Advanced
(small active text on the right, just below line 'Size')Allows 'Advanced configuration' - more parameters
appear.
Accounted bytes
(appears only if 'Advanced configuration' is activated)This parameter determines which frame bytes
are to be accounted for in the rate resource's rate limiting calculations. There are four different
supported configurations:
• Frame — Frame based configures the rate limiting resource to account for the number of frames
from a given port mapped to this rate resource.
• layer 1 — Preamble (8bytes) + Frame’s DA to CRC + IFG (inter frame gap, 12 bytes)
• layer 2 — Frame’s DA to CRC
• layer 3 — Frame’s DA to CRC - 18 - 4 (if the frame is tagged)
A frame is considered tagged if it is either Customer of Provider tagged during ingress.
Bucket increment
(appears only if 'Advanced configuration' is activated)Bucket increment (BI) indicates the amount
of tokens that need to be added for each byte of the incoming frame.
Rate factor
(appears only if 'Advanced configuration' is activated)This is a bucket factor (green or yellow) which
determines the amount of tokens that need to be decremented for each rate resource decrement
(which is done periodically based on the
Committed Information Rate
).
Limit CBS/EBS
(appears only if 'Advanced configuration' is activated)Excess Burst Size limit - used for the yellow
bucket. Committed Burst Size limit - used for the green bucket.
Color mode
(appears only if 'Advanced configuration' is activated)Indication of the current color mode. Possible
values: Single rate two color, Single rate three color, Dual rate three color.
Account green overflow
false = Green and Yellow buckets are isolated when in Color Aware modetrue = Green and Yellow
buckets are connected when in Color Aware mode
Account discarded frames
This parameter decides whether the ingress rate limiting logic accounts for frames that have been
discarded by the queue controller due to output port queue congestion reasons. To account for all
frames coming into a given port associated with this rate resource, this parameter needs to be set.
Account filtered frames
This parameter decides whether the ingress rate limiting logic accounts for frames that have been
discarded because of ingress policy violations. To account for all frames coming into a given port
associated with this rate resource, this parameter needs to be set.
Color aware
false = color blind mode
true = color aware mode
EBS limit action
This parameter controls what kind of action is performed when the
EBS limit
has been exceeded.
Two types of action can be selected:
• drop — The frame that was received on the port will get discarded.
