H5G SDN Demo

tag: H5G, SDN

Nemo testbed subnet 192.168.124.1 (H5Gbackend).

netgear mgmt port 9 has IP 192.168.124.115 user admin pwd empty.

netgear port 15-16 dhcp for 2 test hosts.

Test hosts connected over switch with static IP

• controller centos 7
  • user admin pwd a1d3m7
  • Lanport: 192.168.0.113
  • Usb lan port: 192.168.124.119 (H5G backend)

• compute centos 7
  • user admin pwd a1d3m7
  • Lanport: 192.168.0.114
  • Usb lan port: 192.168.124.118 (H5G backend)

Port 9 is the defaul mgmt port with dhcp. OOB doesn't get dhcp until reconfigure and reboot :(. Seems like only mgmt iface get activated. OOB will be configured first.

Use usb console cable + minicom.

Enable mode

  enable
  password: admin (must be set in webUI, after each restart? O.o).
 
  

Physical connections

• Connect the Out of Band (OOB) port to the SDN Controllers LAN.
• Connect test computers to two ports on the switch, say 1/0/15 and 1/0/16.

Configure the hostname

(M4300-28G) # hostname TestOF-SW

Configure the OOB “serviceport” on the M4300

Note that this is done at the EXEC level and not the “configure” level

(OF-SW) # enable 

(OF-SW) # serviceport protocol none
(OF-SW) # serviceport ip 192.168.1.100 255.255.255.0 192.168.1.1
(OF-SW) # serviceport ipv6 address 2a92:168:1::100/48
(OF-SW) # serviceport ipv6 gateway 2a98:8:8::1

Configure OpenFlow Note: THe SDN Controller is located on a server 192.168.1.101 on port 6633

(OF-SW) # configure
(OF-SW) (Config) # openflow ip-mode serviceport
(OF-SW) (Config) # openflow controller 192.168.1.101 6633 tcp
(OF-SW) (Config) # openflow variant openflow13
