Hello, I'm curious about the technology of
ipsla
Please refer to the config below and explain it.
configure terminal
!
ipsla

Hello @sjrcoel,
The configuration you've provided appears to be related to
ipsla
and specifically the use of Two-Way Active Measurement Protocol (TWAMP) Light for network performance monitoring.
TWAMP Light is an extension of
IP SLA
that allows for measuring network performance metrics in a simplified manner.
Your
ipsla
configuration in details:
ipsla responder
This command is used to enable the
IP SLA
responder feature on the device. The responder is used to respond to
IP SLA
test sessions initiated by another device acting as the sender.
twamp-light test-session 3
This command initiates the configuration for a TWAMP Light test session with session number 3. TWAMP Light is an efficient method for measuring network performance metrics like round-trip time (RTT).
local-ip 198.18.57.84 local-port 13000
This command sets the local IP address
(198.18.57.84) and port (13000)
to be used as the source for this TWAMP Light test session.
remote-ip 198.18.57.254 remote-port 13001
This command sets the remote IP address
(198.18.57.254) and port (13001)
to be used as the destination for this TWAMP Light test session.
vrf default
This command specifies the default VRF to be used for this test session.
You've set up an
ipsla
responder to respond to TWAMP Light test sessions. These test sessions are initiated by another device (the sender) and are used to measure network performance between the local and remote IP endpoints. The results of these test sessions can be used to monitor network performance and diagnose network issues.
This configuration is used in conjunction with a TWAMP Light sender on another device to conduct network performance tests. The sender initiates the tests, and the responder (configured here) responds to the tests, allowing measurement of network performance metrics.

In general, it defines mini performance tests, between Cisco devices, that are run on some repetitive schedule, and results are recorded.
Lot more information available on Cisco's main site. Perhaps start here: https://www.cisco.com/c/en/us/products/ios-nx-os-software/ios-ip-service-level-agreements-slas/index.html

BTW, M02@rt37's reply is a excellent description of the IPSLA config snippet you posted. Your posted IPSLA is a relatively recent feature enhancement.
The Cisco IPSLA technology has been available for some time although not initially known as IPSLA. You might find https://community.cisco.com/t5/routing/rtr-and-sla/td-p/1177765 of interest.
