LMI Protocol
Possible Settings: Initialize_From_Net1FR1, 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 protocol will
not
be
updated after being initially discovered. The frame relay link discovers the LMI protocol
from an attached device via LMI status polls.
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
whenever 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 (see Table 4-2, System Frame Relay and LMI
Options).
Custom – Use the following options in this table to configure LMI parameters.
LMI Error Event (N2)
Possible Settings: 1, 2, 3, 4, 5, 6, 7, 8, 9, 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 a UNI.
1 – 10 – Specifies the maximum number of errors.
