FortiGate Next Generation Firewall utilizes purpose-built security processors and threat intelligence security services from FortiGuard labs to deliver top-rated protection and high performance, including encrypted traffic.
This article describes the situation when all data interfaces on all VMX security nodes are set with speed and duplex 10full.
Scope
Solution
Sometimes speed and duplex settings of the data interfaces on the VMX nodes can lead to misunderstanding.
For example:
FortiGate-VMX (global) # diagnose hardware deviceinfo nic internal Name: internal Driver: tun Version: 1.6 FW version: N/A Bus: tap Hwaddr: 02:69:65:d1:60:52 State: up Link: up Mtu: 65521 Supported: Advertised: Speed: 10full
It is expected behavior.
Data interfaces are virtual interfaces, therefore the speed/duplex definition of a regular physical interface is not applicable to the virtual interface.
The actual speed of the virtual data interfaces depends on the physical layer of the hypervisor.
