Hi, I have an issue with a number of Catalyst 2960 switches (ws--c2960-8tc-l). I want to use a 100FX SFP to connect the switch to the distribution layer. However when I use a GLC-GE-100FX module it error-disables the port and states SFP unsupported. That fine the cisco documentation states this is not supported. However I have also connected a GLC-FE-100FX and this work fine. Is this a supported configuration? The FE SFP is for 100mb port and the 2960 SFP port in Gigabit. I have 40+ of these little switches and I want to use on 100Mb uplinks. Please advise on the supportability of this configuration.
