Why the FR Link Protocol Cannot Go Up?

Why the FR Link Protocol Cannot Go Up?

The possible cause is that the interface configurations on the two ends are incorrect, including:

  • The interface types must be DTE on one end and DCE on the other end.
  • The DLCI is not configured on the interface or the DLCI range setting is incorrect. The DLCI ranges from 16 to 1022.
  • The FR Local Management Interface (LMI) protocol types are different.
  • The FR encapsulation formats configured on the two ends are different. When the FR protocol is used as the encapsulation protocol, the default frame encapsulation format is IETF.
  • If the E1/T1 board is used, the interface TSs on the two ends do not completely match.
