cluster-bringup-show

This feature provides configurable parameters for controlling the activation of VLAG ports in a cluster to ensure sub-second failover. Sub-second traffic loss is required for failover events in a cluster configuration with active-active VLAGs. Netvisor can wait a measurable time to move L2 entries from one port to another during failover and failover recovery port up and down events. This contributes to traffic loss during these events. To ensure traffic loss events remains sub-second, it is required to manage the activation of VLAG ports on the node recovering from the failover.

Syntax   cluster-bringup-show

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   CLI

History   

Version 2.5

Command introduced.

Version 2.5.4

Command renamed to cluster-bringup-modify.

Version 3.0.0

The parameter, state, has two new options:

cluster-link-up-wait — waiting for cluster links to come up

min-delay-wait — waiting for minimum delay to expire before proceeding

Usage   Use this command to display how VLAGs are configured for activation in a cluster configuration.

Examples  To display cluster bring up activation, use the following syntax:

CLI network-admin@switch > cluster-bringup-show mode

state: vlags-enabled

mode: staggered

staggered-interval: 3s

minimum-delay: 0s

maximum-delay: 1m

The mode can be one of the following:
