Issue/Introduction
Design Decision: Configure the MTU size of the vSphere Distributed Switch to 9,000 for jumbo frames.
Resolution
Design Justification:
- Supports the MTU size required by system traffic types.
- Improves traffic throughput.
Design Implication: When adjusting the MTU packet size, you must also configure the entire network path (VMkernel ports, virtual switches, physical switches, and routers) to support the same MTU packet size.
