IP SLA on Cisco 1921 IOS 15.2T
5,230
As said in the comment, the Universal software image has its command set limited by the Feature licences installed. the IP SLA command is available in the "Advanced IP Services feature license". You may check which licences you have available with the command "sh licence"

Can someone explain to me why I cannot create IP SLA probes on a Cisco 1921 with the latest IOS (15.2T). It is clearly available for that IOS on that router model on the Cisco Feature Navigator ...

Flash over 12 yearsNot very much experience with the 15.x software yet. but to my understanding the "universal" image you are running supports all features, however the available features are limited by the licences activated. Have a look at this link from Cisco aswell cisco.com/en/US/prod/collateral/modules/ps10598/… the specific licence "IP SLA" falls under is unknown, but your cisco reseller will be able to answer this.
