To create a policy, you use hexadecimal format to configure the Ascend-Data-Filter
attribute on the RADIUS server. For example:
Ascend-Data-Filter="01000100 0A020100 00000000 18000000 00000000 00000000"
Ta b l e 6 lists the fields in the order in which they are specified in the hexadecimal
Ascend-Data-Filter attribute.
NOTE: An E-series router dynamically assigns names to the new classifier list and
policy list based on information such as the interface and direction of the policy.
