Informational Note:  This feature is  supported on the following platforms:

F9272-X

F9232-C

F9372-T

AS5512-54X

AS6712-32X

S6010-ON

Z9100-ON

Control Plane Traffic Protection (CPTP) refers to a new feature that allows the user to impose rate limits on the flow of traffic that arrives on the CPU management port. When control plane traffic arrives out-of-band on the management NIC of the switch, there is currently no such protection. There is the possibility that excessive control plane traffic may saturate the 1G management port or starve the CPU of other critical traffic.

Syntax   cpu-mgmt-class-modify

name arp|icmp|ssh|snmp|fabric|
bcast|nfs|web|web-ssl|net-api

Select the class of traffic to modify.

one or more of the following options:

rate-limit unlimited

Specify the ingress rate limit on the management port in Bps or unlimited.

burst-size default

Specify the ingress traffic burst size in bytes or default.

Defaults   Disabled by default.

Access   Network Administrator

History   Command introduced in Version 3.0.0.

Usage   Use this command to modify management services to the CPU configuration.

Examples  To modify the rate limit for ARP traffic to 100 Bps,  use the following syntax:

CLI network-admin@switch > cpu-mgmt-class-modify name arp rate-limit 100 Bps

cpu-mgmt-class-show

Syntax   cpu-mgmt-class-show

name arp|icmp|ssh|snmp|fabric|bcast|nfs|web|web-ssl|net-api

Displays the class of traffic.

one or more of the following options:

rate-limit unlimited

Displays the ingress rate limit on the management port in Bps or unlimited.

burst-size default

Displays the ingress traffic burst size in bytes or default.

Formatting Options

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.

sort-asc

Display output in ascending order.

sort-desc

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.

show-headers|
no-show-headers

Display column headers or not.

limit-output number

Limit the display output to a specific number of entries.

count-output

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

unscaled

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

raw-int-values

Display integer values instead of mapped values

sum-by

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

History   Command introduced in Version 3.0.0.

Usage   Use this command to display information about CPU traffic management.

Examples  To display information about CPU management, use the following syntax:

CLI network-admin@switch > cpu-mgmt-class-show

switch  name    rate-limit
