Routine maintenance consists of device environment maintenance and device software maintenance.
Hardware running environment: The hardware running environment refers to the device room, power supply, and heat dissipation environment. This is the basic condition for the running of the device. For the maintenance of the device environment, the personnel needs to visit the site or even use some professional tools to observe and measure the device environment.
Device software running status: The running status of the device software is closely related to the specific services running on the device. Huawei datacom devices use the universal VRP platform. Network engineers should master the common maintenance commands of the VRP platform.
To maintain the device software, you can perform operations on site or remotely. You can use the display commands of the device to implement the maintenance.
Routine maintenance is a planned routine. Therefore, it is necessary to sort out a checklist for each project. For details about the checklist for different network devices, see the corresponding product documentation.
1. Check the device environment. ·Focus on temperature, humidity, and cleaning.
·Record and provide feedback in a timely manner, and ask professionals to handle difficult problems.
·Recommended execution period: Every day
2.Checking Basic Device Information ·Focus on version information, startup information, license information, and storage space.
·Record and provide feedback in a timely manner, identify the cause, and make a rectification plan.
·Recommended execution period: Weekly/Monthly
3. Check the running status of the device. ·Focus on alarm information, such as board, power supply, fan, temperature, CPU, and memory.
·Record and provide feedback in a timely manner. Contact the supplier to handle the device hardware temperature problems in time.
·Recommended execution period: Weekly/Monthly
4. Check the device port content. ·Pay attention to error statistics, duplex mode, and traffic statistics.
·Record and provide feedback in a timely manner. If any exception is found, analyze the cause in time.
·Recommended execution period: Weekly/Monthly
5. Check the service running status. ·Focus on the content related to the running services, such as multicast, OSPF, and BGP.
·Record and provide feedback in a timely manner. If any exception is found, analyze the cause in time.
·Recommended execution period: Weekly/Monthly
6. Software and Configuration Backup ·The purpose of backup is to restore network functions in extreme cases.
·Recommended execution period: Weekly
Most software operations can be performed through the NMS software. The NMS can be used to manage the alarms, performance, and configuration of devices, and generate reports. The eSight is recommended.
