Packet capture parameters (other than the mode) are saved in NVRAM.Įnabling the packet capture feature can create a security issue: Unauthorized clients may be able to connect to the WAP device and trace user data. If the WAP device resets, the capture mode is disabled and then you must enable it again to resume capturing traffic. For example, if the Wireshark IP port is configured to be 58000, then this capture filter is automatically installed on the WAP device: not port range 58000-58004ĭue to performance and security issues, the packet capture mode is not saved in NVRAM on the WAP device. To avoid a traffic flood caused by tracing the packets, the WAP device automatically installs a capture filter to filter out all packets destined to the Wireshark application. ![]() Depending on the location of the Wireshark tool, the traffic can be sent on an Ethernet interface or one of the radios. In remote capture mode, traffic is sent to the computer running Wireshark through one of the network interfaces. !(wlan.fc.type_subtype = 8 | | wlan.fc.type = 1)Īll traffic to and from a specific client: Some examples of useful display filters are: Traffic on specific Basic Service Set IDs (BSSIDs). You can set up a display filter to show only: When you are capturing traffic on the radio interface, you can disable beacon capture, but other 802.11 control frames are still sent to Wireshark. We recommend that if you do not use the default port use a port number greater than 1024. ![]() Verify that you have four consecutive port numbers available. Remember not to just say that you used them, but also show the impact you had with them, for instance, “Implemented Juniper Junos for optimizing company network routing, improving data traffic efficiency by 20%.The system uses four consecutive port numbers, starting with the configured port for the remote packet capture sessions. ![]() Mention specific network hardware and software systems you’re familiar with, such as OpenVPN or Juniper Junos.Discuss your past disaster recovery strategies, supporting them with figures, such as recovery time, that showcase your impact on the organization’s business continuity. Network failures do occasionally happen, and your ability to quickly recover from one is vital.Highlight your disaster recovery planning.Most roles won’t require them, but they demonstrate a high level of knowledge and commitment to networking and are worth drawing attention to. If you have relevant certifications like the CCNP, CCIE, or CompTIA Network+, be sure to display them on your resume.Include figures that show the results of your work, such as the percentage drop in security issues. Show recruiters your security expertise by discussing measures you’ve implemented to protect against threats, for instance, firewalls or VPNs. Network security is a major concern for most organizations.This gives hiring managers more insight into your exact skill set. For instance, mention how you leveraged load balancing or bandwidth management to improve network efficiency by 15%. Instead of simply stating that you’ve improved network performance, go the extra mile by mentioning strategies you’ve used to get there.Elaborate on your optimization strategies.Top 5 Tips for Your Senior Network Engineer Resume Led a network virtualization initiative, resulting in a 22% drop in company-wide hardware costs.Led a team of 6 network engineers to roll out a company-wide network security upgrade, reducing security incidents by 43%. ![]() Leveraged Wireshark to conduct proactive troubleshooting and regular maintenance, reducing network downtime by 27%.Oversaw the implementation of a new network infrastructure, leading to a 40% improvement in system performance.Here are a few examples of quantifying your accomplishments: However, specifying that you leveraged SolarWinds to reduce network downtime by 25% and optimize bandwidth utilization by 20% places you firmly above candidates who don’t include figures to bolster their impact. By including concrete figures, you reaffirm your skills and experience, raising your profile in the eyes of a recruiter.įor instance, most senior network engineers use tools like SolarWinds Network Performance Monitor to ensure efficient network operations. In your line of work, your objectives and achievements are easy to quantify-and that’s the best way to underscore your impact. Sample senior network engineer work experience bullet pointsĪs a senior network engineer, you maintain and upgrade network security and systems, monitor performance, and identify problems before they can evolve into a catastrophe.
