Just because they listen on every NIC doesn't mean they will all get
used. We have TSM servers with 4 GB NIC's.  We have 4 TSM instances
on it.  Each one has a seperate Port.  Of course all 4 TSM instances
will respond to requests coming into any of the NIC's. However in our
client dsm.opt files we specify a specific IP when going to the
server.  As a result we ensure our client traffic only uses one GB
NIC for a particular instance.  Further, should that NIC ever go bad
we simply have to update the DNS alias for that NIC to point to a
different one and because all TSM instances listen on all NIC's the
traffic will be easily redirected until the NIC is fixed.

I'd use 803.1q and 802.3ad for this.

Which NIC is used is controlled by what IP's or DNS name you use in
the dsm.opt file.

true, but since the dsm.sys/dsm.opt file (or even the application trying
to connect to the TSM server) might not be under my control...
