Is it possible to have a physical interface VLAN'd and the one of those VLAN having an additional virtual IP


Interface Role Type IP Address

Ethernet
eno1 External Static 1.2.3.4
eno2 LAN DHCP
eno3 LAN DHCP
eno4 LAN Static 192.168.0.1

VLAN
eno2.100 LAN Static 10.10.11.5
eno2.200 LAN Static 10.10.9.130
eno2.250 LAN Static 10.10.9.1
eno3.370 LAN Static 192.168.255.214



What I would like to do is add Virtual IP, 10.10.11.1 to eno2.100.

I can't just add it to eno2 as the layer 3 switch rejects the packets. So can I create an eno2.100:1 = 10.10.11.1

    A VLAN ".5" already existed, so let's try an experiment...
    On 'danda' - ClearOS 6.x

    [root@danda ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0.5:0
    DEVICE=eth0.5:0
    TYPE="Virtual"
    ONBOOT="yes"
    USERCTL="no"
    BOOTPROTO="static"
    NO_ALIASROUTING="yes"
    IPADDR="192.168.5.126"
    NETMASK="255.255.255.0"
    [/code
    On 'karien' - ClearOS 7.x
    [code]
    [root@karien ~]# cat /etc/sysconfig/network-scripts/ifcfg-enp4s6f1.5:0
    DEVICE=enp4s6f1.5:0
    TYPE="Virtual"
    ONBOOT="yes"
    USERCTL="no"
    BOOTPROTO="static"
    NO_ALIASROUTING="yes"
    IPADDR="192.168.5.198"
    NETMASK="255.255.255.0"

    respective /etc/clearos/network.conf files updated with the new interface and
    firewalls restarted..
    A ping to the other system was successful either way..

    [root@danda ~]# ping -c 5 192.168.5.198

    File transfer using scp successful

    [root@danda ~]# scp -p dry_run.txt karien:/root/
    dry_run.txt 100% 2414KB 2.4MB/s 00:00

    So that works between two ClearOS systems... All edits by hand - not sure if webconfig would support this
    That's the closest I can get to your request with what exists here...
