Hi Srini,
I'm sorry, the previous email was wrong title, so I email to this archive
and you again.
Here is my system version just like the following:
-------------------Version----
--------------------
CentOS 5.4
Kernel version 2.6.31.14
NetFPGA 2.2.0
OpenFlow 1.0.0
openflow_switch.bit 1.0.3 (from netfpga/bitfiles/)
NOX Controller NOX 0.9.0(zaku)~full~beta
----------------------------------------------------
Here is my answers for your questions:
1) Before I added Vlan action, I was very sure that pyswitch worked
normally, Because
I had used dpctl to check the flow table after OpenFlow switch connected
to NOX controller.
2) I set two notebooks connect to OpenFlow Switch, and I just ping between
the two notebooks.
3) NOX Controller NOX 0.9.0(zaku)~full~beta
4) Please see the attachment
5) Please see the following:
