Jessie,
A few things. I'm not sure why a capture card for Ethereal would want to
"bypass main CPU processing". The only way that Ethereal works is for
the main CPU to do the work. Any ethernet card that libpcap works with
should do - I am not sure why a special request would be required.
Also unless you are doing something very curious an Ethernet card is not
going to support OC-3 or OC-12. These are SONET specs which are only
relevant if you are doing ATM or Packet over SONET or the link. The
Ethernet fibre specs you should be interested in are 10BaseFL,
100BaseFX, 1000BaseSX/LX etc. (And again most NICs today only support
one media - you are possibly better off either with a media converter or
alternatively just expect your fibre-based ethernet switches to support
port spanning/mirroring to a copper port/

Can you direct me to someone that know were I can purchase an Network
Sniffer Interface Card with the below spec's?
Jessie,
We are looking for a network sniffer interface card that handles
grabbing Ethernet frames and placing them in computer memory for
Application processing. The goal of the card is to off-load main CPU
processing and bypass IP stack processing by simply capturing ethernet
frames. The card need not be in-line with the traffic, nor does it need
to be able to transmit, but these are bonuses. It is for a highspeed
passive network sniffer application. The card vendor should supply an
Application Programming Interface (API) that allows us to write
applications in C/C++ to process the sniffed frames. The card should
timestamp each frame as it arrives and provide an indicator that the
card has overflowed should traffic increase beyond its ability to
process. The card should meet the following specifications:
Interfaces:
Minimum Requirement: Ethernet Copper RJ45 10/100/1000BaseT ,
Fiber interface is a plus
Desired Interfaces: OC-3, OC-12
PC Compatibility
PCI/PCI-X interface
Linux Redhat Release 3 drivers.
That should be a start. Anything that comes close, we would want to at
least look at.
