Field Name

Description

 

 

 

 

Discovery

The method used for determining the address of

 

the LES. Possible methods are:

 

Auto - The address of the LES is discovered

 

 

using the proprietary ’automatic LES address

 

 

determination method’.

 

Manual - The LES’s address is manually

 

 

entered.

 

 

Early Packet Discard

There are two packet discard thresholds for each

Threshold

option card, called Early Packet Discard (EPD) and

 

Partial Packet Discard (PPD). By default, both

 

thresholds have a default set limit and are enabled.

 

The Cajun M770 ATM Device uses EPD to discard

 

entire AAL5 frames for ABR and UBR traffic (rather

 

than random cells from different frames), when it

 

determines that it is about to become congested.

 

The Cajun M770 ATM Device passes through the

 

last cell of each AAL5 frame so that end stations are

 

aware that a discard has taken place. You can

 

configure a threshold at which the EPD will be

 

invoked. The threshold is a percentage of the

 

overall shared buffer space.

 

 

ELAN Name

ELAN Type
