The current CEF operational state of the CEF peer entity.
Cef peer entity oper state will be peerDisabled(1) in
the following condition:
: Cef Peer entity encounters fatal error i.e. resource
allocation failure, ipc failure etc
: When a reload/delete request is received from the Cef
Peer Entity
Once the peer entity is up and no fatal error is encountered,
then the value of this object will transits to the peerUp(3)
state.
If the Cef Peer entity is in held stage, then the value
of this object will be peerHold(3). Cef peer entity can only
transit to peerDisabled(1) state from the peerHold(3) state.
