Software Functional Description
Introduction
The Wide Area Application Engines (WAE-512 and WAE-612) support three different software installations that provide a comprehensive set of services for the remote office: Cisco Wide Area Application Services (WAAS) software, Cisco Wide Area File System (WAFS) software and Cisco Application and Content Networking System (ACNS) software.
The following software releases support the WAE-512 and WAE-612 appliances:
•
•
•
•
When WAAS software is installed, the WAE appliance can function as either a Central Manager or as an Application Acceleration Engine. When ACNS software is installed, the WAE appliance functions as a Content Engine or one of the other ACNS device modes (Content Router or Content Distribution Manager). When WAFS software is installed, the WAE appliance functions as a File Engine.
Figure 1-1 shows the WAE-512 and Figure 1-2 shows the WAE-612.
Figure 1-1 WAE-512—Front View
Figure 1-2 WAE-612—Front View
The WAE-512 and WAE-612 are configured for AC-input power and have a single AC-input power supply.
The WAE appliance has an integrated dual-port Ethernet controller, which supports 10BASE-T/100BASE-TX/1000BASE-TX Ethernet using RJ-45 receptacles. Both Ethernet ports support autodetect speed mode and full-duplex operation, which enable simultaneous transmission and reception of data on the Ethernet LAN.
WAE-512 and 612 models that are operating with ACNS software support an MPEG A/V decoder adapter. This adapter is user-replaceable and is installed in PCI-X slot 1 on the back panel.

Software Functional Description
The operation of the WAE is dependent on the software application that is installed on it. This section describes WAAS, ACNS and WAFS software:
WAAS Software Description
With WAAS software installed, the WAE appliance functions as either a WAAS Central Manager or a WAAS Application Acceleration Engine. The WAAS Central Manager provides a graphical user interface to monitor and configure all Acceleration Engines. The WAAS Acceleration Engine is deployed in remote branch offices and in the data center to accelerate TCP applications that access data across the network.
The Application Acceleration Engine functionality operates at different levels based on the software licenses purchased. WAAS 4.x, software offers the WAAS Transport License or the WAAS Enterprise License options.
Cisco WAAS software helps enterprises meet the following objectives:

ACNS Software Description
With ACNS software installed, the WAE appliance functions as a Content Distribution Manager, Content Engine, or Content Router. The Content Distribution Manager provides a graphical user interface to manage registered Content Engines and Content Routers. The ACNS solution addresses the need to distribute and receive high-bandwidth, media-rich content across the Internet or an intranet without performance losses or content-delivery delays.
ACNS software offers the following content-based services:
•
•
•
•
In Content Engine mode, the WAE operates either as a component of an ACNS network or as a standalone content-caching device and is generally positioned on the WAN edge between your enterprise network and the Internet.
Note
To deploy Cisco Content Engines with Cisco ACNS software within your existing network, your network must support Cisco IOS software and the Web Cache Communication Protocol (WCCP). WCCP transparently redirects HTTP requests to a Content Engine, and the Content Engine responds to those requests.
WAFS Software Description
With WAFS software installed, the WAE appliance functions as a File Engine. The File Engine is an Internet file delivery device that provides the following file-based services:

Inline Network Adapter Description
This section describes the following features of the WAE inline network adapter:
•
•
For adapter specifications, see Table A-4 in Appendix A.
Form and Function
Your appliance supports one optional 4-port Ethernet inline network adapter. The inline network adapter is a full-height, three-quarter-length PCI-X network interface card that contains four independent Gigabit Ethernet ports. (See Figure 1-11.)
Figure 1-11 Inline Network Adapter
The Cisco WAE inline network adapter provides inline traffic interception capability for your appliance. When your appliance is configured for inline interception mode, you can set attributes to control which interfaces are to be used over which VLANs. By default, the adapter operates on all inline-capable interfaces and VLANs. You can configure the inline redirection feature using the WAAS 4.0.7 CLI or the WAAS 4.0.7 Central Manager GUI.
The WAAS software defines two new interface types: A group interface that represents an inline pair grouping and a port interface that represents the individual port. These interfaces are referred to as inlineGroup and inlinePort, respectively.
InlineGroup interfaces are numbered using the format slot/group. The slot number is the slot in which the adapter is inserted. (In the WAE 500 series and 600 series appliances, the adapter must be installed in slot 1 only.) The group number is either 0 or 1 (each adapter has 2 group pairs). The group number is displayed on the adapter label.
InlinePort interfaces are numbered slot/group/lan or slot/group/wan. The last attribute is the LAN or WAN designator.
The inline network adapter also includes an onboard programmable Watch Dog Timer (WDT) controller. You can set the time to wait after a failure event, such as a power outage or a kernel crash, before the unit begins to operate in mechanical bypass mode. In mechanical bypass mode, traffic is bridged between the LAN and WAN ports of each group. Mechanical bypass mode prevents the WAE from becoming a single point of failure and allows traffic to continue to flow between the router and the client while it passes through an unresponsive WAE without being processed.
For more information about configuring the inline network adapter, see the Cisco Wide Area Application Services Configuration Guide.
Ports and LED Indicators
Figure 1-12 shows the inline network adapter port numbers, interface designations, and LEDs. Table 1-7 describes the LED functions.
Figure 1-12 Inline Network Adapter Port Numbering and LEDs
Port 0; Group 1 WAN interface
Port 1; Group 1 LAN interface
Port 2; Group 0 WAN interface
Port 3: Group 0 LAN interface
The inline network adapter has three LEDs that correspond to each port (the 0 LEDs correspond to Port 0, and so forth). Table 1-7 describes the LEDs.
Inline Network Adapter Cabling Requirements
Your inline network adapter ships with two types of cables: crossover and straight-through. When you connect the WAE inline network adapter, proper cabling depends on the link speed (Gigabit Ethernet or Fast Ethernet) and the types of devices (DCE or DTE) being connected.
Note
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.
Table 1-8 shows the cable requirements for WAE and non-WAE connections when you are using Gigabit Ethernet end to end.
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).
Caution
To connect the inline network adapter using the correct cables for Fast Ethernet connections, follow these steps:
Step 1
•
•
Note
Table 1-9 shows the cable requirements for WAE and non-WAE connections when you are using Fast Ethernet end to end.
Step 2
•
•
For example, if you are connecting a router and a switch (two different devices) through the WAE inline appliance, use a straight-through cable on the LAN side of the connection and use a crossover cable on the WAN side of the connection. (If you were connecting the two different devices directly, you would use a straight-through cable, so use the crossover cable instead.)
If you are connecting two switches (or two similar devices), use straight-through cables on both the LAN and the WAN sides of the WAE inline appliance.
Figure 1-13 through Figure 1-15 show the cables to use for the WAE LAN and WAN connections between Fast Ethernet ports.
Installation Scenarios and Cabling Examples for Fast Ethernet Connections
WAE appliances can be installed physically between two network devices (such as the branch office router and branch office LAN switch) by connecting the WAE inline network adapter ports to the network devices using the proper cables.
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). 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, the other WAE can provide optimization. (See Figure 1-14.)
