Statement introduced before Junos OS Release 7.4.
Command introduced in Junos OS Release 10.4R5 for EX Series switches.
Command introduced in Junos OS Release 11.1 for the QFX Series.
Statement introduced in Junos OS Release 12.2 for ACX Series Universal Access Routers.
Specify the 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.
NOTE:
We recommend that you configure the
an appropriate value by performing repeated tests in the actual hardware
environment. This is because the appropriate value for
