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
