Configuring Frame Relay for an Interface

Select Frame Relay from the interface’s menu to display or change the Frame

Relay options for an individual interface (see Table 3-25, Interface PPP Options).

Frame Relay is not an option on the Network menu unless Service Type is Frame

Relay.

Main Menu→Configuration→[Networ k/Data/T3 User Ports] →Frame Relay

See Configuring PPP for an Interface on page 3-63, for additional information.

Table 3-24. 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 a user data port link: Initialize_From_Interface
For a network link: Auto_On_LMI_Fail
Specifies either the LMI protocol suppor ted on the frame relay interface or the discov ery
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 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 sending polls to an attached Network line and
“listening” for correct poll response messages.
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. 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 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.
