Description Use the fr lmi n391dte command to configure the full status polling interval at the DTE side. Use the undo fr lmi n391dte command to restore the default. -
Page 82: Fr Lmi N392Dte
Description Use the fr lmi n392dce command to set N392 parameter at the DCE side. Use the undo fr lmi n392dce command to restore the default. By default, the parameter value is 3. The DCE requires the DTE to send a Status-Enquiry message at a regular interval (set by T392). If the DCE does not receive the Status-Enquiry message within a period of time, the error counter on DCE increments by one. -
Page 83: Fr Lmi N393Dce
If the errors exceed the threshold, the DTE will consider that the physical channels and all the DLCIs to be unavailable. N392 and N393 together define the “error threshold”. N393 indicates the number of events observed and N392 indicates the error threshold for that number (N393). If N392 errors occurred in N393 Status-Enquiry messages in the DTE, the DTE would consider that the error had exceeded the threshold and declare the physical channels and all DLCIs to be unavailable. -

Description Use the link-protocol fr command to encapsulate interface link layer protocol as frame relay. By default, the link-layer protocol encapsulated on the interface is PPP, and the frame relay encapsulation format is IETF. The frame relay encapsulation can be either ietf or nonstandard. IETF encapsulation conforms to RFC 1490, and it supports the IETF standard and is compatible with dedicated encapsulation format of mainstream routers. -
