3What this role really is

A Network Support Assistant helps keep computer networks running, sorting routine problems and knowing when to pass on trickier ones.

4What you'd actually use

The tools this job runs on, and how well you'd need to know each one.

SolarWinds NPM / Nagios / Zabbix (Network Monitoring) Intermediate

Reading dashboards, acknowledging alerts, performing basic health checks, and investigating initial alert triggers. You'll be spotting 'flapping ports' before they become outages.

ServiceNow / Jira Service Management (ITSM & Ticketing) Intermediate

Managing your personal ticket queue, updating ticket status, following existing knowledge base articles to resolve issues, and creating new 'CRs' for changes.

Wireshark (Packet Analysis) Basic

Capturing traffic on a specific interface, applying basic display filters (e.g., by IP address or protocol) to confirm connectivity or identify basic application issues.

PuTTY / SecureCRT / Windows Terminal (Remote Access & CLI) Intermediate

Using saved sessions to connect to network devices, executing pre-vetted `show` commands (e.g., `show ip interface brief`), and making basic configuration changes.

Confluence / NetBox (Documentation) Intermediate

Finding and following existing documentation (e.g., network diagrams, runbooks), and creating/updating network diagrams (using tools like Visio/Draw.io) and runbooks for common procedures. You'll keep NetBox up to date with IPAM data.

Splunk / Graylog (Log Management) Basic

Performing basic searches on an IP address or hostname to find related events (e.g., firewall denies, switch port status changes) to aid in troubleshooting.

5What you get to decide, and how that grows

Power in a job isn't your title. It's what you're allowed to decide. Here's how it grows as you move up.

The choiceComing in Where you are nowThe step above
Troubleshooting Approach for Incidents Follows documented runbooks and escalates if the issue isn't covered or if unsure. Chooses appropriate troubleshooting methodology (e.g., top-down, bottom-up) for routine problems; escalates novel or complex issues after initial investigation. Defines troubleshooting methodologies for new technologies; leads complex incident resolution; makes real-time decisions during major outages.
Network Configuration Changes Executes pre-approved, simple changes under direct supervision (e.g., adding a port to a specific VLAN). Proposes and implements routine configuration changes (e.g., new switch port, basic firewall rule) with peer review and formal 'CR' approval. Designs and implements significant network changes (e.g., new routing protocols, VPN tunnels); approves changes for junior staff; accountable for change success.
Documentation Updates Finds and follows existing documentation; updates minor details under guidance. Creates new knowledge base articles for recurring issues; updates network diagrams (using Visio/Draw.io) and runbooks for common procedures. Establishes documentation standards; reviews and approves documentation from junior staff; ensures documentation supports audit requirements.

6How you'll be judged

The scoreboard, and what is not on it. The hard targets, how often each is actually looked at, and the quiet signals that never reach a dashboard.

Mean Time to Resolution (MTTR) for P3 Tickets
How long it takes you, on average, to resolve a standard priority 3 network incident from the moment it hits your queue.
Target · < 4 hours

You pick up a 'printer not connecting' ticket at 10:00, diagnose a misconfigured switch port, fix it, and close the ticket by 11:30. That's 1.5 hours, contributing positively to your MTTR.

First Contact Resolution (FCR) Rate
The percentage of network issues you resolve on your first interaction with the user or without needing to escalate to a more senior engineer.
Target · > 75% for common issues

A user reports 'no network access'. You guide them through basic troubleshooting, identify a faulty network cable, and they're back online without you needing to pass it up the chain. That counts as an FCR.

SLA Compliance for Assigned Tickets
The percentage of your assigned network incident and service request tickets that you resolve within their agreed-upon service level agreement.
Target · 95% of tickets resolved within SLA

If a P2 ticket has a 24-hour resolution SLA, you need to have it fixed and closed before that 24-hour mark hits. Consistently hitting this shows you're managing your workload well.

Knowledge Base Contribution
The number of new or updated knowledge base articles you create or improve based on recurring issues you've resolved.
Target · 2 new or updated articles per month

You keep seeing the same VPN connectivity issue. You write a clear, step-by-step guide for users or IT Service Desk staff to follow, reducing future tickets on that topic.

