cwtDBLastChange
Module: CISCO-WAN-TOPOLOGY-MIB
OID (symbolic): CISCO-WAN-TOPOLOGY-MIB::cwtDBLastChange
OID (numeric): 1.3.6.1.4.1.9.9.234.1.1.3
Node type: OBJECT-TYPE
Type: TimeStamp
Access: read-only
Description: The value of MIB II's sysUpTime object at the time that: a) the topology database is last changed on this node. b) the cwtGatewayAdminStatus is last changed. c) the cwtGatewayNodeOperStatus enters the 'enabledAndFull' state.
What is cwtDBLastChange?
This read-only TimeStamp captures the value of sysUpTime at the most recent of three events: a change to the topology database, a change to cwtGatewayAdminStatus, or the moment cwtGatewayNodeOperStatus entered the enabledAndFull state. An admin uses it to tell how fresh the topology data is and to correlate topology changes with other events logged around the same sysUpTime. For example, a cwtDBLastChange value that hasn't advanced in hours despite known network changes elsewhere would suggest this node's topology database has stopped updating.
