Description
This article describes the Interface groups and changing data interface speed.
Scope
FortiGate v7.2, v7.4, v7.6.
Solution
FortiGate-6000F port speed change is always applied to a group of 4. Groups are: port1-port4, port5-port8, port9-port12, port13-port16, port17-port20, port21-port24.
Note:
All of the interfaces in a group operate at the same speed. Changing the speed of an interface changes the speeds of all of the interfaces in the same group.
config system interface
edit "port1"
set vdom "root"
set ip 10.X.X.X 255.255.255.0
set allowaccess ping https ssh http telnet
set type physical
set mediatype sr
set snmp-index 1
set speed 10000full
next
end
FGT (port1) # set speed 25000full
FGT (port1) # end
port1 - port4 speed will be changed to 25000full due to hardware limit.
Do want to continue? (y/n)
For example, change the speed of port1 from 10Gbps to 25Gbps the speeds of port2 to port4 are also changed to 25Gbps because port1-port4 are grouped.
FGT(global) # show system interface port1 | grep speed
set speed 25000full
FGT(global) # show system interface port2 | grep speed
set speed 25000full
FGT(global) # show system interface port3 | grep speed
set speed 25000full
FGT(global) # show system interface port4 | grep speed
set speed 25000full
FGT(global) # show system interface port5 | grep speed
set speed 10000full <---- No change to port different group.
Note:
Port25 to Port28 interfaces are not part of an interface group and can be configured these interfaces independently of the other interfaces.
config system interface
edit "port28"
set vdom "root"
set allowaccess ping fgfm
set type physical
set mediatype sr
set snmp-index 28
set speed 40000full
next
end
FGT(port28) # set speed 100Gfull
FGT(port28) # end
config system interface
edit "port28"
set vdom "root"
set allowaccess ping fgfm
set type physical
set mediatype sr
set snmp-index 28
set speed 100Gfull
next
end
