Abstract
Technologies are provided for active monitoring of network fabrics, such as border network fabrics. For example, test packets can be generated and sent to destination devices within the network fabrics. The test packets can have destination ports that have been identified as closed destination ports. The success of the test packets can be determined based on whether ICMP error packet responses are received. If a network problem is detected based on results of the test packets, then traceroute packets can be used to identify the location of the network problem.
