burst-limit
Syntax burst-limit {default | size [byte | kilobyte]}
no burst-limit
Context config>port>ethernet>access>egr>qgrp>qover>q
config>port>ethernet>access>ing>qgrp>qover>q
config>port>ethernet>network>egr>qover>q
Description The
queue burst-limit command is used to define an explicit shaping burst size for a queue. The con-
figured size defines the shaping leaky bucket threshold level that indicates the maximum burst over the
queue’s shaping rate.
The
burst-limit command is supported under the sap-ingress and sap-egress QoS policy queues. The
command is also supported under the ingress and egress queue-group-templates queues.
The no form of this command is used to restore the default burst limit to the specified queue. This is equiva-
lent to specifying burst-limit default within the QoS policies or queue group templates. When specified
within a queue-override queue context, any current burst limit override for the queue will be removed and
the queue’s burst limit will be controlled by its defining policy or template.
Parameters default — The default parameter is mutually exclusive to specifying an explicit size value. When burst-
limit default is executed, the queue is returned to the system default value.
size — When a numeric value is specified (size), the system interprets the value as an explicit burst limit
size. The value is expressed as an integer and by default is interpreted as the burst limit in Kilobytes. If
the value is intended to be interpreted in bytes, the byte qualifier must be added following size.
Values 1 to 14,000 (14,000 or 14,000,000 depending on bytes or kilobytes)
Default No default for size, use the default keyword to specify default burst limit
byte — The bytes qualifier is used to specify that the value given for size must be interpreted as the burst
limit in bytes. The byte qualifier is optional and mutually exclusive with the kilobytes qualifier.
kilobyte — The kilobyte qualifier is used to specify that the value given for size must be interpreted as the
burst limit in Kilobytes. The kilobyte qualifier is optional and mutually exclusive with the bytes quali-
fier. If neither bytes nor kilobytes is specified, the default qualifier is kilobytes.
cbs
Syntax cbs size-in-kbytes
no cbs
Context config>port>ethernet>access>egr>qgrp>qover>q
config>port>ethernet>access>ing>qgrp>qover>q
config>port>ethernet>network>egr>qover>q
Description The cbs command is used to define the default committed buffer size for the template queue. Overall, the cbs
command follows the same behavior and provisioning characteristics as the cbs command in the queue-
group or network QoS policy. The exception is the addition of the cbs-value qualifier keywords bytes or
kilobytes.
