Why I did it A race condition exists while the TPH is processing a netlink message - if a second netlink message arrives during processing it will be missed since TPH is not listening for other messages. Another bug was found where TPH was unnecessarily restarting since it was checking admin status instead of operational status of portchannels. How I did it Subscribe to APPL_DB for updates on LAG operational state Track currently sniffed interfaces How to verify it Send tunnel packets with destination IP of an unresolved neighbor, verify that ping commands are run Shut down a portchannel interface, verify that sniffer does not restart Send tunnel packets, verify ping commands are still run Bring up portchannel interface, verify that sniffer restarts Signed-off-by: Lawrence Lee <lawlee@microsoft.com>
