Traffic Shaping for PPP over ATM Interfaces

The router supports the configuration of traffic shaping parameters for PPP over ATM (PPPoA) via domain-based profiles and RADIUS. In connection with this feature, Table 8 describes VSAs that apply to dynamic IP interfaces and are supported on a per-user basis from RADIUS.

Table 8: Traffic-Shaping VSAs That Apply to Dynamic IP Interfaces

VSA	Description	Type	Length	Subtype	Subtype Length	Value
Service-Category	Specifies the type of service	26	12	14	6	integer: 1 – UBR 2 – UBR PCR 3 – NRT VBR 4 – CBR 5 – RT VBR
PCR	Specifies the value for the peak cell rate (PCR)	26	12	15	6	integer
SCR	Specifies the value for the sustained cell rate (SCR)	26	12	16	6	integer
MBS	Specifies the maximum burst size (MBS)	26	12	17	6	integer

To configure traffic-shaping parameters for PPPoA via domain maps, use the atm command in Domain Map Configuration mode.

atm

Use to configure traffic-shaping parameters for PPPoA.
Use one of the following keywords to select the traffic category to configure:
- ubr—Unspecified bit rate
- ubrpcr—Unspecified bit rate with peak cell rate
- nrtvbr—Non–real time variable bit rate
- rtvbr—Real time variable bit rate
- cbr—Constant bit rate
