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: https://standards.ieee.org/findstds/interps/IEEE802.3af-2003interp-6.pdf http://noahdavids.org/self_published/gigabit-AN.html
- 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. |
