Setting a Search Path for Scripts

Create a path to the location where you stored the scripts. The Dell Networking OS uses this path when

searching for the scripts. This way you do not have to specify a specific path when executing a script.

• Set a search path for a script in the Dell Networking OS.

CONFIGURATION mode

script path path-name

The script path can contain a network file-system-mounted directory (defined in the mount nfs

command). The path is added to a script search list, allowing the system to search all locations for the

script name. If the script is in multiple locations, the system uses the first instance of the script found.

Scheduling and Executing Scripts

Schedule scripts to execute periodically, based on an event and a specific time, such as at boot up or

after you configure the switch.

Manage scripts to stop executing after a set time or to run at optimal times for critical resources, such as

switch CPU load or packet loss.

To access the Dell Networking OS CLI via scripts, the Dell Networking OS provides a utility called clido,

which is also a system command. For more information about the properties of clido, refer to Dell

Proprietary Utilities.

Script Scheduler from EXEC mode

To trigger scripts to run periodically or based on an event, use the following commands.

• Schedule a script to run in EXEC mode.

Schedule a script to execute at a specific time and optionally stop after a specified time. By default,

the script runs in the foreground. To run the script in the background, use the bg parameter.

EXEC mode

script execute script-name [start {at | date-time | after time}] [stop {at

date-time | after time}] [bg] [arguments arg[..arg]] [username username]

Following example shows the script execution at 22:22 10/30/14 (MM/DD/YY) and stops after 1 hour

and runs the script in the background:

Dell#script execute collect_log.py start at 22:22-10/30/14 stop after

0001:0000 args "Te 0/5" bg

– Scheduled scripts can be unconfigured/stopped/killed/resumed only by the configured user (test)

or higher privileged user.

– In general, the Privilege level 15 (highest privilege user in Dell Networking OS CLI) user can

configure/reconfigure the explicit username in script execute CLI.
