cslbxProbeState
Cisco SLB Health Monitor Probe State
1.3.6.1.4.1.9.9.254.1.6.1.1.28
This object represents the state of the probe. When the probe is associated with a real server or server farm it will be active which is represented by value 'true'. When the probe is active and if the real server is administratively put into in-service, then the real server health monitoring will be started. When the probe is not associated with a real server or server farm it will be inactive which is represented by value 'false', so no health monitoring will be performed.
