One thing you can quickly do is to use NBAR protocol discovery. Configure the 'ip nbar protocol-discovery' command under the appropriate interface. Then, issue the 'show ip nbar protocol-discovery' command which will show you bit-rates per protocol. It does not tell you which station is sourcing the traffic but does help you to isolate it at least to the application.
To get stats per station, I would enable 'ip accounting' on your interface. Then you can use 'show ip acounting' in conjuntion with 'clear ip accounting' to see where the traffic is coming from.
Two things i would like to add in addition to the other netpros suggestion.
1.Do check the bandwidth command configured under the interface where you are seeing TX ratio.
If the link connected is of high B/W capacity and you got to have the default bandwidth command set under the interface you may end up getting errorneous ratio.
2.You can also enable netflow in your router on the ethernet interface to check the geninuity of the traffic flow .
The commands ip route-cache flow configured under the interface mode will be able to provide the flow details,you can view those flow details using show ip cache flow command.The O/P will be give you the clear details of the source and destination ip address,port numbers used by the traffic flow.
if you find something fishy you can alwasy track down the source ip based on the port no thru which it transacts and bring it down which can also help to bring the network traffic to normal..
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
