# atm vp-tunnel

#### Syntax

atm vp-tunnel vpi { cbr kbps | kbps }

no atm vp-tunnel vpi

#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

Defines a virtual path tunnel and configures the rate of traffic flow within the tunnel. For QoS configurations, use to configure a shapeless VP tunnel. The no version removes the restriction.

#### Options

- vpi—Number in the range 0–255; virtual path identifier of this PVC
- cbr—Specifies the service class as constant bit rate
- kbps—Tunnel rate for a virtual path. The tunnel rate can be a value in the range 0–4294967295, when you specify the rate of traffic flow without the constant bit rate (CBR) service category, and can be a value in the range 1–4294967295, when you specify the rate of traffic flow with the CBR service class. Because the CBR service category guarantees a fixed amount of bandwidth to be allotted to the client, an error message is displayed if you configure a value of 0 for the tunnel rate for CBR traffic flows. The aggregate to this traffic from all circuits configured in the tunnel is held to the specified rate. Certain line modules may have minimum rates for VP tunnels. Using a rate of 0 configures a shapeless tunnel (a tunnel with no rate) that is used for VP shaping in the SAR.
