Short answer: use ethtool to force 10Mb/s half-duplex on the interface. As asked, that is done per-interface and must be done with root privileges. As pointed out, distribution details vary, and shared a link — below are concise, practical steps and tips.

Find the interface name and force the speed (example uses eth0 — replace with your device name):

ip link show
sudo ethtool -s eth0 speed 10 duplex half autoneg off
sudo ethtool eth0

The final ethtool run verifies the link settings (Speed, Duplex, Auto-negotiation). If the -s command fails with "Operation not supported" or has no effect, the NIC/driver or PHY may not allow manual forcing. Check dmesg for driver messages, update the driver/firmware, or consult the NIC vendor driver docs.

To make the change survive reboots use your distro’s network hooks (NetworkManager dispatcher scripts, ifupdown pre-up, systemd unit, or networkd). Example systemd oneshot service:

[Unit]
Description=Force 10Mbps half duplex on eth0
After=network-pre.target
Before=network.target

[Service]
Type=oneshot
ExecStart=/sbin/ethtool -s eth0 speed 10 duplex half autoneg off
RemainAfterExit=yes

[Install]
WantedBy=multi-user.target

Caveats: forcing half-duplex disables auto-negotiation and can cause collisions and poor performance; use it only when required (old hubs/switches or test situations). Prefer auto-negotiation where possible. See the ethtool manual and kernel ethtool documentation for full option details: ethtool man page and .

secondly its not "linux enterprise"

there is thousands of different linuxes

i beloeve what you mean is either SuSE or Redhat

also, why do you want to slow it down

if your cables and hubs are of the slower speed your card will automatically slow itself down
