Configure Bridge 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
br0
based onbond0
Assign ip
40.0.0.1
to the bridge interfacebr0
Add network object into the networks table
Add/modify network data 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
br0
based onbond0
chdef cn1 nicips.br0=40.0.0.1 nictypes.br0=bridge
Define
nicnetworks
forbr0
chdef cn1 nicnetworks.br0=net40
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 bridge
Login to compute node cn1 and check bonding options in /etc/sysconfig/network-scripts/ifcfg-bond0
file
DEVICE="bond0"
BOOTPROTO="none"
NAME="bond0"
BONDING_MASTER="yes"
ONBOOT="yes"
USERCTL="no"
TYPE="Bond"
BONDING_OPTS="mode=802.3ad miimon=100"
DHCLIENTARGS="-timeout 200"
BRIDGE=br0
Check ifcfg-br0
under /etc/sysconfig/network-scripts/
DEVICE="br0"
BOOTPROTO="static"
IPADDR="40.0.0.1"
NETMASK="255.0.0.0"
NAME="br0"
ONBOOT="yes"
STP="on"
TYPE="Bridge"
Use ip addr
command to check if br0
and bond0
are correct.
