So you implemented gratuitous ARP here? GARP?

@pavel-shirshov Yes. Because after the neighbor is created, all the traffic goes through data plane and no packets will be received from the CPU. Thus after certain time the neighbor will be updated to stale state. This is one reference describing similar issue here.

@stcheng stcheng force-pushed the master branch 2 times, most recently from b9ca7e2 to 42ae02b Compare March 22, 2017 20:29

suggest follow Joe's pattern:

  1. /usr/bin/start.sh is the only section autostart
  2. /usr/bin/start.sh will start all other sections, so the order is guaranteed

echo will fail in virtual switch since /sys directory is read-only.
need to use ip command to setup the vlan_filtering which is not available in debian 8.
Once we move sonic to debian 9, we can use IP command by default.
