Symptom

The IOS-XE version starting from 17.7.1 and up offers the ability to use Tier-based throughput instead of Numeric. https://www.cisco.com/c/en/us/td/docs/routers/C8000V/Configuration/c8000v-installation-configuration-guide/m-available-licenses.html c8000v(config)#platform hardware throughput level MB ? 100 Mbps 1000 Mbps 15 Mbps 25 Mbps 250 Mbps 50 Mbps 500 Mbps T0 Tier0(up to 15M throughput) T1 Tier1(up to 100M throughput) T2 Tier2(up to 1G throughput) When a Tier-based throughput is chosen as an option, the license consumption of every use of "license boot level throughput level MB T?" increases the license consumption. Example of 3 x network-essentials_250M and dna-essentials_250M licenses consumed after applying any Tier based throughput level, test with: c8000v(config)#platform hardware throughput level MB T2 Router(config)# Router(config)# *Sep 23 17:07:47.439: %SMART_LIC-3-AUTHORIZATION_INSTALL_FAILED: The install of a new licensing authorization code has failed on PID:C8000V,SN:XXXXXXXXXXX: ERROR_INSUFFICIENT_LICENSES.

Conditions

Affects only c8000v virtual Edge. Using Tier-based throughput levels with IOS-XE versions starting from 17.7.1 and up Example: c8000v(config)#platform hardware throughput level MB T2 Affected IOS-XE releases: - 17.7.1a, 17.7.2 - 17.8.1a - 17.9.1a

Workaround

1. Using numeric throughput instead of Tier-based Example: c8000v(config)#platform hardware throughput level MB 500 2. Offline registration to CSSM will help with this if performed only once. Any subsequent offline report will increase the consumption on CSSM Will be fixed with IOS-XE versions above 17.7.X, starting from: - 17.9.2 - 17.10.1
