IxExplorer Operation – Operating Modes.
Operating Modes
IxExplorer 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.

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. ***

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.

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.

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.

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.

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 the
resource tree.
Delete, copy, paste and duplicate
streams. Like Excel, multiple streams
can be selected simultaneously by
using the Ctl and shift keys.

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 properties
window.

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 configure
stream rate and duration.
Warnings display any illegal
or incorrectly formed
packets. This tab is red
when an active warning is
present..

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 be
fixed, random,
increment or Auto.
DA / SA MAC.
Protocols tab allows you to set layer 3 – 4
properties.

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
Edit button to edit
IP parameters.
Layer 2

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 TCP
opens the TCP
header window.
Here you can set the TCP / UDP
port numbers, sequence
number and all relevant flags.

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.
Stream
Termination

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.

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 Overview
Statistic 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 Statistic Overview
Through 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.

Receive Mode.
The intended receive port must be configured for latency measurements in
the receive mode configuration window.
Select the port receive mode
then check packet groups.
Assign off-set and packet
group signature to fit the
expected TX packet.
The apply to all port saves
configuring multiple times.

Transmit Mode.
Create a packet capable of traversing the network / device under test.
Check Time Stamp and
Packet Group Signature
then click Edit
Unless there is a special
requirement check the Use
PGID config, Use Stream
Number and Apply to all
streams checkboxes.

The 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
Stream statistics allow you to view the frame count and rate transmitted from
a port on a per stream basis.
