  11. 11. IxExplorer Operation
  12. 12. IxExplorer Operation – Operating Modes.Operating ModesIxExplorer can be operated locally (On chassis desktop) or remotely viaclient software.On opening IxExplorer you will be prompted to enter the I.P address of thechassis.• For local operation acceptable addresses are: ***–– The Chassis IP address or– The word: “loopback”• For Remote operation you must enter the Chassis IP address only.
  13. 13. IxExplorer Operation – The Interface.The InterfaceThe interface consists of a Title Bar, Menus, Tool Bar, Transmit Bar,Windows Area, Status Window and Status Bar.Port Ownership allows multiple users to coincide without interfering witheach others tests. ***
  14. 14. IxExplorer Operation – Resource Tree.Windows Area: Resource TreeThe resource tree is a tree view of available Chassis, cards and portsavailable. ***The tree view displays ownership of ports in brackets.If port is already owned by another user the settings to adjust the packetstreams will be grayed out. ***Ports 1,2 & 3 are owned by user 1,2 & 3 so the packetstreams are grayed out for configuration.
  15. 15. IxExplorer Operation – Port Ownership.Windows Area: Resource TreeWhen you select an un-owned port the packet streams are free forconfiguration.Ports 4 has no current ownership and can be configured.
  16. 16. IxExplorer Operation – Port Ownership.User ManagementYou can select the user management pop-up through Multi-user > UserManagement.Ownership can also be taken and released by right clicking the levelrequired in the resource tree.
  17. 17. IxExplorer Operation – Generating Packet Streams.Packet StreamsBy default each port is configured with a single packet stream.This is displayed by clicking on Packet Streams under the required port.
  18. 18. IxExplorer Operation – Generating Packet Streams.Packet StreamsStreams are added as line items much like in an excel spread sheet. Rightclicking a stream gives you the ability to copy, paste, duplicate or insert anew stream with default values.Streams can be copied across ports, cards and chassis within theresource tree.Delete, copy, paste and duplicatestreams. Like Excel, multiple streamscan be selected simultaneously byusing the Ctl and shift keys.
  19. 19. IxExplorer Operation – Generating Packet Streams.Packet StreamsDouble clicking an individual packet stream brings up the stream propertieswindow, allowing you to configure the packet properties.Double click the packet stream tobring up the stream propertieswindow.
  20. 20. IxExplorer Operation – Configuring Packet Streams.Stream Property WindowThe stream property window has four main tabs. They are Frame Data,Stream Control, Packet View and Warnings. ***Frame Data to configureframe size, payload andMAC address.Packet View breaks thepacket into it’s OSI layerproperties and displays inboth clear text andHexidecimal.Stream Control to configurestream rate and duration.Warnings display any illegalor incorrectly formedpackets. This tab is redwhen an active warning ispresent..
  21. 21. IxExplorer Operation – Configuring Packet Streams.Packet Streams: Frame Data TabThe frame data tab allows you to set the frame size, payload, preamblesize, MAC address and to insert time and sequence stamps.Payload can be fixed,increment, decrement,random or custom.Frame size can befixed, random,increment or Auto.DA / SA MAC.Protocols tab allows you to set layer 3 – 4properties.
  22. 22. IxExplorer Operation – Configuring Packet Streams.Packet Streams: Frame Data Tab / ProtocolsThe protocols tab allows you to set the layer 2 – 4 properties. It also addsCisco ISL, VLAN’s and MPLS tags as required.Ether Type Layer 3 Layer 4Edit button to editIP parameters.Layer 2
  23. 23. IxExplorer Operation – Configuring Packet Streams.Packet Streams: Frame Data Tab / Protocols / Edit IPThe IP header allows you to set poriority (TOS QoS), Ip Dest and Sourceaddress, packet fragmentation and TTL. ***Clicking Edit TCPopens the TCPheader window.Here you can set the TCP / UDPport numbers, sequencenumber and all relevant flags.
  24. 24. IxExplorer Operation – Configuring Packet Streams.Packet Streams: Stream ControlThrough the stream control tab you can adjust the data rate by % of linerate, packets/sec or bit rate. You also select how you want the stream toterminate.Rate Control.StreamTermination
  25. 25. IxExplorer Operation – Configuring Packet Streams.Packet Streams: Stream ControlThe available stream termination controls are continuous packet,continuous burst, stop after this stream, advance to next stream return toID and return to ID for count.
  26. 26. IxExplorer Operation – Transmitting Streams.Transmitting StreamsOnce streams have been configured, you have inspected the packet viewfor errors and the warning are clear you are able to start transmitting. ***To run the packet streams select the level you would like to run from• Selecting a chassis will run all streams attached to the chassis.• Selecting a card will run all streams attached to the card.• Selecting a port will only run streams attached to that port.Port 1 of Card 2 Selected. Only streams onthis port will be transmitted.Select desired option from Transmit Bar.
