= sw-sb-01 (The Aggregate SandBox Switch) = sw-sb-01 is a replacement for legacy sandbox switches for sb 1,2,5,6,7, and 8. '''Access :''' 172.16.0.221 == 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. == 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|| ||0/47||1-3,11-14,19-26||OF control|| ||0/43-46,48||1,3,11-14,19-26||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 == Each VLAN is its own virtual switch. The following is the contents of openflow.conf. {{{ setvsi 3 1-12 tcp 172.16.0.4:6633 dpid 0x0129834756ab setvsi 11 13,14,25 tcp 172.16.0.4:6633 dpid 0x012983475611 setvsi 13 15,16,26 tcp 172.16.0.4:6633 dpid 0x012983475613 setvsi 19 17,18,27 tcp 172.16.0.4:6633 dpid 0x012983475615 setvsi 21 19,20,28 tcp 172.16.0.4:6633 dpid 0x012983475621 setvsi 23 21,22,29 tcp 172.16.0.4:6633 dpid 0x012983475623 setvsi 25 23,24,30 tcp 172.16.0.4:6633 dpid 0x012983475625 setvsi 12 31,32 tcp 172.16.0.4:6633 dpid 0x012983475612 setvsi 14 33,34 tcp 172.16.0.4:6633 dpid 0x012983475614 setvsi 20 35,36 tcp 172.16.0.4:6633 dpid 0x012983475620 setvsi 22 37,38 tcp 172.16.0.4:6633 dpid 0x012983475622 setvsi 24 39,40 tcp 172.16.0.4:6633 dpid 0x012983475624 setvsi 26 41,42 tcp 172.16.0.4:6633 dpid 0x012983475626 }}}
