9.6 Service Commands
The 'service' command set is used in DiffServ to define:
▫
Traffic Conditioning Assign a DiffServ traffic conditioning policy (as specified by the policy commands) to an interface in
the incoming direction
▫
Service Provisioning Assign a DiffServ service provisioning policy (as specified by the policy commands) to an interface
in the outgoing direction
The service commands attach a defined policy to a directional interface. Only one policy may be assigned at any one time to an
interface in a particular direction. The policy type (in, out) must match the interface direction to which it is attached.
This set of commands consists of service addition/removal.
The CLI command root is service-policy
9.6.1 service-policy
This command attaches a policy to an interface in a particular direction. The command can be used in the Interface Config
mode to attach a policy to a specific interface. Alternatively, the command can be used in the Global Config mode to attach this
policy to all system interfaces. The direction value is either in or out. The <policyname> parameter is the name of an existing
DiffServ policy, whose type must match the interface direction. Note that this command causes a service to create a reference
to the policy.
This command effectively enables DiffServ on an interface (in a particular direction). There is no separate interface
Note
:
administrative 'mode' command for DiffServ.
Note: This command shall fail if any attributes within the policy definition exceed the capabilities of the interface. Once a policy
is successfully attached to an interface, any attempt to change the policy definition such that it would result in a violation of said
interface capabilities shall cause the policy change attempt to fail.
