Severity: 3-Major


Inserting a 40G optic into a 100G port, or inserting a 100G optic into a 40G shows the optic as "Unsuported Optic". That is not correct, it may be a supported optic, just inserted in the wrong port.


The user may be confused on why the optic is not working, the error message is misleading when the optic is inserted in the wrong port.


B4450 Blades with 100G or 40G optics inserted in a port that does not support that speed optic.


If the optic shows up in "tmsh list net interface" as "Unsuported Optic" remove the optic and verify that the optic speed matches the port.

Fix Information

The "tmsh list net interface" will now show: module-description "F5 Qualified Optic in invalid port" And the LCD warning message will show: Optic OPT-XXXX not valid in Interface <InterfaceNumber>.
