Hi

We have two Blade center C series servers, who used to run vmware esx, but we are now moving away from vmvare, so I've reinstalled the two server with CentOS 5.4 X86_64.
It all vent fine, but now I'm stuck with the network configuration.
The blades are connected to two switches where 5 VLAN (1 LAN and 4 DMZ) have been created.

When I boot up the new OS, I see eth0 NIC, but configuring eth0 does not give me a connection. I've tried creating several VLANs but that didn't work either.

When the server was running vmware, eth1 had this configuration

Can anyone give me som pointers?
What am I missing, a virtual switch or something like that?

regards Søren

can you see *any* traffic passing over eth0?? -- tcpdump??
can you ping the def gw??
can you show the /etc/sysconfig/network-scripts/ifcfg-eth0 config and /etc/sysconfig/network ??

/etc/sysconfig/network shows:
NETWORKING=yes
NETWORKING_IPV6=no
HOSTNAME=Odense06
GATEWAY=192.168.1.2
GATEWAYDEV=eth0

/etc/sysconfig/network-scripts/ifcfg-eth0 shows:
DEVICE=eth0
ONBOOT=yes
BOOTPROTO=static
HWADDR=00:1B...etc.
TYPE=Ethernet
IPADDR=192.168.1.3
NETMASK=255.255.255.0

I have also tried adding BROADCAST, NETWORK and GATEWAY, but no help.


I am getting lots of things in tcpdump.
Mostly "arp who-has" and "IP 192.168.1.42 bootpc > 255.255.255.255 ..."

can i see the output of route -n as well??


can you ping the gateway device??
need the output of that too

route -n

can you ping gateway?
the reason i ask all this is because i have a similar set up

No, I can't ping anything.
This might be a network issue. This server used to be a production server, so it's on a high level security.
I just don't get why it's not working when I'm using the same IP addresses and MAC address as were on the ESX server it's replacing.

Did you need any additional drivers when installing the OS?

if you have ethtool utility, please post output for "ethtool eth0"

And check ethernet cable - it should be straight, because you connect NIC to router.

ethtool eth0 shows:

Supported ports: [ FIBRE ]

I think the vlan is misconfigured....
