How do I access the new CDR (Call Detail Records)?

In the Capture Options Statictics Output, enable the "Save statistics report". Then under the "Report type" select the Call Detail Records option.

Does the Omnipliance support 10 Gig networks?

Yes, Omnipliance does support 10 Gigabit capture and analysis. Please visit http://www.wildpackets.com/products/analysis_cards/ 10GbE for more information.

How can I optimize my Omnipliance to get the best performance possible?

How can I sync my Omnipliance Linux to an NTP server?

Please refer to the Omnipliance Getting Started Guide that was included with your machine.

How do you set the Omnipliance time zone configuration for the computer’s physical location.

Please refer to the Omnipliance Getting Started Guide that was included with your machine.

My Statistics Output reports are not being output to the correct destination. Why?

When doing Statistics Output, setting the output interval too low may cause some reports to not be output when intended. If reports are not being output at the desired time, you may wish to increase the output interval.

Can I change my adapter buffer size?

Adapter buffer size in the Adapters view does not apply to the OmniEngine Linux. The default buffer size for all installed adapters is set to '0'.

Can I make changes to OmniAdapter in the Omnipliance?

Making changes to WildPackets Gigabit analyzer cards is not recommended unless using OmniPeek or the OmniEngine Manager.

Why am I receiving bad checksum messages on some outgoing packets?

This problem may be caused by the network card's ability to offload the calculation of IP, TCP, and/or UDP checksums from the TCP/IP protocol stack. If the OmniEngine Linux is sending the packets, the checksums may appear incorrect if the hardware is calculating the checksums. A work around is to disable this feature on the network card. The following command will turn off the feature for the specified adapter in the OmniEngine Linux computer:

ethtool -K eth# tx off (where # is the adapter index)

Note: The adapter must be in a 'down' state for the change to take effect. The change will not persist across a reboot.

Some of my outgoing packets are unusually large. Why?

This problem may be caused by the network card's ability to offload TCP/IP protocol stack. If the OmniEngine Linux is sending the TCP packets, some of these packets may be unusually large if the hardware is doing the segmentation. A work around is to disable this feature on the network card. The following command will turn off the feature for the specified adapter in the OmniEngine Linux computer:

ethtool -K eth# tso off (where # is the adapter index)

Note: The adapter must be in a 'down' state for the change to take effect. The change will not persist across a reboot.

Can I change the VoIP region settings?

Yes, you can edit the omni.conf file (/etc/omni) to change the VoIP region. The omni.conf file lists the possible values. Restart the OmniEngine Service for the changes to take effect.

How do I turn the Omnipliance On and Off?
