I have a big problem with my 5508 WLCs and GLC-T sfps:

I'm currently using 2 ports of my WLC with GLC-T sfp I trieb using both LAG and multiple interface.

When I have all my copper cables connected between my LAN and my WLC everithing is ok but if I cut the cable on WLC port number 1 still shows link UP and stop forwarding traffic.

The apparatus works normally if I take away the sfp module when the cabel is cut.

I thank you very much

I have no idea what firmware you have but there is a known bug on the in regards to some of the Cisco SFPs are considered as "fake" or something.
