By default, the 10G fiber ports on EXOS switches have the port setting to auto negotiation off and speed 10000 duplex full.
If we insert a 1G - 1000 BaseT optic, the following warning is thrown and the speed is auto-corrected for this optic.
04/07/2004 14:53:06.32 <Warn:HAL.Port.OpticCfgCflct> Slot-1: The configuration for the 1000T optic module is not correct - please configure port 1:9 for auto-negotiation On and speed 1000
04/07/2004 14:53:06.41 <Info:vlan.dbg.info> Slot-1: Port 1:9 was changed to auto negotiation on due to 1000BaseT GBIC.
After this change, the port speed is currently set to auto negotiation on speed 1000.
If an 10G SFP+ optic is now inserted, the link does not become active with the following warning.
04/07/2004 14:07:41.34 <Info:vlan.dbg.info> Media SF+_SR is inserted into Port 9
04/07/2004 14:07:41.34 <Warn:HAL.Port.OpticCfgCflct> The configuration for the SF+_SR optic module is not correct - please configure port 9 for auto-negotiation Off and speed 10000
The settings has to manually changed to auto negotiation off and speed 10000 for the link to be active.
