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 explains the change in speed and duplex settings on FortiGate 10G ports (x1, x2, x3, and x4) after the firmware upgrade from v7.2.5 to v7.2.6.
Scope
FortiGate. Only 40xF and 60XF models are affected.
Solution
After upgrading from v7.2.5 to v7.2.6, the command 'set speed 1000auto' is no longer available in the interface settings of ports X1 - X4.
This firmware update results in the port speed reverting to 10G and potentially leading to connectivity issues.
The reported problem, identified by bug ID 967171, is slated for resolution on v7.2.7. It is important to note that the port speed was not intended to change during the firmware upgrade from v7.2.5GA to 7.2.6GA.
One workaround, for example, is to manually set the speed to 1000 full.
config system interface edit <interface name> set speed 1000full next
