usdHdlcIfLowerIfIndex

Module: Unisphere-Data-HDLC-MIB

OID (symbolic): Unisphere-Data-HDLC-MIB::usdHdlcIfLowerIfIndex

OID (numeric): 1.3.6.1.4.1.4874.2.2.9.1.2.1.3

Node type: OBJECT-TYPE

Type: InterfaceIndexOrZero

Access: read-create

Description: The ifIndex of an interface over which this HDLC interface is to be layered. A value of zero indicates no layering. An implementation may choose to require that a nonzero value be configured at entry creation.

What is usdHdlcIfLowerIfIndex?

This value is the ifIndex of the interface this HDLC interface is layered over, such as a serial or HSSI port, with zero meaning no layering. Admins set it at interface creation to bind the new HDLC framing layer to its underlying physical or logical transport interface. For example, setting it to the ifIndex of a T1 controller would stack this HDLC interface directly on top of that T1 link.
