To configure a delay for acting upon a track object reachability state changes, use the delay command in Track configuration mode.
| Default | None |
| Format | delay {up seconds [down seconds] | [down seconds] up seconds} |
| Mode | Track Config |
| Parameter | Description |
|---|---|
| up seconds | Time to delay the notification of an up event. Delay value, in seconds. The range is from 0 to 180. The default is 0. |
| down seconds | Time to delay the notification of an down event. Delay value, in seconds. The range is from 0 to 180. The default is 0. |
Usage Guidelines
To minimize flapping of the reachability state (Up/Down), use the delay command to introduce a non-zero delay in seconds between the UP and DOWN state transitions per Track object.
Delay time specifies the hold interval for an (UP/DOWN) state before taking action on the associated static routes.
Example: In the following example, Track object 10 is created and is associated with the IP SLAs operation 11 and then an up delay of 5 seconds and a down delay of 3 seconds is configured:
(Routing)(config)#track 10 ip sla 11 (Routing)(config-track)#delay up 5 down 3
