Route policy damping commands

damping

Syntax

[no] damping name

Context

config>router>policy-options

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures a route damping profile to use in route policy entries.

The no form of this command deletes the named route damping profile.

Parameters

name

Specifies the damping profile name. Allowed values are any string up to 32 characters composed of printable, 7-bit ASCII characters. If the string contains special characters (#, $, spaces, and so on), the entire string must be enclosed within double quotes.

half-life

Syntax

half-life minutes

no half-life

Context

config>router>policy-options>damping

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures the half life value for the route damping profile.

The half life value is the time required for a route to remain stable in order for the Figure of Merit (FoM) value to be reduced by one half; for example, if the half life value is 6 (minutes) and the route remains stable for 6 minutes, the new FoM value is 3 (minutes). After another 3 minutes pass and the route remains stable, the new FoM value is 1.5 (minutes).

When the FoM value falls below the reuse threshold, the route is again considered valid and can be reused or included in route advertisements.

The no form of this command removes the half life value from the damping profile.

Parameters

minutes

Specifies the half life, in minutes, expressed as a decimal integer.

Values

1 to 45

max-suppress

Syntax

max-suppress minutes

no max-suppress

Context

config>router>policy-options>damping

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures the maximum suppression value for the route damping profile.

This value indicates the maximum time that a route can remain suppressed.

The no form of this command removes the maximum suppression value from the damping profile.

Parameters

minutes

Specifies the maximum suppression time, in minutes, expressed as a decimal integer.

Values

1 to 720

reuse

Syntax

reuse integer

no reuse

Context

config>router>policy-options>damping

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures the reuse value for the route damping profile.

When the FoM value falls below the reuse threshold, the route is again considered valid and can be reused or included in route advertisements.

The no form of this command removes the reuse parameter from the damping profile.

Parameters

integer

Specifies the reuse value, expressed as a decimal integer.

Values

1 to 20000

suppress

Syntax

suppress integer

no suppress

Context

config>router>policy-options>damping

Platforms

Supported on all 7210 SAS platforms as described in this document

Description

This command configures the suppression value for the route policy damping profile.

A route is suppressed when it has flapped frequently enough to increase the FoM value to exceed the suppress threshold limit. When the FoM value exceeds the suppress threshold limit, the route is removed from the route table or inclusion in advertisements.

The no form of this command removes the suppress value from the damping profile.

Parameters

integer

Specifies the suppress value, expressed as a decimal integer.

Values

1 to 20000
