4500X GLC-T and 100mbps support

[ring zer0]

Hi,

I am running a Cisco 4500X with 16 10G Fiber ports and I have used GLC-T on the ports to conver them to ethernet. I am using following IOS.

cat4500e-universalk9.SPA.03.06.04.E.152-2.E4.bin

When I try to change the speed of the port it doesnt change, there isnt any option. Will the GLC-T in this switch only operate at 1Gbps and I dont have an option to change the speed to 100mbps? I believe it should have 100/1000.

I believe it should have 100/1000.

Incorrect.  On a chassis-based system, including 4500X, 6880 & 6840, it is only 1 Gbps, full duplex.

I guess this support was added in IOS XE 3.7.1E and above.
