half duplex connectivity

[james1212]

I have cisco 4507 with  ipbase-mz.122-54.SG and i have one weird case with Samsung notebook

a few (not all) Samsung note have 100/half connectivity with this switch.

if i connect other laptop with this same port, it connects with 1000/full

if I connect the Samsung laptop with other switch, it connects with 1000/full

does anyone ever have this issue?

thanks

check windows NIC driver settings on the laptop? They could be set manually to 100/full which will result in your behavior. If you see them set to auto, update NIC drivers.
