Summary:
How are ports paired for internal bypass functionality on IDP 50, 200, 600, 1100?
Symptoms:
bypass IDP 50, 200, 600, 1100
Solution:
The new IDP appliances with internal bypass on copper ports are set up to have bypass ports in the following matching pair:
 
  eth2 <==> eth3
  eth4 <==> eth5
  eth6 <==> eth7
  eth8 <==> eth9
eth10 <==> eth11
 
For the built-in copper ports, each NIC has two ports defined above.
To use internal bypass functionality, you also have to hook up to the ports like above.
 
If the box dies, traffic comes in at eth2 will be sent out at eth3 and vice versa, for example.
