2. View Switch Details
Nearest Switch
When diagnosing user issues, determining the connection point to the network is often the first step. The EtherScope II Series ES Network Assistant Generation 2 (ES2-LAN, ES2-PRO, ES2-PRO-SX/I) discovers the "Nearest Switch," identifying the slot and port you are connected to, helping you speed up troubleshooting, validate moves, or update documentation. After identifying the nearest switch, the EtherScope II can conveniently launch a web browser or Telnet session to configure the switch or check its details and port statistics.
Switch Port Diagnostics
View your switched/VLAN network to comprehensively identify problems at light speed. You can view the WLAN through wired-side switch port analysis. Point to any remote SNMP/RMON device and track the usage of remote interfaces.
Switch Scan
Continuously monitor the discovered nearest switch and one additional user-selected switch for high utilization and errors. View average and peak utilization, inbound/outbound traffic, packets, octets, errors, and speed for switch slots and ports. Select interfaces of interest and trend network traffic, or drill down to interface details.
3. Discover LAN
The EtherScope II Series ES Network Assistant Generation 2 (ES2-LAN, ES2-PRO, ES2-PRO-SX/I) typically organizes discovered devices by IP subnet, NetBIOS domain name, and IPX network. Subnet details include address range and subnet mask, while domain details can distinguish master browsers and domain controllers. Using an easy search function, you can search all networks using full or partial names, IP addresses, or MAC addresses to quickly pinpoint every occurrence of a device.
4. Discover VLAN
The EtherScope II Series ES Network Assistant Generation 2 (ES2-LAN, ES2-PRO, ES2-PRO-SX/I) identifies the VLANs configured on discovered switch interfaces for you. You can then drill down to view interface status and details of connected hosts, and analyze trends in interface data. If you are using a management VLAN, switches might not be found during the discovery process. However, with the EtherScope II, you can easily add switches as custom devices to get a complete picture of your switched network. The EtherScope II automatically determines the nearest switch, interface, and VLAN for each discovered device, simplifying problem resolution and tracking configuration changes.
5. Discover LAN Devices
The ES Network Assistant can discover up to 1000 devices and display switch and VLAN information indicating user connection locations. Saves time for network staff troubleshooting connectivity and congestion issues.
6. Check LAN Health
Identify key network statistics: Tri-color LEDs continuously update to show connection status, utilization level, collisions, errors, and transmission activity.
Network Health: View the utilization of the segment you are connected to for a quick overview of network activity.
Monitor Key Devices: Ping key devices to verify connectivity to user-defined devices (routers, servers, or switches).
Determine Network Capacity Trends and Needs: Switch port statistics and trend analysis reveal steady and bursty traffic, helping you and your staff quickly identify issues.
7. Analyze LAN Traffic
Increase network uptime. The ES Network Assistant views your network traffic statistics, including protocol information, top talkers, top broadcasters, and error sources. Identify and locate bandwidth-hungry devices, isolating them from the network if necessary. Analyze performance trends with baseline data reports.
8. Validate LAN Signaling
Validate Ethernet signaling to troubleshoot speed and duplex mismatches and auto-negotiation issues. Test 802.3af Power over Ethernet (PoE) links. The EtherScope Series II can emulate an 802.3af Powered Device (PD) to request and measure voltage on each pin.
9. Validate Cabling
Validate UTP and STP copper cable characteristics: length, impedance, shorts, opens, and miswires, etc. Use toner (optional) to identify remote jack outlets. Connect the DSP Fiber Optic Module (DSP-FOM) to the LAN port to measure optical power and cable loss.
10. Measure Performance
How do you know if new network equipment or a LAN/WAN link will deliver the performance you expect? Is their performance sufficient for successful data transfer, email, webinars, VoIP, and other applications? Are user complaints about a slow network valid? How will adding more users to your segment affect network performance? The RFC 2544/ITO option helps answer these questions. This option includes RFC 2544 and advanced tests for measuring Ethernet performance. It also includes a traffic generator. Use the RFC 2544 performance test to analyze network link performance based on widely accepted IETF recommended values. Use advanced tests to measure frame loss, jitter, and Bit Error Rate (BER) for in-depth network performance insight. Use the EtherScope II Series ES Network Assistant Generation 2 (ES2-LAN, ES2-PRO, ES2-PRO-SX/I) to measure the performance of twisted-pair or fiber optic (SX, LX, ZX) cabling systems, and to generate traffic at rates up to 1 Gbps.
RFC 2544 Testing
With RFC 2544 implementation, the EtherScope II Series ES Network Assistant Generation 2 (ES2-LAN, ES2-PRO, ES2-PRO-SX/I) offers the advantage of controlling test configuration and automating test execution, thereby improving test efficiency. Four RFC 2544 and three advanced tests are available: throughput, latency, frame loss and back-to-back frames, loss ratio, jitter, and Bit Error Rate (BER). Execute only the tests you need. For each test, use default configurations or customize test parameters to observe how traffic differences affect link performance. By adjusting these parameters, you can also control the time required to complete the tests. Perform a test suite involving one or more RFC 2544 or advanced tests. For each end-to-end performance test, specify the LAN or WAN link to test by defining a target device, and test the same link multiple times with different configurations to observe performance differences. Also, use multiple remote devices to test multiple links from a single location. Add "Pass/Fail" thresholds to each test so everyone can easily understand the results. Simply click the "Start" button to execute the entire test suite through an automated operation. Then view and save tabular and graphical results to document link performance.
Traffic Generator
Use the traffic generator to create different loads for testing network performance. You can configure the protocol to use, traffic type, frame size, rate, and utilization percentage. Then generate traffic for devices within the local network or for target devices outside the local network.
