Description |
This article describes that ULL (Ultra Low Latency Slots) which are supported for 25GE /SFP28 interface can detect 25GB transceiver, but the interface setting does not show 25Gbps speed as an option. |
Scope |
NP7 Platform, v6.2.x and above. |
Solution |
ULL interface is marked to 10 Gb by default, to enable 25 Gb speed, an NPU level command is required.
For Devices with VDOMS, log in as super_admin and modify the settings user: config system global config system npu
Before:
config system npu set ull-port-mode 10G end
ULL interface:
MID-FG601F-01 (x6) # set speed 10000full 10G full-duplex.
diagnose npu np7 port-list
x1 10000 10000 n/a 0 6 x2 10000 10000 n/a 0 7 x3 10000 10000 n/a 0 4 x4 10000 10000 n/a 0 5 x5 10000 10000 n/a n/a n/a n/a x6 10000 10000 n/a n/a n/a n/a x7 10000 10000 n/a n/a n/a n/a x8 10000 10000 n/a n/a n/a n/a -------- --------------- --------------- --------------- --------- ----------
After:
config system npu set ull-port-mode 25G end
MID-FG601F-01 (x6) # set speed 25000full 25G full-duplex.
diagnose npu np7 port-list x1 10000 10000 n/a 0 6 x2 10000 10000 n/a 0 7 x3 10000 10000 n/a 0 4 x4 10000 10000 n/a 0 5 x5 25000 25000 n/a n/a n/a n/a x6 25000 25000 n/a n/a n/a n/a x7 25000 25000 n/a n/a n/a n/a x8 25000 25000 n/a n/a n/a n/a
A reboot will automatically take effect. Choose to change the interface speed. In case of a cluster, all cluster members will be rebooted simultaneously, therefore, a maintenance window is required.
NP7 ULL port mode speed change will take effect after the system reboot.

To validate whether an interface is supported or not, look up the datasheet for the product. In this instance, it is for a FortiGate-601F with ULL interfaces supported. Interfaces are X5 to X9, where one could only set 10Gb speeds, although the interface supports 25Gb. This is only supported on interfaces that support 25GE. |
