juniPppSummaryPppLinkIfLowerLayerDown
Module: Juniper-PPP-MIB
OID (symbolic): Juniper-PPP-MIB::juniPppSummaryPppLinkIfLowerLayerDown
OID (numeric): 1.3.6.1.4.1.4874.2.2.11.1.7.24
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: The total number of PPP Link interfaces in the system with an operational state of lowerLayerDown(7).
What is juniPppSummaryPppLinkIfLowerLayerDown?
This gauge reports the total number of PPP Link interfaces in the system with an operational state of lowerLayerDown(7). It isolates PPP-layer outages that are actually caused by the physical or logical interface underneath (such as a downed DSL or Ethernet circuit) rather than by PPP negotiation itself. For example, a spike in juniPppSummaryPppLinkIfLowerLayerDown during a fiber cut would explain a wave of PPP interfaces going down without any PPP-specific fault.
