Smart Link is a solution for active-standby link redundancy backup and
rapid transition in dual-uplink networking. This document describes:
Smart Link Overview
Configuring a Smart Link Device
Configuring an Associated Device
Monitor link is a port collaboration function used to enable a device to be
aware of the up/down state change of the ports on an indirectly connected
link. This document describes:
Monitor Link Overview
Configuring Monitor Link
RRPP is a link layer protocol designed for Ethernet rings. RRPP can
prevent broadcast storms caused by data loops when an Ethernet ring is
healthy, and rapidly restore the communication paths between the nodes
after a link is disconnected on the ring. This document describes:
RRPP overview
Creating an RRPP Domain
Configuring Control VLANs
Configuring Protected VLANs
Configuring RRPP Rings
Configuring RRPP Ports
Configuring RRPP Nodes
Activating an RRPP Domain
Configuring RRPP Timers
Configuring an RRPP Ring Group
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
