Network Maintenance Checklist: A Guide for IT Professionals

Network Maintenance Checklist. A well-maintained network is essential for the smooth operation of any organization. By regularly performing preventive maintenance tasks, you can help to ensure that your network is stable, secure, and performant. This guide will provide you with a comprehensive checklist of network maintenance tasks that you can use to keep your network running at its best.

Step 1: Pre-Maintenance Preparation

  1. Assessment of Network Architecture

Before you begin any maintenance tasks, it’s important to assess the current state of your network architecture. This includes reviewing your network diagrams, documentation, and any recent changes that have been made to the network.

  1. Documentation Review

Make sure that you have up-to-date documentation of your network, including network diagrams, configurations, and vendor information. This documentation will be invaluable when troubleshooting issues or making changes to the network.

Step 2: Security Checks

  1. Firewall and Intrusion Prevention System (IPS) Audit

Regularly review the configuration of your firewall and IPS to ensure that they are up-to-date and properly configured. Check for any vulnerabilities or misconfigurations that could be exploited by attackers.

  1. Antivirus and Anti-Malware Updates

Keep your antivirus and anti-malware software up to date with the latest versions. This will help to protect your network from viruses, malware, and other threats.

  1. Patch Management

Implement a patch management system to automatically apply patches to your network devices. This will help to protect your systems from known vulnerabilities.

Step 3: Hardware and Software Maintenance

  1. Server and Router Health Check

Regularly check the health of your servers and routers to ensure that they are operating properly. This includes checking for CPU, memory, and disk usage, as well as any error logs.

  1. Switch and Access Point Configuration

Review the configuration of your switches and access points to ensure that they are properly configured for your network. This includes checking for VLANs, security settings, and QoS (Quality of Service) settings.

Step 4: Performance Monitoring

  1. Bandwidth and Traffic Analysis

Monitor the bandwidth and traffic patterns on your network to identify any potential bottlenecks or anomalies. This will help you to identify and troubleshoot network performance issues.

  1. Network Latency

Monitor the network latency to ensure that it is within acceptable limits. High latency can cause delays in data transmission and can have a negative impact on the user experience.

Step 5: Backup and Recovery

  1. Data Backup Verification

Verify that your data backups are complete and up-to-date. This will help you to protect your data from loss in the event of a disaster.

  1. Disaster Recovery Plan (DRP)

Review your Disaster Recovery Plan to ensure that it’s up-to-date and that you have a plan in place to recover your network in the event of a disaster.

Step 6: Post-Maintenance Documentation

  1. Update Network Documentation

Update your network documentation to reflect any changes that have been made during the maintenance process. This includes documentation of configuration changes, patch installations, and any other relevant information.

  1. Incident Reporting

If you encounter any issues during the maintenance process, create an incident report to document the problem, the steps you took to resolve it, and any lessons learned.


By following this comprehensive checklist of network maintenance tasks, you can help to ensure that your network is always running smoothly and efficiently. By proactively addressing potential issues, you can prevent downtime and protect your data.

Alternatively, many companies choose to outsource these tasks to specialists like Evernex through a third-party maintenance (TPM) agreement. This helps organizations free up time and resources to focus on their work and provides the peace of mind of knowing that a team of experts is in charge of optimizing hardware performance and ensuring maximum uptime through both preventive maintenance and quick repairs in case of a breakdown.

The benefits of third-party maintenance also extend to considerable savings and an increase in sustainability. This is due to the fact that, with TPM, the useful life of equipment is extended beyond manufacturer-mandated EOSL (end of service life) dates and refurbished spare parts are used to optimize the performance of hardware.
