My customer connected a 2960G-48TC-L to a preconfigured C1841 router. The router was hard coded to 10 Full and the 2960G to auto/auto. The 2960G would only auto configure to 10 Half. Hard coding the 2960G to 10 Full knocked down the link as did setting both ports to 100 Full. After several changes the best we could achieve was 100 Full by setting the 2960G to Auto/Auto and the 1841 to Full/Auto. I've unsuccessfully looked though tech notes to see if I could find anything on this specific combination. Has anyone experienced similar issues?
I have this problem too.
