I've read that those switches should support 100BASE-X, but in my case they wont.</P><P>I think maybe i have wrong SFP modules - i have tried EDGE sfps (i've had positive experiences between edge sfps and Extreme switches).</P><P>For MultiMode i got - EDGE 155M-SFP-2D-EX&nbsp;</P><P>For SingleMode i got - EDGE 155M-SFP-15D-EX (MGBIC-LC05)</P><P>In other end its usually IP cameras or RJ45-Fiber converters. I can see "show port conf no-refersh" that media "!100LX10". I know that ! means unsupported, but in my case i've seen even when ! in front 1gig sfps works fine. I've tried change speed "auto off speed 100 duplex full", but nothing.</P><P>Theres no link coming up when Fiber is connected with SFPs. Does switch also say ! - unsupported when in other end is unsupported or only for that what is connected directly to switch.</P><P>In my case is there problem with FO converter which can not undrerstand switch sfp?</P><P>1G and 10G works super fine.</P><P>Thank you!</P> Thu, 23 Feb 2023 07:29:53 GMT JaxN 2023-02-23T07:29:53Z https://community.extremenetworks.com/t5/extremeswitching-exos-switch/trouble-to-get-100base-x-sfp-to-work-on-x465-24s/m-p/94834#M21778 <P>Hello community,</P><P>I'am using 2 x456-24s Extreme Fiber switches.
