AIS AI2524 Enable Frame Relay Traffic Shaping on the Interface, Frame-relay traffic-shaping

AI2524 Router Card User’s Manual

By defining separate virtual circuits for different types of traffic and specifying queuing and an outbound traffic rate for each virtual circuit, you can provide guaranteed bandwidth for each type of traffic. By specifying different traffic rates for different virtual circuits over the same line, you can perform virtual time division multiplexing. By throttling outbound traffic from high-speed lines in central offices to lower-speed lines in remote locations, you can ease congestion and data loss in the network; enhanced queuing also prevents congestion- caused data loss.

Traffic shaping applies to both PVCs and SVCs.

To configure Frame Relay traffic shaping, perform these tasks:

zEnable Frame Relay Traffic Shaping on the Interface

zSpecify a Traffic-Shaping Map Class for the Interfac

zDefine a Map Class with Queuing and Traffic Shaping Parameters

zDefine Access Lists

zDefine Priority Queue Lists for the Map Class

zDefine Custom Queue Lists for the Map Class

Enable Frame Relay Traffic Shaping on the Interface

In interface configuration mode, enable Frame Relay traffic shaping on an interface to enable both traffic shaping and per-virtual circuit queuing on all the interface's PVCs and SVCs:

frame-relay traffic-shaping

Specify a Traffic-Shaping Map Class for the Interface

If you specify a Frame Relay map class for a main interface, all the vir- tual circuits on its subinterfaces inherit all the traffic shaping parame ters defined for the class.

In interface configuration mode, specify a map class for the specified interface:

frame-relay class map-class-name

You can override the default for a specific DLCI on a specific sub- interface by using the class virtual circuit configuration command to assign the DLCI explicitly to a different class.
