It certainly appears to be working and up in promic mode...

eth4      Link encap:Ethernet  HWaddr 00:1b:21:33:55:20
          inet6 addr: fe80::21b:21ff:fe33:5520/64 Scope:Link
          RX packets:474826801 errors:0 dropped:0 overruns:0 frame:0
          TX packets:6 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:330011101828 (330.0 GB)  TX bytes:468 (468.0 B)

Thanks all, I will continue to dig...

The simplest cause could be that you have an issue with the tap/span port that is supposed to be feeding you traffic.  Is your sensor definitely receiving traffic?  Are the ethernet links up?
