stop 9200 switches to try connect to Cisco

[Mohammad Ramadan A.Hafiez]

Hi,

       I have Cisco 9200 switchs in my data center and I have licensed these switches, even though these switches keep trying to access internet for licenses and firewall blocks it.

plus other logs for security keys and saving it.

I want to stop this un-needed logs abd process by the switches.

logs sample...

Smart License required port access to call Home access - you need to open http/https connection towards cisco site.

or ignore the errors.

but bare in mind as per i know, if they can not have communicaiton to smart License server, some feature may disable due to error connecting to cisco side (this was not tested but as per process).

Hello,

check if the bug below applies:

Smart License registration fails with "Fail to send out the Call Home HTTP message" with http-proxy
CSCvd38363
Description
Symptom:
Smart Licensing registration may fail. A message similar to the following may be found in syslogs:

Feb 22 17:33:53.487 PST: %SMART_LIC-3-COMM_FAILED: Communications failure with Cisco licensing cloud: Fail to send out Call Home HTTP message.

Conditions:
This symptom is observed when an HTTP proxy server is configured for call-home. The following example config would be found under the call-home profile:

call-home

http-proxy "1.2.3.4" port 80

The address of the proxy and the port do not have any bearing on the problem.

Workaround:
Smart Licensing registration will succeed if the HTTP proxy configuration is removed.

If the proxy is required for the device to reach tools.cisco.com over HTTP/HTTPS, then there is no workaround.

Thank you for the bug notification, but my switches have successfly registered but still keeping logging to internet trying to register.

I want to stop this traffic to internet because whenever i want to debug any service it keeps filling the screen with this events.

Upgrade the firmware first.
