1. Use the information in the following table to set the WAN Frame Relay

Parameters:

Attribute Description

LMI Type Lets you set the type of local management protocol used on this link.

The link management type must be the same as the one used by the

frame relay service provider. The available options are Original LMI,

ANSI T1.617 Annex D or ITU-T Q.933 Annex A.

The default setting is Original LMI.

Polling Interval Lets you set an interval, in seconds, between LMI status inquiry

messages. The polling interval must be the same as the one used by the

frame relay service provider’s switch.

Possible values are between 5 and 30 seconds.

The default setting is 10.

Full Enquiry Interval Lets you set the maximum number of LMI Status Enquiry messages

sent before sending a Full Status Enquiry request. This value must

match the corresponding value set in the frame relay service provider’s

switch.

Possible values are between 1 and 255 (in seconds).

The default setting is 6.

Error Threshold Lets you set the maximum number of consecutive failures permitted in

LMI Status Enquiry before dropping the link. It is also the number of

successful consecutive LMI Status Enquiry messages that must be

received before marking a link as operational.

Possible values are between 0 and MAXINT.

The default value is 3.

Monitored Events Lets you set 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.

Possible values are a number between 0 and MAXINT.

The default value is 4.

DS Code Lets you set the Differentiated Services code (DSCode) recognized by

the frame relay driver for traffic prioritization. This value is a mask

value. When an IP packet is sent, the frame relay driver checks if the

packet's DSCode field (in the IP header) has any of the bits defined in

the DS Code.

Compression Enabled

PVCs

Lets you create a lists of PVCs on which data compression is enabled.

Type the list of PVCs for which data compression is enabled. The value

can be a comma-separated list of DLCI numbers.You can define a

range of DLCIs by inserting a hyphen between the lower and the upper

boundaries. A list can contain individual DLCI numbers and DLCI

ranges. If data compression is enabled, compression and decompression

operations are performed on the data going to and coming from the

PVCs enumerated on this list.

Access Rate Lets you set, in kbps, the maximum access rate on the interface running

frame relay. The frame relay congestion control engine uses this value

to limit or shape traffic. The Access Rate value is determined using the

T1 channels available for data communication on the port attached to

this interface and their data rates.
