This MIB module defines the templates for IP SLA operations of ICMP echo, UDP echo and TCP connect. The ICMP echo operation measures end-to-end response time between a Cisco router and any IP enabled device by computing the time taken between sending an ICMP echo request message to the destination and receiving an ICMP echo reply. The UDP echo operation measures end-to-end response time between a Cisco router and any IP enabled device by computing the time taken between sending an UDP echo request message to the destination and receiving an UDP echo reply. The TCP connect operation measures end-to-end response time between a Cisco router and any IP enabled device by computing the time taken to perform a TCP connect operation.
