GR Overview | Graceful Restart ensures the continuity of packet forwarding when a routing protocol restarts. l Basic concepts in GR l GR communication procedure l GR mechanism for several commonly used protocols |
VRRP | Deploying VRRP on multicast and broadcast LANs such as Ethernet, you can ensure that the system can still provide highly reliable default links without changing configurations when a device fails and prevent network interruption due to a single link failure. l VRRP configuration for IPv4 l VRRP configuration for IPv6 |
HA | High Availability (HA) feature can be used to achieve a higher degree of system availability. l Introduction to HA l HA configuration |
Device Management | Through the device management function, you can view the current working state of a device, configure running parameters, and perform daily device maintenance and management. l Device management configuration |
NQA | Network Quality Analyzer (NQA) analyzes network performance, services and service quality through sending test packets, and provides you with network performance and service quality parameters. l NQA server configuration l Enabling the NQA client l NQA test group configuration l Collaboration function configuration l Scheduling of NQA test group |
NTP | Network Time Protocol (NTP) synchronizes timekeeping among distributed time servers and clients. l NTP operation mode configuration l Configuration of local clock as a reference source l NTP optional parameters configuration l Access-control rights configuration l NTP authentication configuration |
RMON | Remote Monitoring (RMON) provides an efficient means of monitoring subnets and allows SNMP to monitor remote network devices in a more proactive and effective way. It reduces traffic between network management station (NMS) and agent, facilitating large network management. l RMON configuration |
SNMP | Simple Network Management Protocol (SNMP) offers a framework to monitor network devices through TCP/IP protocol suite. It provides a set of basic operations in monitoring and maintaining the Internet. l SNMP basic functions configuration l Trap configuration |
File System Management | A major function of the file system is to manage storage devices. l File system management configuration l FTP configuration l TFTP configuration |
System Maintaining and Debugging | For the majority of protocols and features supported, the system provides corresponding debugging information to help users diagnose errors. l Introduction to system maintaining and debugging l System maintaining and debugging operations l System maintaining examples |
Basic System Configuration | l Basic system configuration |
Information Center | Acting as the system information hub, information center classifies and manages system information. l Information center configuration |
User Interface | User interface view is a feature that allows you to manage asynchronous serial interfaces that work in flow mode. By operating under user interface view, you can centralize the management of various configurations. l Asynchronous serial interface attributes configuration l Terminal attributes configuration l Modem attributes configuration l Auto-execute command configuration l User privilege level configuration l Configuration of access restriction on VTY user interfaces l Configuration of authentication mode at login |
MAC Address Table Management | Each entry in the MAC address table indicates the MAC address of a connected device, to which interface this device is connected and to which VLAN the interface belongs. l MAC address table management configuration |
Clock Monitoring | Clock monitoring module is responsible for providing highly-precise, highly-reliable SDH (synchronous digital hierarchy) line interface 38.88 MHz clock signals for different LPUs (line processing unit). It implements such functions as input clock source automatic selection, software phase-lock, and real-time monitoring of the clock status of the interface card. The module supports hardware reset of the clock card. l Configuration of clock monitoring module of the SRPU l SSM reference source configuration l Input port of the line clock configuration |
Track | The Track module is used to implement collaboration between different modules. The collaboration here involves three parts: the application modules, the Track module, and the detection modules. l Track overview l Configuration of collaboration between the track module and the detection modules l Configuration of collaboration between the track module and the application modules |
