The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product. Learn more about how Cisco is using Inclusive Language.

The following example shows how to request a configuration from a trusted server at 10.1.1.1 and to configure a Cisco Networking Services configuration retrieve interval using the cns config retrieve command:
cns trusted-server all 10.1.1.1 exit cns config retrieve 10.1.1.1 retry 50 interval 1500 CNS Config Retrieve Attempt 1 out of 50 is in progress Next cns config retrieve retry is in 1499 seconds (Ctrl-Shft-6 to abort this command). .. 00:26:40: %CNS-3-TRANSPORT: CNS_HTTP_CONNECTION_FAILED:10.1.1.1 -Process= "CNS config retv", ipl= 0, pid= 43
00:26:40: %CNS-3-TRANSPORT: CNS_HTTP_CONNECTION_FAILED -Process= "CNS config retv", ipl= 0, pid= 43......
cns config retrieve 10.1.1.1
The following example shows how to check and apply configuration data retrieved from the server to running configuration file only. The Cisco Networking Services Configuration Agent will attempt to retrieve configuration data at 30-second intervals until the attempt is successful, or is unsuccessful five times in these attempts.
cns config retrieve 10.1.1.1 syntax-check no-persist retry 5 interval 30
The following example shows how to overwrite the startup configuration file with the configuration data retrieved from the server. The configuration data will not be applied to the running configuration.
cns config retrieve 10.1.1.1 syntax-check no-persist retry 5 interval 30 cns config retrieve 10.1.1.1 overwrite-startup
