hold-time

hold-time (physical interface)

Syntax

hold-time up milliseconds down milliseconds;

Hierarchy Level

[edit interfaces interface-name]

Description

Hold-time value to use to damp interface transitions. When an interface goes from up to down, it is not advertised to the rest of the system as being down until it has remained down for the hold-time period. Similarly, an interface is not advertised as being up until it has remained up for the hold-time period.

Default

Interface transitions are not damped.

Options

down milliseconds—Hold time to use when an interface transitions from up to down. Upon execution, the time value that you specify is rounded up to the nearest whole second; therefore, we recommend that you configure the down option to multiples of 1000.
Range: 0 through 65,534
Default: 0 milliseconds (interface transitions are not damped)

up milliseconds—Hold time to use when an interface transitions from down to up. Upon execution, the time value that you specify is rounded up to the nearest whole second; therefore, we recommend that you configure the up option to multiples of 1000.
Range: 0 through 65,534
Default: 0 milliseconds (interface transitions are not damped)
