GR Overview
In the use of fibers, link errors, namely unidirectional links, are likely to
occur. DLDP is designed to detect such errors. This document describes:
DLDP Introduction
Enabling DLDP
Setting DLDP Mode
Setting the Interval for Sending Advertisement Packets
Setting the DelayDown Timer
Setting the Port Shutdown Mode
Configuring DLDP Authentication
Resetting DLDP State
Ethernet OAM is a tool monitoring Layer-2 link status. It helps network
administrators manage their networks effectively. This document
describes:
Ethernet OAM overview
Configuring Basic Ethernet OAM Functions
Configuring Link Monitoring
Enabling OAM Loopback Testing
Connectivity fault detection is an end-to-end, per-VLAN link-layer OAM
mechanism for link connectivity detection, fault verification, and fault
location. This document describes:
Connectivity Fault Detection Overview
Basic Configuration Tasks
Configuring CC on MEPs
Configuring LB on MEPs
Configuring LT on MEPs
Bidirectional forwarding detection (BFD) provides a single mechanism to
quickly detect and monitor the connectivity of links in networks.
Configuring BFD Basic Functions
Configuring Protocol-based BFD
Enabling Trap
The track module is used to implement collaboration between different
modules through established collaboration objects. The detection
modules trigger the application modules to perform certain operations
through the track module. This document describes:
