I have tried using "self.logger.debug" to print messages inside the
following functions.
1) ryu/topology/api.py
- get_all_switch()
https://github.com/karthik82/ryu/blob/master/ryu/topology/api.py#L27
- get_all_link()
https://github.com/karthik82/ryu/blob/master/ryu/topology/api.py#L38
2) ryu/topology/switches.py
- switch_request_handler()
https://github.com/karthik82/ryu/blob/master/ryu/topology/switches.py#L840
- link_request_handler()
https://github.com/karthik82/ryu/blob/master/ryu/topology/switches.py#L856
As per my understanding switch_request_handler() and link_request_handler()
handles the messages *EventLinkRequest* and *EventSwitchRequest *sent by
(1)
I am calling
- get_all_switch()
- get_all_link()
from
https://github.com/karthik82/ryu/blob/master/ryu/app/simple_switch.py#L53
and
https://github.com/karthik82/ryu/blob/master/ryu/app/simple_switch.py#L57
from packet_in handler of simple_switch.py
My question is
I *CAN *see debug messages from *get_all_switch()* and *get_all_link()*
I *CANNOT* see debug messages from *switch_request_handler() *and
*link_request_handler()
- WHY???*
Below I can see get_all_switch - sending EventSwitchRequest()
get_all_link - sending EventLinkRequest()
But I *CANNOT * see debug messages from *switch_request_handler()* and
*link_request_handler()*
*Partial trace.*
get_all_switch
EVENT SimpleSwitch->switches EventSwitchRequest
get_all_link
EVENT SimpleSwitch->switches EventLinkRequest
EVENT ofp_event->switches EventOFPPacketIn
EVENT ofp_event->SimpleSwitch EventOFPPacketIn
get_all_switch
EVENT SimpleSwitch->switches EventSwitchRequest
get_all_link
EVENT SimpleSwitch->switches EventLinkRequest
It would be great if you could answer this question
Thanks & Regards,
Karthik.
