The committed action, which specifies the action for packets conforming to the
committed rate and committed burst size and conforming to the exceed rate and
exceed burst size for a rate-limit profile is set to receive transmit unconditional.
The conformed action, which sets the action for packets not conforming to the
committed rate and committed burst size, but conforming to the peak rate and peak
burst size for a rate-limit profile is set to receive transmit unconditional.
Two external parent groups, one each for the ingress and egress interfaces, that reference
the rate-limit profiles created for incoming and outgoing traffic, are created and specified
in the service definition.
Classifier control lists for ingress IPv4 and IPv6 traffic, and for egress IPv4 and IPv6 traffic,
are also created. These classifiers classify traffic based on source and destination
addresses.
The input and output classifier lists for IPv4 traffic are used in IP policy lists that are
attached to the ingress and egress IPv4 interfaces respectively. The input and output
classifier lists for IPv6 traffic are used in IPv6 policy lists that are attached to the ingress
and egress IPv6 interfaces respectively. The external parent-group keyword creates an
external parent group in a rate-limit hierarchy for IPv4 and IPv6. All packets matching
the classifier are sent to the parent group for further processing.
The policy lists for voice-over-IP traffic are configured in the service definition macro file
that creates a combined IPv4/IPv6 service to be applied to the ingress IPv4 and IPv6
interfaces.
A profile is created that you want to attach to the service session. The IPv4 and IPv6
policies for voice-over-IP traffic arriving at the IPv4 and IPv6 interfaces respectively are
applied to the secondary input stage. The IPv4 and IPv6 policies for voice-over-IP traffic
leaving the IPv4 and IPv6 interfaces respectively are applied to the output stage. Statistics
collection is enabled for the policies referenced in the service macro using the statistics
enabled keyword in the command used for policy attachment in the profile. The merge
keyword enables merging of multiple policies to form a single policy.
The <# env.setResult("activate-profile", profileName) #> command specifies the
interface profile to be used on activation of the interface. After the subscriber service
session is activated, the policies defined in the interface profile are applied to both IPv4
and IPv6 interfaces. The elements in the profile to be attached to the interfaces are
determined by the type of the interface.
The <# env.setResult("service-interface-type", "ipv4-ipv6") #> command configures
the service macro to be used for IPv4 and IPv6 interfaces in a dual stack. The profile
identifier returned from the activate-profile object will be applied to both IPv4 and IPv6
interfaces.
The service definition macro is configured to collect input and output statistics associated
with external parent groups in a hierarchical policy for IPv4 and IPv6 subscribers as
follows:
<# env.setResult("secondary-input-stat-epg", "vb-v4v6-"$ uid $"-in v4v6-"$ uid $"") #>
<# env.setResult("output-stat-epg", "vb-v4v6-"$ uid $"-out v4v6-"$ uid $"") #>
