Configure Bridge Based on VLAN
The following example set the xCAT properties for compute node cn1
to create:
Compute node
cn1
has one physical NIC: eth0Define 2 vlans: eth0.6 and eth0.7 based on eth0
Define 2 bridge br1 and br2
Assign ip
60.5.106.9
to br1 and70.5.106.9
to br2
Define attributes in the nics
table
Using the
mkdef
orchdef
commandsCompute node
cn1
has one physical NIC:eth0
chdef cn1 nictypes.eth0=ethernet
Define vlan
eth0.6
andeth0.7
based oneth0
chdef cn1 nictypes.eth0.6=vlan nicdevices.eth0.6="eth0" nictypes.eth0.7=vlan nicdevices.eth0.7="eth0"
Define bridge
br1
andbr2
chdef cn1 nicips.br1=60.5.106.9 nicips.br2=70.5.106.9 nictypes.br1=bridge nictypes.br2=bridge
Add network object into the networks table
Use the chdef
command to add/modify the networks in the networks
table
chdef -t network net60 net=60.0.0.0 mask=255.0.0.0
chdef -t network net70 net=70.0.0.0 mask=255.0.0.0
chdef cn1 nicnetworks.br1=net60 nicnetworks.br2=net70
Add confignetwork
into the node’s postscripts list
Use command below to add confignetwork
into the node’s postscripts list
chdef cn1 -p postscripts=confignetwork
During OS deployment on compute node, confignetwork
postscript will be executed.
If the compute node is already running, use updatenode
command to run confignetwork
postscript without rebooting the node:
updatenode cn1 -P confignetwork
Verify Bridge
Login to compute node cn1 and check ifcfg-br1
and ifcfg-br2
under /etc/sysconfig/network-scripts/
like
BOOTPROTO="static"
IPADDR="60.5.106.9"
NETMASK="255.0.0.0"
NAME="br1"
ONBOOT="yes"
STP="on"
TYPE="Bridge"
Use ip addr
command to check if br1
, br2
, eth0.6
and eth0.7
.
