we would like setup VLAN on CENTOS 5.X and 4.x. Only VLAN will active, but
primary LAN NOT active. E.g "eth0" inactive, but "eth0.2"
active.
I have been tried several ways, but never successful.
Any ideal?

If it does, it would be for the 'native' (untagged) vlan. -- Les Mikesell lesmikesell at gmail.com

There is no addressing on the 'default' VLAN: ifcfg-eth1: # Intel Corporation 82557/8/9/0/1 Ethernet Pro 100 DEVICE=eth1 BOOTPROTO=none HWADDR=00:50:8B:A5:17:0B IPV6INIT=yes IPV6_AUTOCONF=no ONBOOT=yes DHCP_HOSTNAME=xxx.htt-consult.com VLAN=yes Whereas ifcfg-eth1.11: # Intel Corporation 82557/8/9/0/1 Ethernet Pro 100 DEVICE=eth1.11 BOOTPROTO=none IPV6INIT=yes IPV6_AUTOCONF=no ONBOOT=yes VLAN=yes IPV6ADDR="nnnn:nnnn:3:0::180"
