Testing the Interface Numbering

Interface Numbering on the WW1900
On this model of the Webwasher appliance, two network interface cards are
already installed in slots at the rear side when the appliance is shipped.
You may either replace and upgrade one of these cards or both.
Replacing One Network Interface Card
Before installing the new card, the four network interfaces on this appliance
were numbered in the following way:
Two additional
cards
eth0
eth1
Onboard inter-
faces 1 + 2
eth3 eth2
The new card was first used to replace the additional network interface card in
the left slot.
The interface numbering was then as follows:
Left additional
card new
eth0 eth1 eth2 eth3 eth4 eth5
eth6
Onboard inter-
faces 1 + 2
eth8 eth7
Then the new card was used to replace the additional network interface card
in the right slot.
This led to the following interface numbering:
Right addition-
al card new
eth6
eth0 eth1 eth2 eth3 eth4 eth5
Onboard inter-
faces 1 + 2
eth8 eth7