Quality of Troubleshooting & Documentation
How thoroughly you investigate issues, the clarity of your thought process in tickets, and the completeness of your documentation.
  • Your tickets consistently show a logical troubleshooting path (e.g., 'Checked Layer 1, then Layer 2, then Layer 3'). Colleagues can easily understand your notes and follow your steps. Your manager rarely needs to ask for more detail on a closed ticket.
Proactive Issue Identification
Your ability to spot patterns in recurring issues or monitoring alerts that might point to a bigger problem, even if it's not explicitly assigned to you.
  • You flag up that 'flapping port' alert that's been happening every Tuesday for the last month. You notice a cluster of 'can't get a DHCP lease' tickets from a specific office and suggest investigating the local DHCP server, rather than just restarting user machines.
Team Collaboration & Support
How well you work with the rest of the IT team, especially the Service Desk, and your willingness to help out junior colleagues.
  • The Service Desk team often praises your clear communication. You're happy to walk a new joiner through a common troubleshooting scenario. You offer to help a colleague who's swamped with tickets without being asked.

7Would you like it

Both sides. What people enjoy, and what grinds them down.

What people enjoy
Solving Puzzles

You get a kick out of taking a vague problem ('the Wi-Fi is rubbish') and breaking it down into smaller pieces until you find the exact culprit. The satisfaction of a tricky diagnosis and a successful fix is what gets you going.

You spend an hour methodically tracing a 'flapping port' issue back to a faulty patch cable in a dusty comms cabinet, and you feel a real sense of accomplishment.

Keeping Things Running Smoothly

You genuinely care about uptime and reliability. You're motivated by the idea that your work directly contributes to everyone else being able to do their job without interruption. You're the unsung hero of the office.

You proactively spot a potential 'broadcast storm' building up from monitoring alerts and fix it before anyone even notices a slowdown, feeling good that you've averted disaster.

Continuous Learning & Mastery

You're always looking to deepen your understanding of network technologies. You'll spend your lunch break reading up on a new routing protocol or trying to understand *why* 'it's always DNS'.

After resolving an issue, you'll spend extra time researching the underlying technology, not just the quick fix, to make sure you truly understand it for next time.

What frustrates people
  • The 'Network is Slow' Fallacy: Spending hours proving that 99% network uptime and low latency mean the problem is actually the under-resourced application server, yet still being seen as the bottleneck.
  • Vague Tickets: Receiving tickets with the subject 'No internet' from a user in a 10,000-person company with no additional details (no username, no asset tag, no location).
  • Documentation Debt: Trying to troubleshoot a critical outage using a network diagram that was last updated three years and two office moves ago, or having to do 'cable management archaeology' in a rat's nest.
  • On-Call Nightmares: Being woken up at 3 AM for an automated alert that turns out to be a non-production server being rebooted by another team that didn't inform anyone.
  • The 'Quick Fix' Mentality: Being pressured to implement a quick, unvetted change that you know will cause problems down the line, rather than following proper 'Change Management Discipline'.
What this role does not give you
  • A predictable, 9-to-5 schedule every single day. Outages don't care about your plans.
  • A role where you only work on exciting, cutting-edge projects. There's a lot of routine maintenance and troubleshooting.
  • A quiet, isolated environment. You'll be talking to people constantly, often under stress.
  • The ability to completely ignore process. We have processes for a reason, and you'll be expected to follow them, even when they feel clunky.

8Who you work with

This role directly impacts our company's day-to-day operational efficiency. If the network isn't working, neither are our people. You're keeping the lights on, digitally speaking, and making sure our core business functions can run without interruption. You're also building up our knowledge base, which helps everyone resolve issues faster in the future.

Inside the business
  • Your Manager (Senior Network Support Analyst)
  • IT Service Desk Team
  • Server Operations Team
  • Internal Business Users (your 'customers')
Outside the business
  • Internet Service Providers (ISPs)
  • Network Hardware Vendors (e.g., Cisco, Juniper support)

9What you need before you start

Not a wish list. The things you would be expected to already have.

  • At least 2 years of hands-on experience in a network support or IT support role with a strong network focus.
  • Proven ability to troubleshoot common network issues (e.g., connectivity, Wi-Fi, basic routing) independently.
  • Demonstrable understanding of the OSI model and TCP/IP stack.
  • Experience working with an ITSM ticketing system (e.g., ServiceNow, Jira Service Management).
  • A solid grasp of IP subnetting (IPv4 is a must, IPv6 is a bonus).
  • Experience using command-line interfaces (CLI) for network device configuration and troubleshooting.

10What to practise next

Where the job is going, and what to do about it starting this week.

Advanced Troubleshooting & Problem Management

As networks become more complex, the easy problems get automated away. You'll be left with the really tricky, intermittent issues that require deeper analysis and a more structured approach to 'Problem Management'—finding and fixing the root cause, not just the symptom.

