GR | The graceful restart (GR) feature ensures the continuity of packet forwarding when a protocol restarts. |
VRRP | The Virtual Router Redundancy Protocol (VRRP) can provide highly reliable default links when a device fails. |
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. Boot ROM validity check is not supported. Device management configuration involves mainly the following task: l Configuring device management |
NQA | Network Quality Analyzer (NQA) analyzes network performance, services and service quality by sending test packets, and provides network performance and service quality parameters such as jitter, TCP connection delay, FTP connection delay and file transfer rate. It is an enhancement and extension of the Ping tool. NQA configuration involves mainly the following tasks: l Configuring NQA tests l Configuring optional NQA parameters |
NTP | The Network Time Protocol (NTP) synchronizes timekeeping among distributed time servers and clients. NTP configuration involves mainly the following tasks: l Configuring NTP operation mode l Configuring the local clock as a reference source l Configuring optional parameters of NTP l Configuring access control rights l Configuring NTP authentication |
RMON | Remote Monitoring (RMON) 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. RMON configuration involves mainly the following task: l Configuring RMON |
SNMP | The 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. SNMP configuration involves mainly the following tasks: l Configuring basic functions of SNMP l Configuring traps |
File system management | The files used for device operation are stored in the storage device. A major function of the file system is to manage storage devices. File system management configuration involves mainly the following tasks: l Configuring file management l Configuring FTP/TFTP l Configuring TFTP |
System maintaining and debugging | For the majority of protocols and features supported, the system provides corresponding debugging information to help users diagnose errors. System maintaining and debugging configuration involves mainly the following tasks: l Configuring system maintaining and debugging l Configuring the ping and tracert commands |
Basic system configuration | l Performing basic system configurations |
Information center | As the system information hub, the information center classifies and manages system information. Information center configuration involves mainly the following task: l Configuring the information center |
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. User interface configuration involves mainly the following tasks: l Configuring asynchronous serial interface attributes l Configuring terminal attributes l Configuring modem attributes l Configuring a command to be auto-executed l Configuring a user privilege level l Configuring access restriction/supported protocols on VTY user interface(s) l Configuring redirection function on asynchronous serial interface(s) l Configuring the authentication mode at login |
HTTP | The Hypertext Transfer Protocol (HTTP) is used for transferring web page information across the Internet. The HTTP Security (HTTPS) refers to the HTTP protocol that supports the Security Socket Layer (SSL) protocol. HTTP configuration involves mainly the following tasks: l Configuring HTTP l Configuring HTTPS |
Track | The Track module is used to implement collaboration between different modules. The detection modules probe the link status and inform the Track module of the probe result so that the Track module changes the status of the Track object accordingly; when the status of the Track object changes, the Track module tells the application modules to deal with the change accordingly. l Configuring collaboration between the track module and NQA l Configuring collaboration between the track module and the application modules |
Hotfix | Hotfix can repair the software defect of the current version without rebooting the device. |
