Protocol Menu (VHSI Tree)

(when protocol is set to Frame Relay)

These parameters are only available when the protocol is set to Frame Relay.

Local management interface

Defines the Local Management Interface (LMI) protocol supported on the network. LMI is a protocol and associated procedures operating on the local interface between the machine user and the network. LMI provides management of Data Link Connection Identifiers (DLCI), which have their endpoints and bearer capabilities defined at subscription time. Pre-ANSI LMI is older, and ANSI T1.617 Annex D is newer. Networks usually support one or the other.

•ANNEXA: ITU-T Q.933 Annex A

•ANNEXD: ANSI T1.617 Annex D Local In-channel Signaling.

•AUTOLMI: Automatically detects which LMI protocol is in use, in the following order: Annex D, LMI, Annex A, None.

•LMI: Pre-ANSI LMI protocol.

•NONE: No LMI protocol selected. If LMI is set to none, you are not required to configure the settings LMIN1, LMIN2, LMIN3, and LMIT1.

Default: AUTOLMI.

Maximum number of DLCI (P1)

Defines the maximum number of Permanent Virtual Connections (analogous to X.25 PVCs) that can be active simultaneously. Once allocated, each DLCI can be changed to reflect the DLCI assigned at subscription time.

Range: 1-8.

Default: 1.

Information field size (dN1)

Defines the maximum number of bytes of user data that can be contained in a Frame Relay frame.

Range: 19-4096.

Default: 1514.

Full status polling cycle (N1)

Defines the number of polling cycles before a Full Status Report is requested. A polling cycle is a Status Enquiry and Status message exchange. This setting determines the time the user device takes to recognize a change in status on a DLCI from the Frame Relay network. This may include the addition or deletion of a DLCI by the network.

Range: 1-255.

Default: 6.
