If you don't get errors I'd make that part of the boot process as well as the network scripts if you restart your interfaces often. I tried that and didn't work.

[gentoo-user] Gigabit NIC but only 100baseT/Full working
Hi all! I have two servers here with two Intel E1000 NIC each. I'm planing on using the eth1 ethernet with DRBD. My problem is that although the NICs support gigabit ethernet, they only negociate with 100baseT/Full. I'm using a CAT-5E crossover cable between the servers. Here is my dmesg (both servers): e1000: eth1: e1000_probe: Intel(R) PRO/1000 Network Connection e1000: eth1: e1000_watchdog: NIC Link is Up 100 Mbps Full Duplex My ethtool shows the following (both servers): Settings for eth1: Supported ports: [ TP ] Supported link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Supports auto-negotiation: Yes Advertised link modes: 10baseT/Half 10baseT/Full 100baseT/Half 100baseT/Full 1000baseT/Full Advertised auto-negotiation: Yes Speed: 100Mb/s Duplex: Full Port: Twisted Pair PHYAD: 0 Transceiver: internal Auto-negotiation: on Supports Wake-on: umbg Wake-on: g Current message level: 0x0007 (7) Link detected: yes Does anyone have any tip?

Re: [gentoo-user] Gigabit NIC but only 100baseT/Full working
From my understanding thats not a problem with the OS, but with the crossover cable itself. The os is seeing it as a Gigabit card. I believe a cat6 cable will work and give you the right speed, you may want to try that. Alternativly, the following should work if you crimp one yourself.

Thanks Rick, I'm going to try that tomorrow. I thought CAT5e cable would support gigabit connections.

The cable has to be good though. I know I've had at least one cable that looked perfectly fine, worked perfectly at 100meg, but would never auto-negotiate at 1gig. -- Mike Williams -- gentoo-user@gentoo.org mailing list
