IP aliases + VLANs, how to stack?
 
I know how to create an alias, I know how to create a VLAN device, but how can I create aliases on VLANs, or VLANs on aliases? I tried vconfig on eth0:0, which failed. I tried to ifconfig eth0.111:0, which also failed. Anyone know how the heck you're supposed to configure multiple addresses on the same VLAN on the same physical interface???

if using RHEL/Clones ifcfg-eth0.901:0 works. Contents as follows

Code:
DEVICE=eth0.901:0
BOOTPROTO=static
IPADDR=xx.xx.xx.xx
NETMASK=255.255.255.0
ONBOOT=yes
VLAN=yes
On debian.
Code:
auto vlan901:0
iface vlan901:0 inet static
        address xx.xx.xx.xx
        netmask 255.255.255.0

I tried that on CentOS 4.6 and it didn't work. Hmmmm. What version of Red Hat did you test it on?

I am using that on centos 5.x, i do not think the initscripts package on 4.x supports it looking at the change log support for vlan aliases was added on Fri Jul 28 03:56:50 2006

Figures :\

Well thanks for the info, that's exactly what I needed. I thought it should work like you described (which is the first thing I tried last week), so I was very surprised when it didn't.
