Configuring fiber interfaces during an ODA installation can sometime been challenging. The configuration can depend on the kind of gigabit interface converter (GBIC) and switch been used. In this blog, I would like to show a real case faced during one of our customer deployment, and come with a solution.<\/p>\n
<\/p>\n
We were facing link detection issue when using the GBIC converter delivered by ORACLE, although using a CISCO GBIC converter could make the link available.
\nem2 interface was used with a CISCO GBIC.
\nem3 interface was used with an ORACLE GBIC.<\/p>\n

Solution<\/h2>\n
Forcing the interface on 10 Gb and configuring auto-negotiation to false could solve the link detection issue with the ORACLE GBIC converter.
\nThis has been performed by updating both ifcfg-em2 and ifcfg-em3 (stored in \/etc\/sysconfig\/network-scripts) with :<\/p>\nETHTOOL_OPTS=\"speed 10000 duplex full autoneg off\"<\/pre>\n<\/p>\n
Both links could then be detected successfully.<\/p>\n

SFP28 Ethernet Controller firmware upgrade<\/h2>\n
The firmware version we were running is the 20.06.04.06.<\/p>\n
