 You then refresh the DNS server by running /usr/testbed/sbin/named_setup.

 For example, on mini-isi.deterlab.net we have our switch that we will name hp1 at 192.168.254.1 on the HARDWARE_CONTROL network.  So we add it to DNS as follows:

 === Adding in your switches to the database ===
 
+Using the hostname you have given your switch, insert a line in the the nodes table in the database.  If you are adding a dedicated control network switch, use '''ctrlswitch''' as the role.  Otherwise, the role is '''testswitch'''.

 {{{
-insert into nodes set

+=== Setting up Switch Stacks ===
+
+The idea of switch stacks comes from sites that run separate control and experimental networks.  In this scenario, it does not make sense to create experimental vlans on switches that function only as control network switches and vice versa.  The typical DETER deployment scenario will be a switch that handles both.  In this case, we add the same switch to the two different stacks ('Experiment' and 'Control').  We also make sure that is_primary is set to 1 for the Experimental stack line and 0 for the Control stack line (I assume so that we only try creating vlans once per switch).
+
+So in our mini-isi example, we need to add in two entries for our switch hp1:
+
+{{{
+insert into switch_stacks (node_id,stack_id,is_primary) 
+values 
+('hp1','Experiment',1),
+('hp1','Control',0);
+}}}
