What is the configuration of Omnipliance Core and how many different configurations are available?

Ominplaince Core is available in 2 TB, 6 TB, or 8 TB of storage.

What is the extent of 802.11n support in Omni 5.1?

Capturing of 802.11n packets
Fully decode all 802.11n specific information elements in packets.
Provide 802.11n-specific statistics, analyses and expert diagnoses.

What adapters do you support for 802.11n captures?

At the present time, we support the Buffalo Nfiniti, Model # WLI-CB-AG300N and the Netgear WN511T using the Marvell driver that is supplied with Omni 5.1 and can be found at:

http://www.wildpackets.com/support/downloads/drivers.

When I configure a capture with my Buffalo card, it reports a speed of 1Mbps instead of 54Mbps in the Capture Options. Why?

This is because Omni 5.1 is reporting the actual speed of the adapter’s connection, not its maximum data rate.

Why are the 40 MHz 802.11n channels missing from the Expert Network Policy screen?

These channels have been added to the Network Policy screen of OmniPeek 5.1.

Since all WildPackets products make use of the underlying Operating System for all time computations, no patch will be necessary for our products to operate correctly with the new Daylight Saving Time Change.

To start the Omnipliance:
Press the Power button on the front of the Omnipliance. After the Omnipliance has finished loading, the LCD displays will display the WildPackets Omnipliance welcome screen.

To shutdown the Omnipliance:
You can shutdown the Omnipliance from the OS or the LCD controls. *Do not* shutdown the Omnipliance by pressing the power button.

To shut down the Omnipliance through the LCD controls:

1. Make sure there are no remote desktop sessions active and that there are no users logged into the Omnipliance.
2. From the welcome screen press the Cancel button twice to display the option to initiate a system shutdown.
3. Press the check button to shutdown.

The Omnipliance administrator password is in the manual. We recommend changing the administrator password on your first login AND adding additional Windows users/passwords to the Omnipliance.

Before configuring the ports on the Omnipliance, make sure an Ethernet cable is connected from at least one of the Gigabit Ethernet ports to your network!

1. If a DHCP server is accessible, you can configure the Omnipliance using the server’s default network settings. Please read the Omnipliance documentation on how to view the default settings for a network with a DHCP server.
2. You can manually configure the IP network settings in the Omnipliance by using the arrow buttons on the front of the Omnipliance. NOTE: You should choose View Settings. Set Settings will set the Omnipliance. Please see the Omnipliance documentation for further instructions.

IP Address 1st Gigabit Ethernet Port (Left): 172.16.1.2
IP Address 2nd Gigabit Ethernet Port (Right): 172.16.1.3
Subnet Mask (Both): 255.255.0.0
Gateway (Both): 172.16.1.1
DNS (Both): 172.16.1.1

Please notify WildPackets first before breaking the seal, this activity will be logged and used as reference if the Omnipliance should require any future warranty support.

Yes, the Omnipliance can be added to your Corporate Domain.

OmniEngine Linux

• Operating System upgrade to Red Hat Enterprise Linux 5.1
• Voice and Video over IP Media and Signaling Analyses
• Voice and Video over IP Reporting
• Application Analyses and APDEX Support
• RADIUS and TACACS+ Support
• Expert Enhancements
• Performance Improvements
• Ability to control NetOptics switch

The Linux-based Omnipliance can be managed and configured with the OmniEngine Manager.

The OmniEngine Manager is included with both OmniPeek and OmniEngine. It provides an interface for connecting to, configuring and updating remote OmniEngines. Please see the OEM Readme or Help file if you need more details on the OmniEngine Manager.

OmniEngine Linux now supports ACL, Radius and TACACS+

You must select "Third Party" Authentication to connect to Linux-based Omnipliance. Selecting "Default" Authentication causes this error.

In the Capture/Monitor Options, select Performance. For peak performance, right click on one of the features and choose Disable All. This way, the Linux-based Omnipliance will capture at peak performance, and analysis features can later be applied to a saved capture. During capture, if you need a particular feature, you can always enable it. As you enable/disable individual features, the performance bar at the bottom of the Performance Options dialog will move to show you an estimate of the impact of each feature.

Here are a few more tips to improve the performance of the Linux-based Omnipliance:

• Disable the Monitor adapter (Monitor/Select Monitor Adapter/None)
• Turn off scroll during capture. Control + K will start/stop scroll.
• Disable passive name resolution. Under Tools/Options/Name Resolution, uncheck enable passive name resolution.
• Turn off any automatic report production for monitor and/or capture. Under Monitor or Capture options, select Statistics Output. Uncheck Save statistics report.



The following component is an additional module (not included in the standard package):


• Disable RMONGrabber (Tools/Options/Analysis Modules)

If you need one of the other features, you can enable it when you are actually viewing the capture file. Also if you're on a switched network, you can try using the switch's mirroring or monitoring capability to zero-in on the traffic you're looking for. Try only mirroring ports one by one to avoid overloading the analyzer with traffic.

Yes, multiple simultaneous captures are supported.

The OmniAdapters do not send packets as they are designed for capture only.

Currently, only our Windows-based Omnipliance supports wireless captures.

Currently, only our Windows-based Omnipliance supports WAN captures.
