有谁知道两台机器lan0互连有时通有时不通的原因?
[quote]原帖由 "dman_lou"]n4000的lan0和l3000的lan0用反接线连接,做心跳用,两台机器同时启动,那么这两个网卡之间就ping不通,如果一台机器up,另一台机器重起则没有问题,不知道是什么问题造成的,问hp工程师他说就是这样,不建议两个网卡..........[/quote 发表:
Hi,
If you need to direct connect 2 lan cards (on two different system), then you have two options:
1. Use one "cross-over" ethernet cable to connect two systems.
2. Use two "straight" ethernet cables (the common one) on each card, then connect them through a hub or switch. The hub/or switch will internally "cross-over" the connections.
You have to understand that the regular cables we are using are all "straight", they are only good when you use them to connect the system to hub or switch. If you connect 2 systems with a cable like this, then the "send" pin on system1 will try to talk to the "send" pin on system2. This is not going to work. The "send" pin on system1 should talk to the "receive" pin on the system2.
Hope this explains. The suggestion that HP engineers gave was right, follow their instructions.
Thanks, |
