Table 4-13. Interface Frame Relay Options (1 of 3)

LMI Protocol
Possible Settings: Initialize_From_Net1FR1,
Initialize_From_Inte rface,
Auto_On_LMI_ Fail,
Standard,
Annex-A,
Annex-D
Default Setting:
For a user data port link:
Initialize_From_Interface
For a network link:
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_Net1 FR1 – The LMI type supported on this frame relay link will be
configured to match the LMI protocol initially discovered on the primary Network fr am e
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 pr otocol 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_Inte rface – The LMI type supported on this frame relay link will be
configured to match the LMI protocol discovered from the attached Netw ork li ne 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 user data ports discover
the LMI protocol from an attached device via LMI status polls. Frame relay links on the
network interface discover LMI protocol by sendin g poll s to an attached Network line and
“listening” for correct poll response messages.
Auto_On_LMI_ Fail – The LMI type supported on this frame relay lin k will be c onf igured 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 av ai labl e f or fra me rela y li nks on
the Port and network interfaces. Frame relay links on user data ports discover the LMI
protocol from LMI status polls by attached DTE devices. Frame relay links on the network
interface discover LMI protocol by sending polls to an at tached 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.
