Broadcom BCM 5722 don't ping the gateway

[Lisa Salvadorini]

Hi,

I have a Proliant DL 120 G5 with CentOS 5.4 and I have installed a Brodcom Corporation Netxtrem BCM 5722 Gigabit Ethernet PCI.
So I have two interfaces:
eth0 broadcom
eth1 Intel

The eth1 works, instead eth0 don't work.
I can ping itself and 127.0.0.1 but I can't ping the gateway.

What could be the problem?

Thankx

Could be anything. Please post the output of ifconfig eth0, mii-diag eth0, ethtool eth0, netstat -nr and the output of the ping command.

Thank you very much for the quick reply!

I show you the results of the command that you ask me.

I tried to remove the card Broadcom .. and it switches the interfaces:
eth0 intel
eth1: device eht1 has a MAC address different from the expected, operation ignored.

Now it doesn't work anything..

[Lisa Salvadorini]

I have found the problem.
The two nics were exchanged...
And the subnet for the two interfaces must be different..
