cncNcdpEnable
Cisco Network Clock Ncdp Enable
1.3.6.1.4.1.9.9.121.1.4.1.1.1
An indication of whether NCDP is presently running on an interface. When NCDP is enabled for an interface, the interface is an active member of the clock distribution topology as seen by the NCDP protocol entity. After this object is instantiated by the agent the managed system initializes the value of this object to 'true' if it determines that the physical interface is an ATM Network-to-Network Interface (see ATM Forum Private Network-Network Interface Specification Version 1.0). In all other cases the managed system initializes the value of this object to 'false'.
