Applying QoS Parameters Dynamically to Sessions
Configuring the Router for Dynamic QoS Policies at the Session Level
To configure the router for dynamic QoS policies at the session level, enter the following commands
beginning in global configuration mode:
Configuration Example for Configuring the Router for Dynamic QoS Policies at the Session Level
Example 17-14 shows how to configure the router for dynamic QoS policies at the session level. In the
example, dynamic bandwidth selection is enabled on PVC 1/101 on the ATM subinterface 4/0/0.1.
Example 17-14 Configuring the Router for Dynamic QoS Policies at the Session Level
Router(config)# interface atm 4/0/0.1
Router(config-subif)# pvc 1/101
Router(config-if-atm-vc)# dbs enable
Router(config-if-atm-vc)# encapsulation aal5mux ppp Virtual-Template 1
Command Purpose
Step 1
Router(config)# interface atm
slot/module/port.subinterface
point-to-point
Specifies the ATM subinterface. Enters subinterface
configuration mode.
Step 2
Router(config-subif)# pvc [name] vpi/vci
Specifies an ATM PVC and enters ATM VC configuration mode.
(Optional) name is the name of the PVC. The name can have up
to 16 characters.
vpi/ is the ATM network virtual path identifier (VPI) for the PVC.
Valid values are from 0 to 255. If you do not specify a vpi value,
the vpi value defaults to 0. If the vci value is 0, you cannot set the
vpi value to 0. The slash character is required.
vci is the ATM network virtual channel identifier (VCI) for the
PVC. Valid values are from 1 to 65535. Typically, the lower
values 0 to 31 are reserved for specific traffic and you should not
use these. If the vpi value is 0, you cannot set the vci value to 0.
Note The VCI is a 16-bit field in the header of the ATM cell and
because the value has local significance only, it is unique
only on a single link, not throughout the ATM network.
Step 3
Router(config-if-atm-vc)# dbs enable
Enables dynamic bandwidth selection and allows the traffic
shaping parameters retrieved from RADIUS to be applied to the
PVC.
Step 4
Router(config-if-atm-vc)# exit
Exits ATM VC configuration mode.
Step 5
Router(config-subif)# exit
Exits subinterface configuration mode.
Step 6
Router(config)# policy-map
policy-map-name
Configures or modifies a policy map. Enters policy-map
configuration mode.
policy-map-name is the name of the policy map.
