priority
To assign priority to a class of traffic belonging to a policy map, use the priority command in policy-map
class configuration mode. To remove a previously specified priority for a class, use the no form of this
command.
priority [ Kbps [ burst -in-bytes ] | level level-value [ Kbps [ burst -in-bytes ] ] | percent percentage [ Kb/s [ burst
-in-bytes ] ] ]
no priority [ Kb/s [ burst -in-bytes ] | level level value [ Kb/s [ burst -in-bytes ] ] | percent percentage [ Kb/s
[ burst -in-bytes ] ] ]
Syntax Description
(Optional) Guaranteed allowed bandwidth, in kilobits per second
(kbps), for the priority traffic. The amount of guaranteed bandwidth
varies according to the interface and platform in use. Beyond the
guaranteed bandwidth, the priority traffic will be dropped in the event
of congestion to ensure that the nonpriority traffic is not starved. The
value must be between 1 and 2,000,000 kbps. Kb/s
(Optional) Burst size in bytes. The burst size configures the network
to accommodate temporary bursts of traffic. The default burst value,
which is computed as 200 milliseconds of traffic at the configured
bandwidth rate, is used when the burst argument is not specified.
The range of the burst is from 32 to 2000000 bytes. burst -in-bytes
(Optional) Assigns priority level. Available values for level-value
are 1 and 2. Level 1 is a higher priority than Level 2. Level 1 reserves
bandwidth and goes first, so latency is very low.
level level-value
(Optional) Specifies the amount of guaranteed bandwidth to be
specified by the percent of available bandwidth. percent percentage
Command Default
No priority is set.
