BCM 4.0 Networking Configuration Guide

PVC Configuration

If frame relay is your link protocol, you must configure PVC. If PPP is your link protocol, there

are no PVC Congestion Control settings to configure.

Monitored events <0-65000> Enter the number of events sampled for making decisions about

the error threshold. This value must be set to a higher number

than the value set in the Error Threshold box.

Default: 4

DS code (0-255) <0-255> Enter the Differentiated Services code recognized by the frame

relay driver for traffic prioritization. When an IP packet is sent, the

frame relay driver checks if the packet's ToS field (in the IP

header) matches with the value defined in the DS Code. If the

values match, then the packet is not treated as Discard Eligible

(DE) packet during congestion.

Default: 184

Available PVC <read-only>

Lists the PVCs (Permanent Virtual Circuits) available for this WAN

interface.

Access rate (kbps) <read-only> The available bandwidth on the interface running Frame Relay.

The value is determined based on the number of channels

selected in the WAN T1 Parameters tab and the channel rate

value for T1 interfaces. If the interface type is Synchronous, the

Access Rate value is determined based on the Clock Rate

attribute for DCE interfaces or based on the Configured

Linkspeed for DTE interfaces located under Configuration >

Data Services > QoS Queuing.

Status enquiry message

wait interval

<1-100> Select the interval to wait for the arrival of the status enquiry

message.

Default: 15 seconds

Inverse ARP Enable

Disable

Disabled - the remote end IP address and DLCI mapping has to

be provisioned.

Enabled - the remote end IP address and DLCI mapping is

discovered.

Default: Enable

Fragmentation status Disable

End to End

fragmentation

Controls the Frame Relay end-to-end fragmentation on the

interface.

Note: Enable the end-to-end fragmentation at PVC level to

fragment the frames sent over the PVC.

Default: End to End fragmentation

Low water mark

(packets)

<1-14> Lower threshold that controls the link layer queuing behavior.

Default: 6

High water mark

(packets)

<2-15> Upper threshold that controls the link layer queuing behavior.

Default: 7
