Inline Network Adapter Cabling Requirements
You must retain the same link speed from one end of the connection to the other
Note
end. Inline adapter interfaces are able to autonegotiate link speeds. If you
configure any of your connecting interfaces for Fast Ethernet (whether on a switch
or a router), your WAE inline adapter uses Fast Ethernet. If you configure any of
your connecting interfaces for Gigabit Ethernet, your WAE inline adapter uses
Gigabit Ethernet. Speed and duplex settings are port specific so that two inline
ports can negotiate different speeds independently.
If you are connecting a WAE inline appliance between two devices using Gigabit
Ethernet, you can use either straight-through cables, crossover cables, or any
combination of the two cable types, regardless of the type of device. However, for
consistency, we recommend that you use straight-through cables for all Gigabit
Ethernet connections.

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
