Step a
To apply the specified limits and actions to the downlink (data to the subscriber):
configure
context <
context_name
>
subscriber name <
user_name
>
qos rate-limit downlink
end
Step b
To apply the specified limits and actions to the uplink (data to the subscriber):
configure
context <
context_name
>
apn <
apn_name
>
qos rate-limit uplink
end
Step 2
Optional
. Configure the maximum number of PDP contexts that can be facilitated by the APN to limit the APN’s
bandwidth consumption by entering the following command in the configuration:
configure
context <
context_name
>
apn <
apn_name
>
max-contexts primary <
number
> total <
total_number
>
end
Notes:
There are numerous keyword options associated with
qos rate-limit direction { downlink | uplink
}
command.
For more information on commands, refer
Command Line Interface Reference
If the exceed/violate action is set to
lower-ip-precedence
, this command may override the configuration of
the
ip qos-dscp
command in the GGSN service configuration mode for packets from the GGSN to the
SGSN. In addition, the GGSN service
ip qos-dscp
command configuration can override the APN setting for
packets from the GGSN to the Internet. Therefore, it is recommended that command not be used in conjunction
with this action.
Repeat as needed to configure additional Qos Traffic Policing profiles.
Note that, if a “subscribed” traffic class is received, the system changes the class to background and sets the
following:
The uplink and downlink guaranteed data rates are set to 0.
If the received uplink or downlink data rates are 0 and traffic policing is disabled, the default of 64 kbps
is used. When enabled, the APN configured values are used.
