Chapter 4 Attaching Service Policies
Attaching ATM QoS Service Policies
Attaching QoS Service Policies to an ATM Point-to-Point Subinterface
To attach a QoS service policy to an ATM point-to-point subinterface, enter the following commands
beginning in interface configuration mode:
Note The router does not support QoS service policies on ATM point-to-multipoint subinterfaces. However,
you can apply service policies to VCs that are configured on multipoint interfaces.
Command Purpose
Step 1
Router(config)# interface atm
slot/module/port
Specifies the ATM interface and enters interface configuration
mode.
Step 2
Router(config-if)# atm pxf queuing
Specifies the interface mode. In this mode, the interface operates
in low VC count. The router operates in atm pxf queuing mode by
default. You do not need to specify this mode unless the router is
currently configured for no atm pxf queuing.
Note This is the required interface operating mode for
QoS
service policies that include queuing actions.
Step 3
Router(config-if)# interface atm
slot/module/port.subinterface
point-to-point
Specifies the point-to-point subinterface and enters subinterface
configuration mode.
Step 4
Router(config-subif)# service-policy
{input | output} policy-map-name
Attaches the service policy you specify to the ATM subinterface.
input indicates to apply the service policy to inbound traffic on
the interface.
output indicates to apply the service policy to outbound traffic on
the interface.
Note For QoS policies containing the bandwidth, priority,
random-detect, queue-limit, and shape commands, you
must specify the output keyword. If you use these
commands with the input keyword, the router ignores the
commands.
policy-map-name is the name of the policy map you want to attach
to the subinterface.
Note The router applies the service policy to the
ATM
subinterface and to all PVCs configured on the
subinterface that does not have its own QoS policy
applied.
