= The Aggregate SandBox Switch = 
The aggregate sandbox switch is a replacement for legacy sandbox switches for sb 1,2,5,6,7, and 8. Therefore it encompasses the VLANs required for all 6 testbeds to function.  
 
== Testbed switch layout ==
Each testbed requires 2 ports each for CM, Control, and Data links for the nodes, a Control VLAN link to the Console, and a trunk link to the top switch. In the aggregate switch ports are allocated in the following numbers:
 * CM: 12 ports (2 per !SandBox)
 * Control: 18 ports - 12 for nodes, + 6 for Console links
 * Data: 12 (as with CM)
 * Trunk: 6 (leftover)   

== VLANs ==
VLAN 3 (CM) is consistent across all !SandBoxes. Each sb has its own Control and Data VLANs as such:
||Testbed||Control VLAN||Data VLAN||
||sb1||11||12||
||sb2||13||14||
||sb5||19||20||
||sb6||21||22||
||sb7||23||24||
||sb8||25||26|| 
 
== Port Assignments ==
The final port VLAN assignments:

||Port(s)||VLAN(s)||Description||
||0/1-12||3||CM||
||Control-to nodes        ||
||0/13,14||11||sb1_ctrl||
||0/15,16||13||sb2_ctrl||
||0/17,18||19||sb5_ctrl||
||0/19,20||21||sb6_ctrl||
||0/21,22||23||sb7_ctrl||
||0/23,24||25||sb8_ctrl||
||Control-to Consoles     ||
||0/25||11||sb1_ctrl||
||0/26||13||sb2_ctrl||
||0/27||19||sb5_ctrl||
||0/28||21||sb6_ctrl||
||0/29||23||sb7_ctrl||
||0/30||25||sb8_ctrl||
||Data ||
||0/31,32||12||sb1_data||
||0/33,34||14||sb2_data||
||0/35,36||20||sb5_data||
||0/37,38||22||sb6_data||
||0/39,40||24||sb7_data||
||0/41,42||26||sb8_data||
||0/43-48||3,11-14,19-26||Trunk||

== Legacy Configurations ==
All forms of spanning tree (STP, PVST+) are disabled for compliance with !OpenFlow and Node-handler/Agent services. From configuration mode:
{{{
spanning-tree disable
no spanning-tree vlan 1,3,11-14,19-26
}}} 

vlans are named from the `vlan` context. 

Interface-range contexts are used for batch configuration of similar ports. Below is the configuration of the CM and SB1 Control VLAN ports: 
{{{
!(config)# interface range gi 0/1-12
!(config-if-range)# switchport access vlan 3
!(config-if-range)# interface range gi 0/13-14   
!(config-if-range)# sw acc vlan 11 
}}}

Similarly, the trunk ports:
{{{
interface range gi 0/43-48
switchport mode trunk
switchport trunk allowed vlan 3,11-14,19-26
switchport trunk native vlan 1
}}}

== !OpenFlow configurations ==
To be added.
