A read-write enumerated value specifying whether this circuit performs LMI polling as DTE, responds to polling as DCE, or does both as NNI. This must match the role the far-end device expects, since a mismatched LMI mode, for example two devices both configured as DTE, will prevent link status from being properly exchanged. When connecting to a network that acts as the DCE, the admin would configure this local frame relay link's cmFrDlcmiLMIMode as dte to correctly initiate LMI polling.
