My firewall is based linux and with kernel of 2.4.18, and when I connected Fiber port on the firewall with Switch I found a strange problem; as you know fiber port will automatically setting the speed with 1000M,and duplex with full,if connetcted, But I am confused with the function of autoneg, By default the autoneg for this fiber port is settled with Off, But after I turned autoneg on with the ethtool I found I can not turn this back to OFF, Only after reboot the system autoneg will turn to off. shown as below: / >ethtool eth1 (this is fiber 1000sx port) Settings for eth1: Supported ports: [ FIBRE ] Supported link modes: 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 1000baseT/Full Advertised auto-negotiation: Yes Speed: 1000Mb/s Duplex: Full Port: FIBRE PHYAD: 0 Transceiver: internal Auto-negotiation: off Supports Wake-on: umbg Wake-on: d Link detected: yes But after I tunrned the autoneg to ON: ethtool -s eth1 autoneg on I can not make the autoneg for this port turn back to OFF; even I input the command; ethtool -s eth1 aotuneg off It wil do nothing; Only after reboot the system,It will be back to Off. Is this a bug for this kernel?or for ethtool ? Thanks for your help. from kent
