChecksum?
Fletcher checksum of this AS-scope LSA's contents, excluding the age field so incrementing the age doesn't force a checksum update. Mismatched checksums for the same LSA between routers point to a link-state database sync problem.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.1916.1.50.1.3.1.6 snmpwalk -v2c -c public <target> EXTREME-OSPFV3-MIB::extremeOspfv3AsLsdbChecksum
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.1916.1.50.1.3.1.6.1 snmpget -v2c -c public <target> EXTREME-OSPFV3-MIB::extremeOspfv3AsLsdbChecksum.1
