 Description   

We are trying to configure switch-idle-timeout to 1000ms in openflowplugin configuration for quick switch failure detection if the switch is being shut down forcefully.
After changing the configuration, we sometimes experience TCP disconnect from the controller side during handshake phase.

Quick switch failure detection is a crucial feature for production deployments.

See more info in https://lists.opendaylight.org/pipermail/openflowjava-dev/2015-April/000464.html
Is there a way to let the handshake process timeout and ignore switch-idle-timeout during handshake?

Hi Michal,

Any thoughts? There is a comment by Michal Rehak in the email referenced.

Thanks,

Hi,
there are 2 solutions i can think of right now:

  • provide 2 configurable timeout limits - for HANDSHAKING and for WORKING state (and maybe for echo reply limit as well)
  • expose rpc for disconnecting device

Both require API change.

No response for a long time. I checked this and this is related to the He design. This should be checked with the latest code and if needed reopen this.
