Cisco C9300-24S switch incorrectly configures port speed for SFP?

jeffreyfarrell

Level 1

I've got 14 GLC-GE-100FX SFP's in a 9300 switch. Ports 1-10 with these SFP's have the correct port speed setting (100Mb/s), but ports 11-14 have have the incorrect port setting of 1000Mb/s. I cannot manually change the port speed. What are my options?

Hello,

 

I am using third party curvature optics and cisco optics. The problem seems to come at random with both.
