Precedence Order in Policy Maps
A policy map can be attached to one or more interfaces to specify a service policy. Configuration sources
combined with context determines which QoS policy map is applied. The three configuration sources
and their general order of precedence are as follows:
1. Per-user (per-subscriber) configuration
2. Service profile
3. Interface configuration
This order of precedence shows the general condition, that is, service profiles and per-user
configurations have higher priority than interface configurations.
However, a change of authorization (CoA) per-user push replaces the current per-user configuration for
any overlapping or common feature. Similarly, when a new service logs in, its configuration replaces any
overlapping feature, from previously configured service profiles, that is not already in effect from a
per-user configuration source
If the new service then logs off, the previously existing configuration is reapplied if no
higher-precedence configuration source is in effect.
Given those precedence qualifications, the policy map is determined as follows:
• If there is no policy map on the session, the incoming policy map is not applied.
• If an existing policy map is configured from a higher priority source than an incoming one, the
incoming policy map is not applied.
• If an existing policy map is configured from a lower priority source than an incoming one, the
incoming policy map replaces it.

• Configuring ISG QoS to IP Sessions, page 4
See the section “Configuring Per-Session QoS Using the ISG Framework” in the “Configuring ISG
Control Policies” chapter in Cisco IOS XE Intelligent Services Gateway Configuration Guide for
information about configuring a local service profile.
