The Global Configuration page includes controls that allow you to view traffic statistics and manage Maximum Transmissible Unit (MTU) and Unicast Reverse Path Forwarding (URPF) settings for SDDC network uplinks.
In the default configuration:
- The MTU for the Services uplink (which carries traffic to the connected VPC) is set to 8900 bytes. The MTU for other uplinks is set to 1500 bytes.
- URPF is applied in Strict mode and packets are forwarded to SDDC uplinks only if they are received on the interface that provides the best reverse path to the source of the packet. Packets that do not meet this criterion are dropped.
