ID
         Support: All
         Default: No default                      Value: NOde ID

         Node ID of a potential neighbor node. You cannot modify this
         characteristic. This characteristic is set by means of an argument to
         the create command.

     VERIFIER
         Support: All
         Default: No verifier                     Value: Hex-string, length 0-38

         Verifier to be checked from this neighbor. You may change this
         characteristic at any time; however, the change will not take effect
         until the circuit is next initialized. You cannot display this
         characteristic.

         If the verifier is not set, then a connection to the neighboring node
         whose ID matches the ID in this entry is allowed.  If the verifier is
         set, the connection is allowed only if the verifier sent by the remote
         node matches the one in this entry.
