The value of the object tmnxDhcpSvrSubnetBindState indicates the binding state of this subnet. 'notBound' There is no active binding. 'offered' The binding has been made, triggered by a DHCP DISCOVER message. It exists for the lifetime of the offered lease in the server, or can be made stable in case a REQUEST comes in and the binding becomes 'bound'. 'bound' There is a stable lease for this binding. 'unbinding' All clients abandoned the subnet and the binding is preserved for the interval of tmnxDhcpServerPoolSubnetBindDly; if during that period - a REQUEST comes in and a stable lease is created, then the binding becomes bound again; - a DISCOVER comes in, the state the state will not change; the timer started with tmnxDhcpServerPoolSubnetBindDly will keep running; when it expires, the binding will be removed and returns to the unbound state.
