SELECTION DEFAULT OPTIONS DEFINITIONS
Card and Port
Administrative
State Unlocked Unlocked
Locked Enables or disables card/port for service,
respectively.
Congestion
Threshold 80 0-100 Percentage of ingress/egress buffer capacity that will
cause a congestion threshold notification.
Ring Selection Auto Auto
Ring 16
Ring 17
Card will automatically select traffic from the ring
direction with the best signal.
Card will receive traffic from Ring 16 direction.
Card will receive traffic from Ring 17 direction.
Low Ingress/Egress
Buffer Congestion
Onset/Abatement Variable This will cause the FECN/BECN in the frame relay
header to be set or cleared. Abatement is always ten
percent less than onset.
High
Ingress/Egress
Buffer Congestion
Onset/Abatement Variable Exceeding threshold causes frames with DE field
equal to 1 to be discarded. Frame discarding stops
upon reaching abatement level. Abatement is always
ten percent less than onset.
