Table 4-14. CSU/DSU Frame Relay Options (1 of 2)

LMI Protocol

Possible Settings: Initialize_From_Interface, Auto On_LMI_Fail, Standard, Annex-A,

Annex-D

Default Setting: Initialize_From_Interface

Specifies either the LMI protocol supported on the frame relay interface or the discovery source for the LMI protocol.

Initialize_From_Interface – The LMI type supported on this frame relay link will be configured to match the LMI protocol discovered from the attached DTE device. Once a protocol has become active, the protocol will be set to the protocol discovered (Standard, Annex-A, or Annex-D) on the frame relay link. The frame relay link discovers the LMI protocol from an attached device via LMI status polls. The protocol will not be updated after the initial discovery.

Auto_On_LMI_Fail – The LMI type supported on this frame relay link will be configured to match the LMI protocol discovered from the attached Network line or the DTE device when an LMI Link Down failure occurs. This option is available for frame relay links on the Port and network interfaces. The frame relay link discovers the LMI protocol from LMI status polls by the attached DTE device.

Standard – Supports Standard LMI and the StrataCom enhancements to the Standard

LMI.

Annex-A– Supports LMI as specified by Q.933, Annex A.

Annex-D– Supports LMI as specified by ANSI T1.617, Annex D.

LMI Parameters

Possible Settings: System, Custom

Default Setting: System

Allows you to use the system LMI options or to set specific LMI options for this interface.

System – Use system LMI options (refer to Table 4-2, CSU/DSU Frame Relay and LMI

Options).

Custom – Use the following options in this table to configure LMI parameters.

LMI Error Event (N2)

Possible Settings: 1 – 10

Default Setting: 3

Configures the LMI-defined N2 parameter, which sets the number of errors that can occur on the LMI link before an error is reported. Applies to both the user and network sides of an UNI.

Display Conditions – This option appears only when LMI Parameters is set to Custom.

1 – 10 – Specifies the maximum number of errors.
