Examples: Using the Ascend-Data-Filter Attribute for IPv6 Subscribers

This section provides examples showing the configuration of policies that use the Ascend-Data-Filter attribute when there are IPv6 subscribers in a network.

In this example, the following two Ascend-Data-Filter attributes are used to create RADIUS records that configure two policies. The first policy is an output policy that filters all UDP packets from network 2001:82ab:1020:87ec::0/64 to host 2001:82ab:1020:87ec:1234:0917:3415:0012, port 3090. The second policy is an input policy that filters all TCP packets that come from a port greater than 9000 on host 2001:82ab:1020:87ec:1234:0917:3415:0012 and that go to any destination.

Ascend-Data-Filter1 = "03000000 300182ab 102087ec 00000000 00000000 200182ab 102087ec 12340917 34150012 40801100 00000C12 00020000"

Ascend-Data-Filter2 = "03000100 200182ab 102087ec 12340917 34150012 00000000 00000000 00000000 00000000 80000600 23280000 03000000"

Table 8 lists the values specified in the Ascend-Data-Filter1 attribute that are used to create an output policy.
