Hello,
I’m trying to configure a CentOS 7 server to act as a host for a bunch of virtual servers (KVM). I have an 802.3ad bonded Ethernet connected to the server with a bunch of tagged VLANs. I want to be able to build a bridge interface on the server for each VLAN and then attach that to the bond interface and the virtual clients. I also want to attach a host interface to one of the VLANs for access to the host from my Infrastructure network.
I have everything working but the host interface, What device do I put into ifcfg-VLAN-OOB to create a new software only interface.
Here is what I have so far.
EM1-4 are configured as slaves to BOND0
ifcfg-em1:
TYPE=Ethernet
USERSTL=no
MASTER=bond0
NAME=em1
UUID=0ca45a64-70eb-4bfb-bf73-90b221d5fa65
DEVICE=em1
ONBOOT=yes
SLAVE=yes
ifcfg-em2:
TYPE=Ethernet
NAME=em2
UUID=d79cc76a-8f38-460c-9430-2ae78b43dc1d
DEVICE=em2
ONBOOT=yes
MASTER=bond0
USERCTL=no
SLAVE=yes
ifcfg-em3:
TYPE=Ethernet
NAME=em3
UUID=9f7cf127-eba2-45e8-95bd-814e6066aa74
DEVICE=em3
ONBOOT=yes
MASTER=bond0
USERCTL=no
SLAVE=yes
ifcfg-em4
TYPE=Ethernet
NAME=em4
UUID=53517fa5-9e22-4286-a367-8c91ef6f1883
DEVICE=em4
ONBOOT=yes
MASTER=bond0
USERCTL=no
SLAVE=yes
ifcfg-bond0:
DEVICE=bond0
NAME=bond0
TYPE=bond
BONDING_MASTER=yes
ONBOOT=yes
BONDING_OPTS="mode=802.3ad miimon=10 lacp_rate=1"
USERCTL=no
Bond0 is up, the switch & server are happy all 4 links are live, no errors
I created a new bridge:
ifcfg-br0:
DEVICE=br1
TYPE=BRIDGE
ONBOOT=yes
NAME=br1
I created a VLAN interface on bond0 and attached it to the bridge
ifcfg-bond0.77:
DEVICE=bond0.77
BOOTPROTO=none
ONBOOT=yes
VLAN=yes
TYPE=Vlan
PHYSDEV=bond0
VLAN_ID=77
NAME="Vlan bond0.77"
BRIDGE=br1
UUID=d91d518a-cf03-555f-9837-ef2d2763218b
Now,
How do I create a new interface ‘VLAN-OOB’, attach it to the bridge and assign an IP address?
ifcfg-VLAN-OOB:
DEVICE=????????
BOOTPROTO=none
ONBOOT=yes
NETWORK=10.126.77.0
IPADDR=10.126.77.2
PREFIX=24
GATEWAY=10.126.77.1
DNS1=66.59.48.85
DNS2=66.59.48.86
DOMAIN=crocker.com
DEFROUTE=yes
NAME=“OOB Management VLAN"
BRIDGE=br1
I want to be able to attach virtual-client interfaces to br1 so they can be on the same network. Eventually I’ll have a dozen bridges with different networks (Internet, VOIP, OOB, Backup, etc)
Thanks
-Matt
