peter,
thank you so much for your response
i have bridge-util installed:
bridge-utils-1.1-2
though i do not see any bridge_ports command. is that supposed to be a command
available if i have this package installed?
also, xen network-bridge script works fine and guest network works fine. so i
am still lost.
[jshen@eduout3-host ~]$ rpm -ql bridge-utils-1.1-2
/usr/sbin/brctl

You probably need to install "bridge utils" (a package called
"bridge-utils-<ver>.i386.rpm").
