Table 4-7. Interface Frame Relay Options (1 of 3)
LMI Protocol
Possible Settings: Initialize_From_Net1FR1, Initialize_From_Interface,
Auto_On_LMI_Fail, Standard, Annex-A, Annex-D
Default Setting:
For user data port links:
Initialize_From_Interface
For network data port links:
Auto_On_LMI_Fail
Specifies either the LMI protocol supported on the frame relay interface or the discovery
source for the LMI protocol.
Initialize_From_Net1FR1 – The LMI type supported on this frame relay link will be
configured to match the LMI protocol initially discovered on the primary Network frame
relay link (Net1FR1). LMI Protocol is set to None internally, but once a protocol has
become active or is set on the primary Network link, the protocol will be set to the same
value on this link (Standard, Annex-A or Annex-D). The protocol will
not
be updated
based on changes to Net1FR1 after being set initially.
Display Conditions
– This option value only appears for a user data port.
Initialize_From_Interface – The LMI type supported on this frame relay link will be
configured to match the LMI protocol discovered from the attached Network line or 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. Frame relay links on the user data port
discover 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 user data port and network data ports. Frame relay links on the user data port
discover the LMI protocol from LMI status polls on attached DTE devices. Frame relay
links on the network data port discover LMI protocol by sending polls to an attached
Network line and “listening” for correct poll response messages.
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
