Configuring a WAAS policy
To configure a WAAS policy, perform the following tasks:
1.
Create a WAAS policy.
2.
Use a WAAS class in the WAAS policy.
3.
Configure actions for the WAAS class.
4.
Enable optimization features.
You can configure the following actions for a WAAS class:
•
Optimization
actions
—Optimize matching TCP traffic and include TFO, DRE, and LZ
compression. TFO is required. DRE and LZ compression are optional.
•
Passthrough
action
—Allows matching TCP traffic to pass through unoptimized.
To configure a WAAS policy:

2.
Create a WAAS policy and
enter WAAS policy view.
waas policy
policy-name
By default, only the predefined
WAAS policy exists.
As a best practice, configure a
WAAS policy by modifying the
predefined WAAS policy.
3.
Specify a WAAS class and
enter WAAS policy class

Configure optimization
actions or the passthrough
action.

6.
Enable DRE.
waas tfo optimize dre
By default, DRE is enabled.
7.
Enable LZ compression.
waas tfo optimize lz
By default, LZ compression is
enabled.
Applying a WAAS policy to an interface
Apply a WAAS policy to the interface that connects to the WAN. The device optimizes or passes
through the traffic entering and leaving the WAN according to the configured policy. If traffic enters
and leaves the device on interfaces that are both connected to the WAN, the traffic is not optimized.
A WAAS policy can be applied to multiple interfaces. Only one WAAS policy can be applied to an
interface.
