[TriLUG] tagging vlans with Red Hat /CentOS

[Chris Bullock]

I am starting to play with vmware and I need to tag the port that my
vmware box is connected to on the lan so that the vmware physical
interface is a member of all associated vlans, but I have not gotten it to
successfully work, so I want to narrow my search to 1 the switch, 2 the
os, 3 the nic of the server.
I followed this kb article on red hats web site:
http://kbase.redhat.com/faq/FAQ_45_3681.shtm

When I tag the port on the switch, I lose all my networking to that host,
even after restarting the network.  Here is my eth0 config:
[cgb at apollo ~]$ sudo cat /etc/sysconfig/network-scripts/ifcfg-eth0*
DEVICE=eth0
ONBOOT=yes

DEVICE=eth0.4
BOOTPROTO=static
HWADDR=00:08:02:DF:89:4A
IPADDR=172.24.4.243
NETMASK=255.255.252.0
NETWORK=172.24.4.0
GATEWAY=172.24.4.1
ONBOOT=yes
TYPE=Ethernet
VLAN=yes

Here is the outcome of ifconfig:
[cgb at apollo ~]$ /sbin/ifconfig
eth0      Link encap:Ethernet  HWaddr 00:08:02:DF:89:4A
          inet addr:172.24.4.241  Bcast:172.24.7.255  Mask:255.255.252.0
          inet6 addr: fe80::208:2ff:fedf:894a/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:7163372 errors:0 dropped:0 overruns:0 frame:0
          TX packets:8645697 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:819521529 (781.5 MiB)  TX bytes:3667339610 (3.4 GiB)

eth0.4    Link encap:Ethernet  HWaddr 00:08:02:DF:89:4A
          inet addr:172.24.4.243  Bcast:172.24.7.255  Mask:255.255.252.0
          inet6 addr: fe80::208:2ff:fedf:894a/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:0 errors:0 dropped:0 overruns:0 frame:0
          TX packets:11 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0
          RX bytes:0 (0.0 b)  TX bytes:674 (674.0 b)


My question here is where in the world is it pulling the IP address for
eth0?

Here is some of the dmesg with eth0 in it:
bridge-eth0: enabling the bridge
bridge-eth0: enabled promiscuous mode
bridge-eth0: up
e100: eth0: e100_watchdog: link up, 100Mbps, full-duplex
divert: allocating divert_blk for eth0.4
eth0.4: add 33:33:00:00:00:01 mcast address to master interface
eth0.4: add 33:33:ff:df:89:4a mcast address to master interface
eth0.4: add 01:00:5e:00:00:01 mcast address to master interface
eth0: no IPv6 routers present
eth0.4: no IPv6 routers present
[cgb at apollo ~]$ 
Any help would be appreciated.
