This shows the Control Channel (CC) and Connectivity Verification (CV) mechanism configured locally on this end of the pseudowire, describing which VCCV method (e.g., control word based, router alert label, or TTL expiry) this PE has been set up to use. Both PE endpoints negotiate down to a commonly supported CC/CV type during PW setup, so this local configuration is the starting point for that negotiation, not necessarily what's actually in use. Comparing this against cienaCesMplsPwOperatingCcCv tells the admin whether the local preference was actually honored or whether negotiation settled on something else.
