A read-only enumerated value reporting the actual operational state of the frame relay link, which is enabled only if the physical port is up, the admin state is enabled, and, if LMI is used, the LMI protocol layer is up. Because this combines three separate conditions, an admin uses it as a single quick check of overall link health rather than having to inspect the physical port status, admin state, and LMI status individually. If cmFrDlcmiOperState reports disabled despite cmFrDlcmiAdminState being enabled, the admin would check the physical port status or LMI protocol layer as the likely remaining cause.
