Chapter 1 Using the WAAS Command-Line Interface
Using Command Modes
Device Mode
The WAAS software provides the ability to specify the device mode of a WAAS device. In a WAAS
network, you must deploy a WAAS device in one of the following device modes:
• Central Manager mode—Mode that the WAAS Central Manager device needs to use.
• Application accelerator mode—Mode for a WAAS Accelerator (that is a Core WAE or Edge WAE)
that is running the WAAS software. WAEs are used to optimize TCP traffic over your network.
When client and server applications attempt to communicate with each other, the network intercepts
and redirects this traffic to the WAEs so that they can act on behalf of the client application and the
destination server. The WAEs examine the traffic and use built-in application policies to determine
whether to optimize the traffic or allow it to pass through your network unoptimized.
The default device mode for a WAAS device is application accelerator mode. The device mode global
configuration command allows you to change the device mode of a WAAS device.
waas-cm(config)# device mode ?
application-accelerator Configure device to function as a WAAS Engine.
central-manager Configure device to function as a WAAS Central Manager.
For example, after you use the WAAS CLI to specify the basic network parameters for the designated
WAAS Central Manager (the WAAS device named waas-cm) and assign it as a primary interface, you
can use the device mode configuration command to specify its device mode as central-manager.
waas-cm# configure
waas-cm(config)#
waas-cm(config)# primary-interface gigabitEthernet 1/0
waas-cm(config)# device mode central-manager
waas-cm(config)# exit
waas-cm# copy run start
waas-cm# reload
Proceed with reload?[confirm] y
Shutting down all services, will Reload requested by CLI@ttyS0.
Restarting system.
To display the current mode that the WAAS device is operating in, enter the show device-mode current
EXEC command:
WAE# show device-mode current
Current device mode: application-accelerator
To display the configured device mode that has not taken effect, enter the show device-mode configured
EXEC command. For example, if you had entered the device mode central-manager global
configuration command on a WAAS device to change its device mode to central manager but have not
entered the copy run start EXEC command to save the running configuration on the device, then if you
were to enter the show device-mode configured command on the WAAS device, the command output
would indicate that the configured device mode is central-manager:
WAE# show device-mode configured
Configured device mode: central-manager
Because WAAS Central Manager must be deployed on a dedicated appliance, a WAAS device can
operate only in one device mode: either in central-manager mode or application-accelerator mode.
The set of WAAS CLI commands that are available vary based on the device mode of the WAAS device.
