Attaching Frame Relay QoS Service Policies
map-class frame-relay Command History
Usage Guidelines for the map-class frame-relay Command
You can attach a QoS service policy to a Frame Relay map class using the service-policy command. For
more information, see the
“service-policy Command” section on page 4-3.
You can apply a map class to a Frame Relay interface and subinterface.
Restrictions and Limitations for Frame Relay QoS Service Policies
• Do not configure Frame Relay services using both the modular QoS command-line interface (MQC)
and the Frame Relay legacy commands.
• For Cisco IOS Release 12.0(22)S and later releases, use the MQC to configure QoS services for
Frame Relay interfaces.
• For all releases earlier than Cisco IOS Release 12.0(22)S, use the Frame Relay commands to
configure Frame Relay QoS services. For more information, see
Appendix A, “Configuring Frame
Relay QoS Using Frame Relay Legacy Commands.”
• The router has no preset scaling limit for Frame Relay QoS services. You can apply any number of
Frame Relay QoS services.
• The router does not support attaching QoS service policies to Frame Relay point-to-multipoint
subinterfaces.
• You cannot attach a policy map and a map class to the same subinterface. For Cisco IOS
Release
12.0(22)S and later releases, use the MQC to create and attach a policy map as described in
this chapter. For all releases earlier than Cisco IOS Release 12.0(22)S, use the Frame Relay legacy
commands to create and attach a Frame Relay QoS policy as described in
Appendix A, “Configuring
Frame Relay QoS Using Frame Relay Legacy Commands.”
• Output QoS policies that contain queuing actions must be nested service policies.