Root Cause Analysis (RCA) techniques · Performance baselining · Intermittent fault diagnosis · Packet flow analysis (deep dive with Wireshark)

  • This week: Focus on writing detailed, logical troubleshooting steps in every ticket, even for simple issues.
  • This month: Pick one recurring network problem and try to perform a full RCA, even if it's just for your own learning.
  • Month 2: Get comfortable with advanced Wireshark filters and start analysing packet captures for real-world issues.
  • Month 3: Shadow a Senior Analyst during a complex incident or problem management meeting to see how they approach it.

Quick win: Whenever you fix a problem, ask yourself 'Why did this happen?' at least three times. It's a simple habit that builds a problem-solving mindset.

Cloud Networking Fundamentals (Azure/AWS/GCP)

More and more of our infrastructure, and our customers' infrastructure, is moving to the cloud. You won't just be supporting on-premise networks; you'll need to understand how virtual networks, firewalls, and VPNs work in cloud environments. It's a different beast, but the core networking principles still apply.

Virtual Private Clouds (VPCs) / Virtual Networks (VNets) · Cloud routing tables & security groups · Site-to-site VPNs / ExpressRoute / Direct Connect · Cloud-native load balancers & DNS

  • This week: Sign up for a free tier account on Azure or AWS and deploy a basic virtual network.
  • This month: Complete an introductory course on cloud networking fundamentals (e.g., Azure AZ-900 or AWS Cloud Practitioner).
  • Month 2: Try to configure a simple site-to-site VPN between your virtual network and a simulated on-premise network.
  • Month 3: Read up on common cloud network troubleshooting scenarios and best practices.

Quick win: Familiarise yourself with the basic terminology of one cloud provider (e.g., AWS EC2, S3, VPC). Just knowing the names helps you understand conversations.

11Staying current once you are in

What people here do to keep up
  • Regularly engage with industry blogs and forums (e.g., Packet Pushers, Reddit's r/networking) to stay current on new technologies and troubleshooting tips.
  • Attend webinars or virtual conferences from vendors like Cisco, Juniper, or Fortinet to learn about their latest offerings.
  • Participate in online labs or build a home lab to experiment with new network configurations without impacting production.
  • Contribute to open-source networking projects or community discussions if you're feeling adventurous.
  • Take on more complex troubleshooting tasks and proactively seek feedback from senior colleagues.

Working with AI on the job

Working with AI

Where AI is starting to help

Let's be real, network support can be a grind. The same old tickets, the endless log searches, the 'it's always DNS' jokes that aren't funny anymore. But what if you could ditch the drudgery and focus on the really interesting stuff? Our AI Productivity Hub is here to help you do just that.

For a Network Support Assistant, AI isn't about replacing you; it's about making you a superhero. Imagine having an intelligent assistant that helps you spot problems before they happen, diagnoses issues faster than ever, and even drafts your incident reports. That's the power we're putting in your hands, letting you reclaim hours every week.

Proactive Fault Detection

Use an AI-powered log analyser (like Splunk's ITSI or Datadog) to constantly analyse telemetry from routers, switches, and firewalls. It can identify subtle patterns that precede an outage (e.g., rising CRC errors, unusual latency spikes) and create a predictive ticket before users are impacted. You'll be fixing problems before anyone even notices them.

Root Cause Analysis Accelerator

During a major incident, feed alerts and logs from multiple systems (monitoring, syslog, application performance) into an AIOps platform. The AI correlates the events and suggests the most likely root cause, pointing you directly to the faulty device instead of having to check 10 different systems manually. This means less time on 'war room' calls and faster fixes.

Instant Command & Config Syntax

Use a specialised AI assistant (like a fine-tuned LLM) as a 'co-pilot'. Ask it questions like, 'What's the correct command syntax to configure a BGP peer on a Juniper MX204 running Junos 21.4?' or 'Generate a standard ACL to block traffic from this subnet.' It provides instant, accurate answers, eliminating time spent searching through vendor documentation. No more 'it's always DNS' searches for command syntax.

Automated Incident Communication

After resolving an incident, use an AI tool to draft the initial post-mortem or user-facing communication. It can summarise the ticket timeline, translate technical jargon ('asymmetric routing issue') into plain English ('a configuration mismatch caused data to be misdirected'), and structure the report, leaving you to simply review and refine the details. Less admin, more actual network work.
