sw-sb-01 (Aggregate SandBox Switch 1)
sw-sb-01 is a replacement for legacy sandbox switches for sb 1,2,5,7, and 8. It also includes Aruba VLAN (4) ports.
Access : 172.16.0.253
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. As an OpenFlow switch, we also need a dedicated port to connect the switch to a controller. 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)
- OpenFlow control VLANs: 2 (to controller - two to make things tidy)
- Trunk: 4 (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 |
In addition, VLAN 100 is the defacto VLAN for the !OpenFLow control channel at WINLAB.

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
Each VLAN is its own virtual switch. The following is the contents of openflow.conf.
