BCM 4.0 Networking Configuration Guide

To add PVC congestion control

1 Click Configuration > Resources > Network Interfaces.

2 Click the WA N 1 or WA N 2 heading.

The WAN Summary panel appears.

3 Click the PVC Configuration tab.

The PVC Configuration panel appears.

4 Click Add.

5 The Add PVC Configuration dialog box appears. See Figure 159.

6 Configure the WAN PVC parameters. Refer to the information in Table 15.

7 Click OK.

Data compression

retry time

<1-15> Enter the interval to wait before restart handshake procedure

by the Mode 1-DCPCP in case the remote end fails to

respond.

Default: 3 seconds

End to end

fragmentation

<check box> Select to Enable End-to-End Fragmentation on this PVC.

Default: Disabled

Fragmentation size <200-800> Maximum frame size in bytes. Any packets that have a frame

size larger than this value will be fragmented.

Default: 256

Congestion control <check box> Parameter used for enabling Congestion Control per PVC.

Default: Disabled

CIR (kbps) <0-1024> Enter the committed information rate in kbits. The CIR is the

data rate, the carrier commits to the user, that the router

transmits at over a predetermined time interval when

congestion is not present.

Contact your service provider for the correct setting.

BCM uses one-second intervals to measure this parameter.

Default: 64

Committed burst

(kbits)

<read-only> Maximum amount of data the carrier guarantees to transport

over the network, under normal conditions, during the Tc

measurement interval. Calculate this value with the formula:

BC=CIRxTc (Tc=1/4 in BCM implementation).

EIR (kbps) <read-only> Excess Information Rate is determined by the excess burst

divided by Tc. EIR=Be/Tc.

Excess burst (kbits) <0-1024> Excess burst (Be) is the maximum amount of data by which

the user may exceed the committed burst during a Tc

measurement interval. The combined value of committed burst

and excess burst must be less than, or equal to, the line

speed.

Default: 16

Broadcast <check box> When broadcast is enabled, broadcast packets are sent out

over this PVC.
