Testing the Interface Numbering
This chapter describes the results of a test that was performed in order to
establish the numbering of the interfaces
eth0, eth1,
etc. on the various ap-
pliance models after one or two new six-port network interface cards had been
installed there.
4.1
Interface Numbering on the WW500
An additional network interface card with six ports on it, representing the model
mentioned above, was inserted in the free slot provided for this purpose.
Before installing the additional card, the two network interfaces on this appli-
ance were numbered as follows:
Onboard
interface 1
eth0
Onboard
interface 2
eth1
After installing the additional card, the interface numbering was:
Onboard
interface 1
eth6
Onboard
interface 2
eth7
Additional
card
eth5
eth4
eth3
eth2
eth1
eth0
