bring interface physically down
I have a following simple topology: Cisco2960[Fa0/1] <-> [eth0]server. eth0 is using e1000e(Intel(R) PRO/1000 Network Driver, version 1.4.4-k) module. Is it possible to bring eth0 down in a way that switch port Fa0/1 shows not-connected? I tried with "ip link set eth0 down" and "modprobe -rv e1000e", but the Fa0/1 is still up. One option would be to force eth0 to 1000BASE-T mode while switch port does not support this. In addition, it's possible to execute offline tests to eth0 interface with "ethtool -t eth0" command, which will bring interface down for few seconds. However, is there an option to bring interface permanently physically down?