Source and Destination Test Equipment
Besides the traffic generator, other end-to-end performance tests require two test instruments: a source and a destination. RFC 2544 and advanced tests require one EtherScope Network Assistant as the source and another EtherScope Network Assistant or a LinkRunner Pro Packet Reflector as the destination. Use two EtherScope II Series ES Network Assistant Generation 2 (ES2-LAN, ES2-PRO, ES2-PRO-SX/I) for unidirectional (upstream/downstream) testing, or combine an EtherScope analyzer with a relatively inexpensive LinkRunner Pro Reflector for loopback testing. Throughput tests can use another EtherScope, an OptiView v4 Integrated Network Analyzer, or a OneTouch AT Network Assistant Generation 2 as the destination device. The throughput is then determined by the slower of the two instruments.
11. Test LAN Remotely
Troubleshoot from anywhere via the Web. When connected to your twisted-pair or fiber optic LAN, the EtherScope fully supports secure remote access control. Therefore, regardless of where testing is needed, simply have an EtherScope at the remote location, where personnel can easily connect it to the local network, and you can diagnose the remote location via a web browser. Enter the EtherScope's IP address in a web browser to take control and resolve issues quickly.
12. Measure RF Signal
Is the problem caused by co-channel interference? Is the signal strength too low to support all users? The wireless EtherScope Network Assistant continuously scans 2.4GHz and 5GHz frequencies, giving you clear insight into the range and performance of your WLAN. Drop-down menus include signal strength, signal-to-noise ratio (SNR), utilization, and other useful measurements, allowing you to choose which measurements to view. Quickly determine if access points are configured for the correct channel and if the environmental RF transmit power is correct.
13. Discover Wireless LAN
Who is using the network, and where are they? Are wireless clients concentrated in one area of the building, thereby reducing WLAN performance? The wireless EtherScope Network Assistant quickly identifies all wireless network access points and finds all associated clients. Insight into wireless network utilization helps you make better decisions when deploying and expanding access points to support actual usage patterns.
14. Identify High-Traffic Access Points/Clients
Quickly find users consuming the most bandwidth. Use the wireless EtherScope to identify the busiest access points and the most demanding wireless clients. Drill down into WLAN metrics such as FCS errors, crosstalk, and retries. Identify suspicious activity, determine the source of the problem, and resolve it quickly.
15. Discover Rogue Devices
Wireless security is a major concern, and wireless security policies are difficult to enforce. Use the wireless EtherScope to perform regular audits of the wireless environment. The wireless EtherScope automatically searches for rogue access points, unauthorized wireless bridges, mobile clients, and ad-hoc networks, enabling quick response and problem resolution.
16. WLAN Rogue Device Detection
Unauthorized "rogue" access points can open the corporate network to the outside world, compromising security. Use the wireless EtherScope's "Security Scan" function to find rogue access points, and use the "Locate" function to track them down. Using an external directional antenna with the EtherScope can speed up the location of target 802.11 devices by 75% compared to using a standard omnidirectional antenna. Rotate the antenna 360° and note the direction of the strongest signal on the graphical display. Follow the path of the strongest signal to locate the target device. Pointing the antenna up and down helps determine if the access point is in the ceiling, on the floor above, or the floor below, which is particularly useful in multi-story buildings. The handheld EtherScope is an ideal portable platform for detecting rogue devices. It is small, lightweight, rugged, and directly displays changes in wireless signal strength on its color touchscreen.
17. WLAN Authentication Login
The wireless EtherScope discovers whether infrastructure and client devices are using the correct authentication mechanism. Use the wireless EtherScope's login test tool to test and monitor EAP (Extensible Authentication Protocol) authentication. Use the wireless EtherScope to force a wireless client to disconnect from an access point, and monitor the EAP exchange between the client and the access point when the client re-authenticates on the network. Additionally, it can discover if and where interruptions occur in the EAP authentication process.
18. Survey RF Environment
Has the RF environment changed after installing access points? Is the WLAN coverage sufficient to support all users? Does the WLAN provide pervasive coverage sufficient to support seamless roaming? Use the wireless EtherScope to immediately capture baseline RF coverage data after installing wireless infrastructure, then compare historical data with periodic survey data. You can use this information to make minor adjustments to wireless access point transmit power, redeploy access points, or add new access points before changes in the RF environment affect the user community.
19. 802.1X Security
The wireless ES Network Assistant supports IEEE 802.1X authentication and dozens of EAP types for connection security to 10/100/1000 and wireless LANs. View the login process to troubleshoot network access and DHCP issues. Isolate the cause of connection problems to determine what needs to be fixed.
20. Detect Problems
Real-time detection and diagnosis. Automatically view information about your 10/100/1000 and wireless LANs. Once you connect the EtherScope II Series Network Assistant to the network, it begins testing and displays real-time results for devices, networks, and problems. Navigate through intuitive menus to quickly access in-depth views of the network. On your LAN, find duplicate IPs, duplex mismatches, and DHCP failures. Monitor switch port statistics, identify and track all VLAN devices. Drill down into the problem log to evaluate each error, warning, and informational message. On your WLAN, detect TX percentage, retries, rates, and potential security risks.
21. Document Network Information
Document your LAN and WLAN status using XML-encoded reports. Recorded content includes network attributes, baseline performance, device inventory, traffic statistics, RF metrics, etc.
22. Validate LAN Services
The Service Performance tool verifies the existence of key network services and measures their responsiveness. Choose from six network services: DHCP, DNS, Email, File, WINS, and Web (HTTP). Add "Pass/Fail" thresholds for each service. The "Pass/Fail" assessment makes it easy for everyone to understand the test results. Save test configurations as scripts for future use or sharing with team members. Configure the tests, then click the "Start" button to initiate a series of automated service performance tests. View test results in tabular and graphical formats. Save results for archiving and as part of a LAN validation report.
