sw-sb-01 (Aggregate SandBox Switch 1)

sw-sb-01 is a replacement for legacy sandbox switches for sb 1,2,5,6,7, and 8.

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.
