+This is the root switch to the Orbit network.That also includes firewall and Internal switch ports.  
+
+== Legacy switch layout == 
+
+VLAN 50 is the publicly exposed VLAN - 4 ports (DMZ, 2 planet lab, firewall out)
+VLAN 1001-1005 - Cisco associated (ignore)
+9,10- not used 
+
+ports can be divided up into 3 groups
+
+ 1. Infrastructure - Not really visible to user - Aruba, Internal, Instrumental ect - VLANs 1-6  
+ 2. Experimental - Pertains to Grid, outdoor, Sandboxes - VLANs 7,8,11-38
+ 3. Public - Visible from outside - VLAN 50
+
+== IP8800 sw-top layout ==
+
+We want to combine the internal, firewall feed, and top switch port configs onto one NEC IP8800. The ports that comprise this  setup are:
+
+ 1. 4 VLAN 50 ports (ports 1-4)
+ 1. 4 firewall ports (only 3 actually needed to go into ASA)
+ 1. 10 Internal (VLAN 2) Ports
+ 1. 16 Top switch ports (Assorted, originally 20 including 4 VLAN 50 ports)

+
+=== Creating VLANs ===
+
+< A table of the vlans coming up soon. > 
+
+=== Associating VLANs with ports ===
+
+Now that you have properly named VLANs, you can associate them with ports. 
+
+<<here will be the diagram of the switchports layout of the configs.>>
+
+first, the 4 publically visible VLAN 50 ports:
+{{{
+(config)# int range gi 0/1-4
+(config-if-range)# switchport access vlan 50
+}}}
+
+Then, the firewall ports feeding the VLANs into the ASA; These are specialized trunk ports:
+
+ * geth0/7 - VLAN 50
+ * geth0/8 - VLANs 1-6
+ * geth0/9 - VLANs 7,8
+ * geth0/10 - VLANs 11-38
+
+The commands to make this happen are the following. First make four ports into trunk ports using the 'interface range' context:
+{{{
+(config)# int ran gi 0/7-10
+(config-if-range)# sw mo tru
+!(config-if-range)#
+}}}
+
+Then, specify allowed VLANs for each port. This is according to the list above. 
+{{{
+!(config-if-range)# ##geth0/7 - VLAN 50##
+!(config-if-range)# interface gigabitethernet 0/7
+!(config-if)# swi trunk allowed vlan 50 
+!(config-if)# ##geth0/8 - VLANs 1-6##
+!(config-if)# interface gi 0/8
+!(config-if)# swi trunk allow vlan 1-6
+!(config-if)# ##geth0/9 - VLANs 7,8##
+!(config-if)# interface gi 0/9
+!(config-if)# swi tru all vl 7,8
+!(config-if)# ##geth0/10 - VLANs 11-37##
+!(config-if)# interface gi 0/10
+!(config-if)# swi tru all vl 11-38
+!(config-if)# save
+(config-if)# exit
+}}}
+
+the configuration results:
+{{{
+(config)# int ran gi 0/7-10
+(config-if-range)# sh
+interface gigabitethernet 0/7
+  switchport mode trunk
+  switchport trunk allowed vlan 50
+!
+interface gigabitethernet 0/8
+  switchport mode trunk
+  switchport trunk allowed vlan 1-6
+!
+interface gigabitethernet 0/9
+  switchport mode trunk
+  switchport trunk allowed vlan 7-8
+!
+interface gigabitethernet 0/10
+  switchport mode trunk
+  switchport trunk allowed vlan 11-38
+!
+}}}
+
+Next, the 10 Internal ports; These are regular switchports all associated to VLAN 2.
+{{{
+(config)# int ran gi 0/13-22
+(config-if-range)# sw mo dot1q-tunnel 
+!(config-if-range)# sw acc vlan 2
+}}}
+
+Finally, the sw_top configurations; This is perhaps the most complicated part. the ports will be configured from 0/48 to leave ample space between the Internal ports and these ports, which are all specialized trunk ports (we won't want people to accidentally be able to plug into them!).
