Internal/OpenFlow/Notes
v26 v27 1 1 = Notes = 2 2 This section covers discussions and some background work that went into this project. 3 4 == Overview ==5 The things covered here are:6 7 * DHCP relay agents8 * VLANS9 * Trunking10 3 11 4 … … 337 330 === 9/15 === 338 331 339 * ca - quiz on friday (non-sequitor)340 * meeting at 2 - try to get out of work.341 332 * group acl on switches : ok 342 333 * update perl-Net libraries on centOS … … 358 349 * Reinstall NetFPGA !OpenFlow software 359 350 * Move NetFPGA to new chassis 360 * CA Ch2 361 * probability/ DSPD 362 351 363 352 == NetFPGA lives! 10/17 == 364 353 The box that was set up by Nithin finally works - it passed the OpenFlow switch regression test. … … 366 355 The other box has a compromised NIC - the network does not work if the machine is started up while connected to the LAN, however it functions if it is connected after start-up. The on-board NIC is incompatible with drivers that come with CentOS 5.2; as a standby solution, another NIC has been slapped on for the net-install, after which I will try to update the drivers. 367 356 357 == L2TP SUCCESS!!!! 10/29 == 358 359 The setup process was actually not so pain full. We only needed 2 packages ''vtun'' and ''bridge-utils''. We copied the config files almost verbatim from (http://omf.mytestbed.net/wiki/omf/L2HowTo). The only exception being we changed the client address to 10.40.0.251. 360 361 Log messages on both machines seem to indicate success. We'll have to "test" it with some switching sauce. To bring up the br0 interface we need to use ifup (not ifconfig dev up). Note this will fail if ''bridge-utils'' is not installed since the interface is virtual and made by brctl. Once br0 is up, restarting vtun caused many messages to appear in the syslog of landing1 (where our packets go to die). 362 363 == CentOS shinanigans, Ubuntu NetFPGA compatibility. == 364 CentOS proved to ba a difficult beast to deal with when it came to getting it to work with anything. Notably speaking: 365 * CentOS 5.2 realtek NIC driver incompatibility (will give you a great time trying to do the net-install) 366 * NetFPGA drivers do not compile without kernel update (what it uses expects the use of a different kernel version due to dependencies) 367 * Even after the FPGA is working, kernel modules for !OpenFlow switches failing to build properly 368 369 Supposedly, NetFPGAs are capable of working with machines running Ubuntu. hopefully this works. 370 371 * Ubuntu-NetFPGA Compatibility info: http://www.netfpga.org/netfpgawiki/index.php/Ubuntu_Compatibility#NetFPGA_Beta_Changes_.28for_Ubuntu.29 372 373 ---So, the other box is now running Ubuntu 8.04 desktop edition. 374 They seem to have changed a few things around, i.e. run is run.pl, ect. You also need an account to download the NetFPGA base package. 368 375 369 376 [[BR]] … … 373 380 [wiki:Internal/OpenFlow/ return to OpenFlow index] 374 381 375 == L2TP SUCCESS!!!! ==376 377 The setup process was actually not so pain full.
