VLAN Tagging and Vanity Naming in Solaris 11

While awaiting Solaris 11 to be released, I've recently been poking
around in Solaris 11 Express for a preview of what to expect.  In setting
up a test box, I needed to set up VLAN tagging (802.1q trunking) on
an interface.  Due to some of the new Solaris 11 networking features,

Host Info - Network Interfaces

As part of the 'host info' series, we're on to network interfaces.
I know, can't be too hard, run 'ifconfig'.  That's fine if you want IP
(layer 3) related information, but what about layer 2 details?  To get
link status, associated interface speed, duplex, and VLAN tagging

VLAN Tagged Interfaces (Linux)

A while back, I wrote on how to setup VLAN tagged interfaces on Solaris
and FreeBSD.  Though I've also needed to set them up under Linux, I
never seemed to get around to writing up how to do so.  To remedy this,
the following are our setup details:

IPMP and 802.1q on Linux

Described herein is the practice of using IPMP (IP MultiPathing) and VLAN
tagged (802.1q trunking) interfaces layered together for the purpose of
port considerations (read: consolidation) and HA (high availability).
The following points should be noted relevant to the host used in the

VLAN Tagged Interfaces (FreeBSD)

In order to make use of VLAN tagged interfaces in FreeBSD, kernel support
must be added, thus requiring a rebuild of the kernel.  Also, you must
have an interface capable of handling VLAN tagging (can be determined
by the man page of the interface driver, ex: man bge).  Kernel support

VLAN Tagged Interfaces (Solaris)

In order to use VLAN tagged interfaces in Solaris, one simply needs to
have an interface capable of handling VLAN tagging (can be determined by
the man page of the interface driver, ex: man bge, as well as man dladm).
Providing an interface supportive of VLAN tagging, one may configure the
