and no tag is allowed in this path. However, packets with the ALL_VLAN tag are not filtered, so only packets from
the backbone can be transmitted over the downstream path.
12.2.7.4 User Profiles
The use of profiles allows securely assigning resources to end-user modems based on MAC address. They also
inform the master about the VLAN/OVLAN and QoS settings to be applied to the slave.
12.2.7.5 User Profiles inside auto-configuration
Inside a master’s auto-configuration file, there is a section with user profiles. These profiles contain the information
a master needs to know to configure a port to a new slave that enters the network. The information is related to QoS
and VLAN/OVLAN configuration.
The figure shows an example on the use of user profiles to configure different QoS settings:
User A
Profile 1
Configuration File
#Profile 1
BW = 500
#Profile 2
BW = 1000
Radius Server
M M
S S
User B
Profile 2
BW=500 BW=1000
Figure 163 Radius profiles example
There will be always an invited profile, profile number 1, applied to the users with no specific profile or if the
corresponding profile is not available. This invited profile, as well as the other profiles, can be redefined with autoconfiguration.
