I've configured my two network interfaces : ETH0 and ETH1. ETH1 has 3
subinterfaces.
When I restart my server or just the network by 'service network
restart', my networks interfaces are no longer reachable.
I have to stop ETH0 and after ETH1. Then, I restart ETH1, I stop
ETH1:xxx1 and then the network is reachable. And finaly, I can restart
my ETH1:xxx1.
I feel like I have to restart interfaces in a certain order.
Do you have any ideas ?
Thanks in advance,

Is this CentOS 5.7 or 6? Have you looked in
/etc/udev/rules.d/70-persistant-net,rules, to see if something's out of
whack?

Network interfaces not reachable
Hi,
Can you further define "not reachable" with exact details?

Network interfaces not reachable
As a workround, u can automate your interface restart procedure on rc.local file.
And for troubleshooting, you need to put your interface config and script in the list so that we can analyze it, it's easier for us than just to predict what the actual problem is.
Thanks

nether the internet can ping my network interfaces.
2. @Mark : I use RHEL 6, I will look in '70-persistant-net'.
3. @FrankCui : Here my network interfaces config :
Can you further define "not reachable" with exact details?

Network interfaces not reachable
Dear All,
For your information. If the RHEL server setup within local area network. You may either configure each Network Interface card by:
1) Receiving IP address from nearest DHCP server appliance e.g network switches
2) Manual. By allocate exactly. Static IP address for each Network Interface card.
For manually configured static IP Address. You may refer the following command:
$ ifconfig eth0 xxx.xxx.xxx.xxx netmask yyy.yyy.yyy.yyy up
$*ifconfig eth1 xxx.xxx.xxx.xxx netmask yyy.yyy.yyy.yyy up
$*ifconfig *eth2 xxx.xxx.xxx.xxx netmask yyy.yyy.yyy.yyy up
*
where xxx = IPv4 static ip address
and yyy = IPV4 netmask ip address.
