usdFt1IfLowerIfIndex

Module: Unisphere-Data-FRACTIONAL-T1-MIB

OID (symbolic): Unisphere-Data-FRACTIONAL-T1-MIB::usdFt1IfLowerIfIndex

OID (numeric): 1.3.6.1.4.1.4874.2.2.6.1.2.1.3

Node type: OBJECT-TYPE

Type: InterfaceIndexOrZero

Access: read-create

Description: The ifIndex of a DS1 interface over which this FT1 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 usdFt1IfLowerIfIndex?

usdFt1IfLowerIfIndex identifies the ifIndex of the underlying DS1 interface that this fractional T1 interface is layered over, with a value of zero meaning no layering is configured. An admin sets this when creating an FT1 interface to bind it to a specific physical DS1 circuit from which it will carve out individual DS0 time slots. For example, an admin sets usdFt1IfLowerIfIndex to the ifIndex of a T1 port to carve a fractional T1 sub-interface out of that circuit's channel capacity.
