The smallest size Gigabit Ethernet Test Set in the market, designed with powerful features and flexibility for your network trouble-shooting and verification needs within your budget.

The GiLaner Key Features
ARP Monitoring
  • Intercept ARP Spoofing/Attack/Poison
  • Intercept IP Conflict
  • Incoming ARP Packet Analysis
  • Protect ARP Cache
  • Active Defence
  • Trace Attacker
Link Status/Control & Connectivity Test
  • Support PING function for connectivity detection to any remote device in the network.
  • Support Fixed IP or DHCP mode for acquiring IP address.
  • Able to monitor or force the link status for its duplex mode (full or half), link speed (10, 100, 1000 Mbps), TX/RX pair in the cable, link quality, flow control status & auto-negotiation capability.
  • Able to shutdown the tester at user specified interval when not in operation.
  • Able to FLASH remote port LED for port identification.
  • Able to do ARP scan to search all the devices in the specified network for its MAC address, IP address and the associated host name.
Upstream/Downstream Traffic Flow
  • With two GiLaner connected to the network, the system can perform the upstream and downstream traffic flow simultaneously at various different rate.
  • This is a great feature in XDSL/FTTx application for bi-directional bandwidth simulation and verification.
RFC2544 Benchmarking Tests
  • The RFC2544 definition describes six standard tests that are used to measure and report the performance characteristics of network equipment. GiLaner can support the throughput, frame loss rate, back-to-back frames, and latency tests.
Cable Test & Fiber Diagnostic
  • Able to measure the UTP & STP cable length up to 150 meters long for OPEN/SHORT status. When SFP transceiver with Diagnostic Monitoring Interface is used, the tester can display the TX/RX power, temperature, Laser Bias Current, & voltage for quick diagnostic on the fiber link.
Test Report Generation
  • Able to record up to 80 sets of report by entering test date, test person, filename, and test site.
  • Each report can be exported to PC in ASCII text format at the touch of a button.
Flash Port
  • Able to identify the port in the switch/router that is under test from the remote.
BER Test
  • Able to perform 10/100/1000 Mbps framed layer 1(packet with preamble followed by PRBS data), and framed layer 2 (packet in 802.3 format) test.
  • PRBS data pattern supported are: 27?, 215?, 220?, 223?, 231?
Through Mode (GL-202/GL-220/GL-211)
  • These three models have 2 ports installed, use the versatile through-mode provided by the tester for advanced troubleshooting. This mode allows bandwidth usage to be analyzed with results and findings shown in the statistics view.
Trace Route Test
  • Able to perform trace route test to identify all MAC and IP address as well as its associated hostname in the route to the remote node.
Traffic Generation
With GiLaner user friendly interface, the tester can do the performance evaluation and statistics display through the full-wire rate packet generation function on the copper or optical port.
  • Support single or multi streams (Up to 8 streams) can be individually configured with traffic generation setup.
  • Able to configure FDX/HDX, preamble size, TX sequence tag, flow control and auto-negotiation.
  • Able to generate packet with variable data length ranging from 46 ~ 9000 bytes at up to 100% wire speed rate.
  • Generated packets can be varied with link speed( 10/100/1000 Mbps), duplex mode(full/half), TX packet number, or TX timer, or Non-Stop, packet length, data pattern, Source/ Destination MAC/IP address, VLAN ID and Priority, Double VLAN (QinQ), and TX utilization rate.
  • Able to generate error frames such as: oversize, undersize, dribble, alignment and FCS errors.
  • Able to do Constant / Burst transmission type.
  • Able to perform RFC2544 performance analysis which includes throughput test, frame loss rate test, back-to-back test & latency test.
  • Able to perform Internet work Throughput with two GiLaner (Up/Down stream test).
  • IPV4 packet generation with checksum at wired speed. The IP header is programmable by the user.
Statistics View
  • Various statistics counter of real time TX/RX PPS(Packets Per Second), TX/RX Utilization %, TX/RX Bandwidth, TX/RX Frames, VLAN, Pause Frame, Bit Error Count, Unicast, Multicast, Broadcast, Dribble, Alignment, Collision, Undersize, Oversize & FCS errors are all provided.
Reflector (optional)
  • Able to manually control for loop-back operation.
  • ARP supported, MAC/IP source/destination address, port number swapped automatically.
  • Able to loop-back all incoming traffic unchanged including invalid frames
Hardware Filter
  • MAC/IP source and destination address
  • ARP, Multicast or Broadcast
  • VLAN ID/Priority
  • Data Pattern for MPLS Tag, IP TOS, Cisco DSCP
Application 1: RFC2544 Benchmarking Tests
RFC2544 describes a set of procedures for measuring the performance of Ethernet equipments but it is also used for the overall network.
Procedures to measure performance are:
  • Throughput
  • Frame Loss
  • Back-To-Back
  • Latency
Other functions:
  • Traffic Generation
  • BER test
  • Bidirectional upstream/downstream test
  • Loopback mode
Application 2: Ping Trace-route/Flash Port
  • PING remote host to check network connectivity
  • Trace-route test to identify all the MAC/IP/Hostname in the route to the remote host.
  • Flash port to identify the remote port in the switch/router as a means to find out which port the cable is connected to from the remote.
Application 3: Link Status / Link Control
Connecting the cable to the remote RJ45 port or fiber port checks the network health. For RJ45 cable, it can also force the network link to the specified speed and mode to see the link capability of the remote link partner. The result will show:
  • Link: Up or Down
  • Duplex: Full or Half Duplex
  • Speed: Current Link mode (10 /100/1000 Mbps)
  • Quality: The signal strength for copper link (Good, Poor or Marginal)
  • Flow control: to see the flow control capability of current link
  • Auto-negotiation: to see the auto-negotiation capability of current link
