Kaspersky SD-WAN

Package fragmentation

Kaspersky SD-WAN checks whether fragmentation of traffic packets is supported on CPE devices. A packet fragmentation test is started automatically. When each CPE device is enabled, it sends two ICMP requests to the IP addresses that you specified when creating or editing SD-WAN interfaces of the WAN type.

The ICMP requests have a packet size of 1600 bytes. If at least one of these requests receives a response, a conclusion is made that the CPE device supports packet fragmentation. You can view the fragmentation test result in the Fragmentation column of the CPE device table or the link table.
