Cisco BPX 8600 Series Installation and Configuration

Release 9.3.30, Part Number 78-12907-01 Rev. E0, May 2005

Chapter 21 Configuring ATM Connections

Traffic Policing Examples

Variable Bit Rate Dual-Leaky Bucket Policing Examples

The contract for a variable bit rate (VBR) connection is set up based on an agreed upon sustained cell
rate (SCR) with allowance for occasional data bursts at a Peak Cell Rate (PCR) as specified by maximum
burst size (MBS).

When a connection is added, a VPI.VCI address is assigned, and UPC parameters are configured for the
connection. For each cell in an ATM stream, the VPI.VCI addresses are verified and each cell is checked
for compliance with the UPC parameters as shown in Figure 21-21.

The VBR cells are not enqueued, but are processed by the policing function and then sent to the network
unless discarded.

For VBR, traffic policing, depending on selected policing option, are based on the following:

•

Leaky bucket 1, PCR and CDVT

•

Leaky bucket 2, SCR, CDVT, and MBS

The policing options for VBR connections, selected by entering 1 to 5 in response to the policing choice
prompt, are shown in Table 21-15.

Table 21-15 Policing Options for VBR Connections

Option

Description

VBR.1

VBR with
policing set to 1.

CLP(0+1) cells compliant with leaky bucket 1 are passed to leaky bucket 2;
noncompliant cells are discarded. CLP(0+1) cells compliant with leaky bucket
2 are admitted to the network; noncompliant cells are discarded.

VBR.2

VBR with
policing set to 2.

CLP(1) cells compliant with leaky bucket 1 are admitted to the network;
noncompliant CLP(0+1) cells are dropped. CLP(0) cells compliant with leaky
bucket 1 are applied to leaky bucket 2; noncompliant cells are dropped. CLP(0)
cells compliant with leaky bucket 2 are admitted to the network; noncompliant
cells are dropped.

VBR.3

VBR with
policing set to 3.

CLP(1) cells compliant with leaky bucket 1 are admitted to the network;
noncompliant CLP(0+1) cells are dropped. CLP(0) cells compliant with leaky
bucket 1 are applied to leaky bucket 2; noncompliant cells are dropped. CLP(0)
cells compliant with leaky bucket 2 are admitted to the network; noncompliant
cells are tagged and admitted to the network.

VBR with
policing set to 4.

CLP(0+1) cells compliant with leaky bucket 1 are admitted to the network;
noncompliant cells are dropped. Leaky bucket 2 is not active.

VBR with
policing set to 5.

Policing is off, so there is no policing of cells on ingress.
