In Cisco ISR 1921 (Universal IPBASE) IOS don't have support for IP SLA operations except to act as IP SLA responder.
But yes in Cisco ISR 1921 (Universal DATA) IOS we have got the support for IP SLA operations and also in Cisco ISR 1921 (Universal Security) (Your preferred package of IOS) IOS too.
Regarding your question as what is IP SLA Responder?, please find the reply below.
Q.
What is the Cisco IOS IP SLA Responder?
A. When a Cisco Router has been designated to reply to Cisco IOS IP SLA test packets, configuring it to be a Cisco IOS IP SLA Responder provides greater accuracy in the measurements. The responder can utilize MD5 authentication for securing the control protocol exchange.
After the initial exchange, the responder can listen to Cisco IOS IP SLA test packets in the port requested by the Cisco IOS IP SLA source. Upon receiving the test packets, it captures the timestamps when the packets arrive, as well as when the replies leave. These timestamps help the Cisco IOS IP SLA source to make accurate assessments on one-way delay and the processing time in the target routers.
Cisco IOS IP SLA Responder can be enabled for the following operations:
• UDP Echo
• UDP Jitter
• TCP Connect
• Application Performance Monitor
• Video Operations
