Identifies the dynamic data service SAP. Only Ethernet ports and LAGs are
valid. The Dynamic Service SAP-ID uniquely identifies a Dynamic Data
Service instance. It can be specified explicitly or relative to the control
channel SAP-ID using wildcards. If explicitly specified, the Dynamic Data
Service SAP-ID and Control Channel SAP-ID do not have to be on the same
port.
The setup of the Dynamic Data Service fails if the SAP specified in Alc-Dyn-
Serv-SAP-Id is not created. The Dynamic Data Service SAP becomes
orphaned if the SAP is not deleted with a teardown action.
Parameters as input to the Dynamic Data Service Python script. The
parameters can cross an attribute boundary. The concatenation of all Alc-Dyn-
Serv-Script-Params attributes with the same tag in a single message must be
formatted as function-key <dictionary> where function-key specifies which
Python functions will be called and <dictionary> contains the actual
parameters in a Python dictionary structure format. In dynamic service
RADIUS accounting messages, the attribute is sent untagged and contains the
last received Alc-Dyn-Serv-Script-Params value in an Access-Accept or CoA
message for this dynamic service. Multiple attributes may be present if the
total length does not fit a single attribute.
The action specifies if a dynamic data service should be created (setup),
changed (modify) or deleted (teardown). Together with the <function-key> in
the Alc-Dyn-Serv-Script-Params, this attribute determines which Python
function will be called.The attribute is mandatory in a CoA message. The
attribute is optional in an Access-Accept message. If included in an Access-
Accept and the specified action is different from setup, the dynamic data
service action fails.
Specifies the local configured Dynamic Data Service Policy to use for
provisioning of this dynamic service. If the attribute is not present, the
dynamic services policy with the name default is used. If the default policy
does not exist, then the dynamic data service action fails.The Alc-Dyn-Serv-
Policy attribute is optional in case of modify or teardown actions; the policy
specified for the dynamic data service setup is automatically used. If the Alc-
Dyn-Serv-Policy is specified for modify or teardown actions, it must point to
the same dynamic services policy as used during the dynamic data service
setup. If a different policy is specified, the action fails.
