Some switches support automatic medium-dependent interface crossover
(MDIX). You can configure MDIX by using the mdix auto global configuration
switch command. If your switch supports MDIX, you do not need to follow these
cabling rules because MDIX automatically adjusts transmit and receive pairs
when an incorrect cable type (crossover or straight-through) is installed on a
10/100 Fast Ethernet port. However, when you configure MDIX, you must also
configure the port to use autosense (not manual selection of speed/duplex).
If you are connecting to Fast Ethernet ports on both the LAN and the WAN sides
Caution
of the WAVE inline appliance, you must consider the types of devices that are
being connected, and you must use the correct cables. You must follow these
cabling instructions for the inline network adapter to work properly. (See
Table
Cabling Examples for Fast Ethernet Connections" section on page
To connect the inline network adapter using the correct cables for Fast Ethernet
connections, follow these steps:
Step 1
Determine the type of cable that you would use for a direct connection between
your two end devices (without a WAVE inline network appliance connected
between them) by using the following standard cabling rules:

When you are directly connecting two network devices that are similar, such
as two switches, use a crossover cable.
When you are directly connecting two network devices that are different, such
as a switch and router, use a straight-through cable.
