Attaching 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:
The router does not support QoS service policies on ATM point-to-multipoint subinterfaces. However,
Note
you can apply service policies to VCs that are configured on multipoint interfaces.
Command
Step 1
Router(config)# interface atm
slot/module/port
Step 2
Router(config-if)# atm pxf queuing
Step 3
Router(config-if)# interface atm
slot/module/port.subinterface
point-to-point
Step 4
Router(config-subif)# service-policy
{input | output} policy-map-name
OL-7433-09
Purpose
Specifies the ATM interface and enters interface configuration
mode.
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.
This is the required interface operating mode for
Note
QoS service policies that include queuing actions.
Specifies the point-to-point subinterface and enters subinterface
configuration mode.
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.
For QoS policies containing the bandwidth, priority,
Note
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.
