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 reason of missing speed option settings in FortiGate D/E series with NP6 and the FortiGate G series with NP7lite.
Scope
FortiOS D/E/F series with NP6 and FortiOS G series with NP7lite.
Solution
Based on the standard, auto-negotiation of copper port is mandatory for 1G speed, therefore manually forcing 1G speed in CLI is no longer supported, this option has been removed permanently:
FortiGate-1100E (port1) # set speed
auto <----- Automatically adjust speed.
100full <----- 100M full-duplex.
Due to this, the option is not available in the copper ports, but in the optical ones it is possible to configure:
FortiGate-1100E (port25) # set speed
1000full <----- 1000M full-duplex.
10000full <----- 10G full-duplex.
More information can be found in the following sites:
If the port needs to negotiate a 1G speed, the FortiGate port needs to be set to auto negotiation and the neighbor switch port can be configured for 1000full.
