Technical Tip: 4x100G Split Mode Interface Does Not Display the Correct Speed
| Description | This article provides a solution for an issue where the interface media type is incorrectly displayed when configuring a 4x100G split-port mode on FortiGates. |
| Scope | FortiGates supporting split port functionality and running v7.2.8. |
| Solution | When a split port is configured on a port, 50G interface speed is seen instead of 100G in the interface media-type output. config split-port-mode edit "port25" set split-mode 4x100G next end get sys interface media-type port25/1 port25/1 : 50G-Fiber-multi_interface get sys interface media-type port25/2 port25/2 : 50G-Fiber-multi_interface get sys interface media-type port25/3 port25/3 : 50G-Fiber-multi_interface get sys interface media-type port25/4 port25/4 : 50G-Fiber-multi_interface The correct speed is seen in the below outputs: show system interface port24/1 config system interface edit "port25/1" set vdom "3py" set type physical set snmp-index 55 set speed 100Gfull set mediatype sr2 set forward-error-correction cl91-rs-fec next end get sys interface physical port24/1 == [onboard] ==[port25/1] mode: static ip: 0.0.0.0 0.0.0.0 ipv6: ::/0 status: up speed: 100000Mbps (Duplex: full) FEC: cl91-rs-fec FEC_cap: {disable} This is just a media-type display issue and does not impact the port functionality. The issue has been resolved in FortiOS version 7.6.1. |
