Configure VLAN Based on Bond Adapters
The following example sets the xCAT properties for compute node cn1
to create:
Compute node
cn1
with two physical NICs:eth2
andeth3
Bond eth2 and eth3 as
bond0
Create bridge
bond0.1
based onbond0
Assign ip
40.0.0.1
to the bridge interfacebond0.1
Add network object into the networks table
Add/modify the network net40
in the networks
table
chdef -t network net40 net=40.0.0.0 mask=255.0.0.0
Define attributes in the nics
table
Compute node
cn1
has two physical NICs:eth2
andeth3
chdef cn1 nictypes.eth2=ethernet nictypes.eth3=ethernet
Define
bond0
and bondeth2
andeth3
asbond0
chdef cn1 nictypes.bond0=bond nicdevices.bond0="eth2|eth3"
Define VLAN
bond0.1
based onbond0
chdef cn1 nicips.bond0.1=40.0.0.1 nictypes.bond0.1=vlan
Define
nicnetworks
forbond0.1
chdef cn1 nicnetworks.bond0.1=net40
Define
nichostnamesuffixes
forbond0.1
in casemakehosts
to update/etc/hosts
, since the value fornichostnamesuffixes
cannot contain “.”, other characters are recommended instead of “.”, like following:chdef cn1 nichostnamesuffixes.bond0.1=-bond0-1
Enable confignetwork
to configure bridge
If adding
confignetwork
into the node’s postscripts list,confignetwork
will be executed during OS deployment on compute nodechdef cn1 -p postscripts=confignetwork
Or if the compute node is already running, use
updatenode
command to runconfignetwork
postscriptupdatenode cn1 -P confignetwork
Verify VLAN
Login to compute node cn1 and check ifcfg-bond0.1
under /etc/sysconfig/network-scripts/
DEVICE="bond0.1"
BOOTPROTO="static"
IPADDR="40.0.0.1"
NETMASK="255.0.0.0"
NAME="bond0.1"
ONBOOT="yes"
USERCTL=no
VLAN=yes
Use ip addr
command to check if br0
and bond0
are correct.
