IxExplorer Operation


12/65

IxExplorer Operation – Operating Modes.

Operating ModesIxExplorer can be operated locally (On chassis desktop) or remotely via

client software.

On opening IxExplorer you will be prompted to enter the I.P address of the

chassis.

• For local operation acceptable addresses are: ***

– 127.0.0.1

– The Chassis IP address or

– The word: “loopback”

• For Remote operation you must enter the Chassis IP address only.


13/65

IxExplorer Operation – The Interface.

The Interface

The 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 with

each others tests. ***


14/65

IxExplorer Operation – Resource Tree.

Windows Area: Resource Tree

The resource tree is a tree view of available Chassis, cards and ports

available. ***

The tree view displays ownership of ports in brackets.

If port is already owned by another user the settings to adjust the packet

streams will be grayed out. ***

Ports 1,2 & 3 are owned by user 1,2 & 3 so the packet

streams are grayed out for configuration.


15/65

IxExplorer Operation – Port Ownership.

Windows Area: Resource Tree

When you select an un-owned port the packet streams are free for

configuration.

Ports 4 has no current ownership and can be configured.


16/65

IxExplorer Operation – Port Ownership.

User Management

You can select the user management pop-up through Multi-user > User

Management.

Ownership can also be taken and released by right clicking the level

required in the resource tree.


17/65

IxExplorer Operation – Generating Packet Streams.

Packet Streams

By default each port is configured with a single packet stream.

This is displayed by clicking on Packet Streams under the required port.


18/65


Packet Streams

Streams are added as line items much like in an excel spread sheet. Right

clicking a stream gives you the ability to copy, paste, duplicate or insert a

new stream with default values.

Streams can be copied across ports, cards and chassis within theresource tree.

Delete, copy, paste and duplicate

streams. Like Excel, multiple streams

can be selected simul taneously by

using the Ctl and shif t keys.


19/65


Packet Streams

Double clicking an individual packet stream brings up the stream properties

window, allowing you to configure the packet properties.

Double click the packet stream to

bring up the stream propertieswindow.


20/65

IxExplorer Operation – Configuring Packet Streams.

Stream Property Window

The stream property window has four main tabs. They are Frame Data,

Stream Control, Packet View and Warnings. ***

Frame Data to configure

frame size, payload and

MAC address.

Packet View breaks the

packet into it ’s OSI layer

properties and displays in

both clear text and

Hexidecimal.

Stream Control to conf igure

stream rate and duration.

Warnings display any illegal

or incorrectly formed

packets. This tab is red

when an active warning is

present..


21/65


Packet Streams: Frame Data Tab

The frame data tab allows you to set the frame size, payload, preamble

size, 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 – 4

properties.


22/65


Packet Streams: Frame Data Tab / Protocols

The protocols tab allows you to set the layer 2 – 4 properties. It also adds

Cisco ISL, VLAN’s and MPLS tags as required.

Ether Type Layer 3 Layer 4

IP parameters.

Layer 2


23/65


Packet Streams: Frame Data Tab / Protocols / Edit IP

The IP header allows you to set poriority (TOS QoS), Ip Dest and Source

address, packet fragmentation and TTL. ***

Clicking Edit TCPopens the TCP

header window.

Here you can set the TCP / UDP

port numbers, sequence

number and all relevant flags.


24/65


Packet Streams: Stream Control

Through the stream control tab you can adjust the data rate by % of line

rate, packets/sec or bit rate. You also select how you want the stream to

terminate.

Rate Control .

Termination


25/65


Packet Streams: Stream Control

The available stream termination controls are continuous packet,

continuous burst, stop after this stream, advance to next stream return to

ID and return to ID for count.


26/65

IxExplorer Operation – Transmitting Streams.

Transmitting Streams

Once streams have been configured, you have inspected the packet view

for 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 on

this port will be transmitted.

Select desired option from Transmit Bar.

Statistic Views.

Statistic OverviewStatistic views allows you to see the received data on a port.

Statistics are closely tied to capture filters and receive modes of the port.

Statistics are available as total count and rate per second.

Statistics can be viewed and graphed per packet stream.Statistics can be used to generate logging and alerts.

Statistics can include filters for:

• TOS/QOS.

• Frame size.• IP / MAC DA/SA.

• User defended filters set to a byte off-set.

Statistics can be:

• Graphed

• Combined with simple formulas i.e. Tx port 1 – Rx Port 2.

• Used to determine latency and packet sequence.

Packet Group Statistic Views.

Packet Group Statist ic OverviewThrough the Packet Group Statistic View function, Ixia provide a means of

measuring latency / sequence on a per Stream basis.

The per stream measurement allows the user to identify latency and packet

sequencing with different frame sizes, TOS/QOS, TCP port numbers and

protocols.

A maximum of 65,000 streams can be monitored individually on any

receiving port.

Operates through inserting a time stamp and Packet Group ID (PGID) at

user defined off-set.Latency, like statistics views can be graphed or saved into a Excel spread

sheet.

LATENCY MUST BE SET UP TO SEND AND RECEIVE TIME STAMPS FROM

THE SAME OFF-SET IN BOTH TRANSMIT AND RECEIVE MODES.

Port GroupsThe Ixia chassis allows you to group ports.

This allows you to perform functions across a group of ports instead of

individually.

These functions include:

• Run, Stop and Step Through packet streams,

• Group capture,

• Group port ownership functions:

– Take ownership

– Clear ownership

Stream Statistics
