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
