Dear all, I have a problem in discovering links with HP procurve switch. When I run discovery module, it cannot discover links to procurve switch.
Below is the screen output when I run NOX with pyswitch and discovery. $ ./nox_core -i ptcp:6633 pyswitch discovery NOX 0.9.0(zaku)~full~beta (nox_core), compiled Sep 7 2011 21:42:33 Compiled with OpenFlow 0x01 00001|discovery|WARN:[0x12101L:2]new link detected (00:00:00:00:00:01:21:01 p:2 -> 00:00:00:00:00:01:22:01 p:2) 00002|discovery|WARN:[0xa90c0913435ef00L:26]new link detected (0a:90:c0:91:34:35:ef:00 p:26 -> 00:00:00:00:00:01:21:01 p:1) 00003|discovery|WARN:[0x12201L:2]new link detected (00:00:00:00:00:01:22:01 p:2 -> 00:00:00:00:00:01:21:01 p:2) NOX discovers only uni-directional link from Procurve (0xa90c0913435ef00L) to OpenvSwitch (0x12101L). I followed instructions in http://www.openflow.org/wk/index.php/Configuring_HP_Procurve and disable LLDP. But it doesn't make any difference. The firmware version of procurve switch is K.14.68o. # show version Image stamp: /sw/code/build/btm(jeant_openflow) Aug 17 2010 17:47:11 K.14.68o 66 And for other OpenFlow-enabled switches, I use OpenvSwitch. # ovs-openflowd -V ovs-openflowd (Open vSwitch) 1.1.0pre2 Compiled Jul 14 2011 21:30:55 OpenFlow versions 0x1:0x1 I would appreciate any comments. Regards, - Namgon
