Early Packet Discard
Threshold
There are two packet discard thresholds for each
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 The name of the ELAN.
ELAN Type The type of ELAN. Possible types are:
•
