bonding + vlan (without untagged address)
 

Hello,

I have a server with two network cards, each card is plugged on a switch
that as a default (untagged) network + a number of VLANs (tagged).


I'd like to bond the two interfaces and configure an IP address *only*
on a tagged network, not on the default one.


I tried to use "eth0", "eth1" and "bond0" as "dummy" interfaces with no
IP configured and "bond0.<vlan_ID>" as the real interface.


These are my configuration files :

/etc/modprobe.d/bonding.conf:
=============================
alias bond0 bonding
options bond0 mode=1 miimon=100

/etc/sysconfig/network-scripts/ifcfg-eth0
=========================================
DEVICE="eth0"
ONBOOT="yes"
BOOTPROTO="none"
SLAVE="yes"
USERCTL="no"
MASTER="bond0"

("ifcfg-eth1", is the same as "ifcfg-eth0 except" for the "DEVICE")

/etc/sysconfig/network-scripts/ifcfg-bond0
==========================================
DEVICE="bond0"
BOOTPROTO="none"
ONBOOT="yes"
USERCTL="no"

/etc/sysconfig/network-scripts/ifcfg-bond0.<vlan_ID>
================================================== ==
DEVICE="bond0.<vlan_ID>"
BOOTPROTO="dhcp"
ONBOOT="yes"
VLAN="yes"
USERCTL="no"

When I boot the server, eth0 and eth1 aren't going up, bond0 exists but
complains that eth0/eth1 are not present and bond.<vlan_ID> is not up.


If I connect to the server with a KVM console and manually start the
remaining interfaces (ifup eth0 / ifup eth1 / ifup bond0.<vlan_ID>, it
works!


If I configure a IP address for bond0, it also works at bootime, but I
don't want to do that.


Do you have an idea why eth0 and eth1 are not going up when bond0 as not
IP address? Again, it works if I manually start the interfaces.


I tried on Red Hat Enterprise Linux 5.6 and 6.0, both 64 bits edition.

Regards,

Nicolas

Any reason you aren't letting the switch control vlan access?

Because it's a test server, I will install on this server various OS on
various VLANs and I don't want to change the port configuration on both
switches each time.


The goal is to make the network configuration on the OS, cloning it, and
having the good (VLAN-ed) network at first boot.

[root@bbapp1 network-scripts]# cat ifcfg-bond0*
DEVICE=bond0
BOOTPROTO=static
ONBOOT=yes
TYPE=Ethernet

DEVICE=bond0.10
BOOTPROTO=static
IPADDR=158.135.1.21
NETMASK=255.255.254.0
GATEWAY=158.135.0.1
ONBOOT=yes
TYPE=Ethernet
VLAN=yes

DEVICE=bond0.650
BOOTPROTO=static
IPADDR=10.220.0.100
NETMASK=255.255.255.0
ONBOOT=yes
TYPE=Ethernet
VLAN=yes

[root@bbapp1 network-scripts]# cat ifcfg-eth*
DEVICE=eth0
ONBOOT=yes
TYPE=Ethernet
MASTER=bond0
SLAVE=yes

DEVICE=eth1
ONBOOT=no
TYPE=Ethernet
MASTER=bond0
SLAVE=yes

That's how we have a box set up to tag everything outgoing. I'm really not sure why eth1 is set to onboot=no... I'll have to look into it.

Hi,
If the onboot keeps no then Ethernet will not come up. You need to enable
it.
