You can modify bandwidth guarantees on switch ports. Currently, Pluribus Networks switches allow rate limiting only for CPU facing (PCIe, data and span) ports. Using this feature, you can configure bandwidth guarantees at egress CoS (Class of Service) queue level and manage prioritized traffic. The feature is also used for setting SLAs (Service Level Agreements).

Syntax   port-cos-bw-show


cos integer

Specify the CoS priority between 0 and 7.

port port-list

Specify the physical port(s).

min-bw-guarantee min-bw-guarantee-string

Specify the minimum bandwidth as a percentage.

max-bw-limit max-bw-limit-string

Specify the maximum bandwidth as a percentage.

weight priority 

Specify the scheduling weight after the bandwidth guarantee is met.

Formatting Options

(show commands only)

format fields-to-display

Display output using a specific parameter. Use all to display all possible output.

parsable-delim character

Display output formatted for machine parsing using a specified delimiter.


Display output in ascending order.


Display output in descending order.

show dups

Display duplicate entries in the output.

layout vertical|horizontal

Format the output in a vertical or horizontal layout.

show-interval seconds-interval

Repeat the show command at a specified interval.


Display column headers or not.

limit-output number

Limit the display output to a specific number of entries.


Display the number of entries in the output. This is useful with vRouter show commands.


Display full values in the output instead of scaled approximate values.


Display integer values instead of mapped values


Aggregate output by specific parameters. If sum-by fields are specified, records that have the same value in sum-by fields are combined and displayed as one aggregate record. NOTE: This option is only available for show commands that collect statistics such as connection-stats-show.

Defaults   None

Access   Network Administrator


Version 2.6.0

Command introduced.

Version 3.0.0

The parameter, weight, added.

Usage   Use this command to display CoS bandwidth information for a port or range of ports.

Examples  To display the CoS bandwidth, use the following syntax:

CLI (network-admin@Spine1) > port-cos-bw-show


switch      cos port  min-bw-guarantee max-bw-limit weight

----------- --- ----- ---------------- ------------ ------

Spine1      0   1-104 0%               100%         16     

Spine1      1   1-104 0%               100%         32     

Spine1      2   1-104 0%               100%         32     

Spine1      3   1-104 0%               100%         32     

Spine1      4   1-104 0%               100%         32     

Spine1      5   1-104 0%               100%         32     

Spine1      6   1-104 0%               100%         64     

Spine1      7   1-104 0%               100%         127
