Хочу ограничить скорость подключения со 100 до 10.
при вводе команды c параметром autoneg off
# ethtool -s eth0 speed 10 duplex full autoneg off
Cannot set new settings: Invalid argument
not setting speed
not setting duplex
not setting autoneg
Если параметр убрать, то настройки скорости не меняются.
Если изменить на autoneg on то пропадает соединение, а ethtool eth0 выдает
Settings for eth0:
Supported ports: [ TP ]
Supported link modes: 10baseT/Half 10baseT/Full
100baseT/Half 100baseT/Full
Supports auto-negotiation: Yes
Advertised link modes: 10baseT/Full
Advertised auto-negotiation: Yes
Speed: Unknown! (65535)
Duplex: Unknown! (255)
Port: Twisted Pair
PHYAD: 0
Transceiver: internal
Auto-negotiation: on
Supports Wake-on: g
Wake-on: d
Current message level: 0x00000000 (0)
Link detected: no
То есть Speed и Duplex вообще не устанавливаются
