— Specifies the DiffServ policy name as a unique case-
sensitive alphanumeric string. (Range: 1–31 alphanumeric characters)
Default Configuration
This command has no default configuration.
Command Mode
Global Configuration mode (for all system interfaces)
Interface Configuration (Ethernet, Port-channel) mode (for a specific
interface)
User Guidelines
This command effectively enables DiffServ on an interface. No separate
interface administrative mode command for DiffServ is available.
Ensure that no attributes within the policy definition exceed the capabilities
of the interface. When a policy is attached to an interface successfully, any
attempt to change the policy definition, such that it would result in a
violation of the interface capabilities, causes the policy change attempt to
fail.
Example
The following example shows how to attach a service policy named "DELL" to
all interfaces.
console(config)#service-policy DELL
