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 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. Interface contract Precedence An interface bandwidth contract is applied to downstream traffic before a user-role bandwidth contract is applied, and for 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 Example The following commands configure an interface as a trunk port for a set of VLANs: (host) (config) # interface fastethernet 1/2 (host) (config-range)# switchport mode trunk (host) (config-range)# switchport trunk native vlan 10 (host) (config-range)# switchport trunk allowed vlan 1,10,100 The following commands configure trunk port 1/2 with test-acl session for VLAN 2: (host) (config) # interface range fastethernet 1/2 (host) (config-range)# switchport mode trunk (host) (config-range)# ip access-group (host) (config-range) # ip access-group test session vlan 2 The following commands configure a interface bandwidth contract for a high-priority application: (host) (config) # interface gigabitethernet 1/1 (host) (config) # bw-contract protectskype4b exclude app alg-skype4b-voice downstream Related Commands (host) #show interface {fastethernet|gigabitethernet} // (host) #show datapath port vlan-table // 456| interface fastethernet | gigabitethernet Dell Networking W-Series ArubaOS 6.5.x | Reference Guide
