Module: CXLapBD-MIB

OID (symbolic): CXLapBD-MIB::lapbdMacSapLapType

OID (numeric): 1.3.6.1.4.1.495.2.1.6.27.20.1.5

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Determines the type of link access procedure provided by this MAC SAP (service access point): LAPB or LAPD. It also determines the number of data link SAPs that are automatically created and associated with this SAP.

If the value of lapbdMacSapLapBProtocolFlavor is set to 'v8022', then the value for this object is forced to 'lapb', regardless of its setting. This object returns to its original value only when lapbdMacSapLapBProtocolFlavor is set to 'standard'.

Options: lapb (1): Defines a LAPB service access point and creates one associated data link SAP.

lapd (2): Defines a LAPD service access point and creates three associated data link SAPs.

Default Value: lapb (1)

Related Objects: lapbdMacSapLapBProtocolFlavor

Configuration Changed: administrative

What is lapbdMacSapLapType?

Selects whether this SAP runs LAPB (default) or LAPD framing, which also decides how many data-link SAPs get auto-created underneath it - one for LAPB, three for LAPD. An admin terminating an ISDN D-channel would set this to lapd(2), while a leased-line X.25 circuit stays at the lapb(1) default.
