Description

This article describes the reason of missing speed option settings in FortiGate D/E series with NP6.

Scope

FortiOS D/E series with NP6.

Solution

- Based on 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 FortoGate port needs to be set to auto negotiation and the neighbor switch port can be configured for 1000full.
