Features Description
Smart Link
Smart Link is a solution for active-standby link redundancy backup and
rapid transition in dual-uplink networking. This document describes:
z Smart Link Overview
z Configuring a Smart Link Device
z Configuring an Associated Device
Monitor Link
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:
z Monitor Link Overview
z Configuring Monitor Link
RRPP
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:
z RRPP overview
z Creating an RRPP Domain
z Configuring Control VLANs
z Configuring Protected VLANs
z Configuring RRPP Rings
z Configuring RRPP Ports
z Configuring RRPP Nodes
z Activating an RRPP Domain
z Configuring RRPP Timers
z Configuring an RRPP Ring Group
DLDP
In the use of fibers, link errors, namely unidirectional links, are likely to
occur. DLDP is designed to detect such errors. This document describes:
z DLDP Introduction
z Enabling DLDP
z Setting DLDP Mode
z Setting the Interval for Sending Advertisement Packets
z Setting the DelayDown Timer
z Setting the Port Shutdown Mode
z Configuring DLDP Authentication
z Resetting DLDP State
Ethernet OAM
Ethernet OAM is a tool monitoring Layer-2 link status. It helps network
administrators manage their networks effectively. This document
describes:
z Ethernet OAM overview
z Configuring Basic Ethernet OAM Functions
z Configuring Link Monitoring
z Enabling OAM Loopback Testing
Connectivity Fault
Detection
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:
z Connectivity Fault Detection Overview
z Basic Configuration Tasks
z Configuring CC on MEPs
z Configuring LB on MEPs
z Configuring LT on MEPs
