The advantage of dynamic compression is a higher compression ratio. However, dynamic compression is
slower than static compression, as it requires two passes to complete the process.
l No Compression
You can use no compression for data such as an embedded image file that might already be in a
compressed format. Such data does not compress well, and may even increase in size.
For details on configuring this feature using the Smart Config WebUI, see WAN Configuration on page 317.
Interface Bandwidth Contracts
W-7000 Seriescontrollers have the ability to classify and identify applications on the network. If a W-7000
Seriescontroller is configured as a branch office controller, you can create bandwidth contracts to limit traffic
for individual applications (or categories of applications) either sent from or received by a selected interface.
There are two basic models for using this feature.
l Limiting lower-priority traffic: If there is a lower-priority application or application type that you want to
limit, apply a bandwidth contract just to that application, and allow all other application traffic to pass
without any limits.
l Protecting higher-priority traffic: If you want to guarantee bandwidth for a company-critical application
or application group, you can add that application to an exception list, then apply a bandwidth contract to
all remaining traffic.
You can apply bandwidth contracts using one or both of these models. Each interface supports up to 64
bandwidth contracts. An interface bandwidth contract is applied to downstream traffic before a user-role
bandwidth contract is applied, and upstream traffic, the user-role bandwidth contract is applied before the
interface bandwidth contract.
For all traffic using compression and encryption, bandwidth contracts are applied after that traffic is
compressed and encrypted. If you apply more than one bandwidth contract to any specific category type, then
the bandwidth contracts are applied in the following order.
1. A contract that explicitly excludes an application
2. A contract that explicitly excludes an application category
3. A contract that applies to a specific application
4. A contract that applies to a specific application category
5. A generic bandwidth contract, not specific to any application or application category

Integration with a Palo Alto Networks (PAN) Portal
Dell controller deployments can leverage their networks' existing PaloAlto infrastructure to access more
advanced security services, including antivirus services, malware detection and seamless integration with the
Palo Alto Networks WildFire
TM
cloud-based threat detection.
Enable Palo Alto firewall integration on a master controller to securely redirect internet inbound traffic from
branch controllers using the branch config group into the PAN firewall. Although this configuration setting can
be used on standalone or local controllers, this feature can only be used on controllers in these types of
deployments when used in conjunction with the controller uplink VLAN manager feature.
