Error Message %SMART_LIC-3-AUTHORIZATION_INSTALL_FAILED: The install of a new
licensing authorization code has failed on [chars]: [chars].
This message is not applicable to Cisco Catalyst Access, Core, and Aggregation Switches, because there are
no enforced or export-controlled licenses on these product instances.

Error Message %SMART_LIC-3-COMM_FAILED: Communications failure with the [chars] :
[chars]
Explanation: Smart Licensing communication either with CSSM or with CSLU failed. The first [chars] is
the currently configured transport type, and the second [chars] is the error string with details of the failure.
This message appears for every communication attempt that fails.
Possible reasons for failure include:
• CSSM or CSLU is not reachable: This means that there is a network reachability problem.
• 404 host not found: This means the CSSM server is down.
For topologies where the product instance initiates the sending of RUM reports (Connected to CSSM Through
CSLU: Product Instance-Initiated Communication, Connected Directly to CSSM, and CSLU Disconnected
from CSSM: Product Instance-Initiated Communication) if this communication failure message coincides
with scheduled reporting (license smart usage interval interval_in_days global configuration command),
the product instance attempts to send out the RUM report for up to four hours after the scheduled time has
expired. If it is still unable to send out the report (because the communication failure persists), the system
resets the interval to 15 minutes. Once the communication failure is resolved, the system reverts the reporting
interval to the value that you last configured.
Recommended Action:
Troubleshooting steps are provided for when CSSM is not reachable and when CSLU is not reachable.
If CSSM is not reachable and the configured transport type is smart:
1. Check if the smart URL is configured correctly. Use the show license status command in privileged
EXEC mode, to check if the URL is exactly as follows: https://smartreceiver.cisco.com/licservice/license.
If it is not, reconfigure the license smart url smart smar_URL command in global configuration mode.
2. Check DNS resolution. Verify that the product instance can ping smartreceiver.cisco.com or the
nslookup translated IP. The following example shows how to ping the translated IP
Device# ping 171.70.168.183
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 171.70.168.183, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/2 ms
If CSSM is not reachable and the configured transport type is callhome:
1. Check if the URL is entered correctly. Use the show license status command in privileged EXEC mode,
to check if the URL is exactly as follows: https://tools.cisco.com/its/service/oddce/services/DDCEService.
2. Check if Call Home profile CiscoTAC-1 is active and destination URL is correct. Use the show call-home
profile all command in privileged EXEC mode:
