Chapter 1 Introducing the Cisco Wide Area Application Engine
Hardware Features
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. This section
shows cabling examples for Fast Ethernet connections only, because Fast Ethernet
has specific cabling requirements.
The inline network adapter has four ports that are divided into two inline groups
(see the
“Ports and LED Indicators” section on page 1-16
). The WAE can be
physically placed inline between two distinct network paths, creating redundant
WAN links. (See
Figure 1-13
.)
Two WAEs with inline network adapters can also be installed back-to-back in a
serial fashion between two network devices for failover purposes. In this type of
serial cluster configuration, if one WAE fails or becomes overloaded, the other
WAE can provide optimization. (See
Figure 1-14
.)
Note
When you connect two WAE inline appliances to each other in serial fashion,
always use a crossover cable between the two WAEs. (See
Figure 1-15
.)
