Multiple Child Sas And Dscp Marking Configuration - Cisco ASR 5000 Series Administration Manual

Femto Network Gateway Configuration
In the example above, the aaa aggregation interface type a12 command enables A12 aggregation for the
FNG service. The radius aggregation modify-nas-ip command specifies that the FNG modifies the NAS
IP address and port number to the local FNG bind address when forwarding A12 packets.
There are two aaa aggregation a12-destination-address commands in the example above. One
destination address is the IP address of the AN-AAA server, the other is the IP address of the FNG service. When the
FNG receives one of these destination addresses from a FAP, the FNG performs A12 aggregation.

Multiple Child SAs and DSCP Marking Configuration

It is recommended that multiple Child SAs are used on the FNG to provide the appropriate QoS services. This handling
can be applied to different types of traffic (voice and data) coming from the same UE behind a FAP, or from multiple
UEs belonging to the same QoS class. The FNG will determine the traffic type and provide a QoS treatment based on
configured rules.
Use the following configuration example to configure multiple Child SAs and DSCP marking:
configure
OL-24872-01
aaa aggregation a12-destination-address <ip_address_1>
aaa aggregation a12-destination-address <ip_address_2>
exit
context <fng_context_name>
class-map name <name> match-any
match dst-ip-address <ip_address>
exit
policy-map name <name>
class-map name <name>
qos encaps-header dscp-marking <0x2e>
child_sa_id <2>
exit
policy-group name <policygroup_out>
policy <name> precedence <number>
exit
subscriber default
policy-group <policygroup_out> direction <out>
exit
