HH3C-BFD-STD-MIB
About this MIB
Upper layer protocols implement fast fault detection through the link layer. The fault detection time varies by link type, and failures might not be detected sometimes. POS has the fastest detection speed of approximately 50 milliseconds, which is used to measure fault detection time for other protocols.
BFD provides a general-purpose, standard, medium- and protocol-independent fast failure detection mechanism. BFD can uniformly and quickly detect the failures of the bidirectional forwarding paths between two devices for upper-layer protocols such as routing protocols and MPLS. BFD can provide detection measured in milliseconds, which is close to the detection time implemented by POS.
This document describes the following variables required to implement BFD:
· hh3cBfdGlobalObjects includes hh3cBfdVersionNumber (version number), hh3cBfdSysInitMode (session initialization mode), hh3cBfdSessNotificationsEnable (SNMP notifications switch), and hh3cBfdSessNumberLimit (session limit).
· hh3cBfdIfTable describes BFD interface information.
· hh3cBfdSessTable describes BFD session information.
· hh3cBfdSessStatTable describes BFD session statistics information.
· hh3cBfdSessPerfTable describes BFD session performance information.
· In hh3cBfdNotifications, hh3cBfdSessStateChange describes session state changes (from up to another state, or from another state to up), and hh3cBfdSessAuthFail describes authentication failure information.
HH3C-BFD-STD-MIB is based on draft-ietf-bfd-base-04.txt. This MIB is used for network management protocols in the Internet communities. It describes the objects used to configure or monitor bidirectional forwarding on devices supporting BFD.
