The Distro CLI getip and ssh commands make a best-effort attempt to determine an IP for the given switch based on its MAC address and then either return that IP or directly ssh to it. It does so by connecting to the Distro Infra container and checking on the configured interface for pre-existing IP neighbor/ARP entries. If no such entries are found it will attempt a subnet ping to refresh the Linux kernel neighbor entries. In most cases this is sufficient after the system has PXE booted and therefore the neighbor cache is filled. Testing is as easy as starting the Distro Infra container: ``` $ ./distro_infra.sh --intf eth1 --persist-dir data ``` Then running the fboss-image device getip command with the appropriate MAC address: ``` $ ./fboss-image device dc:da:4d:fc:ad:2d getip [0.00s] Getting IP for device dc:da:4d:fc:ad:2d 10.250.33.2 ```
The fboss-image device image command configures the Distro Infrastructure to PXE boot the given image file for the given device on the next reboot. This replaces the manual steps previously necessary with the MVP Distro Infrastucture. Testing: ``` $ ./fboss-image device dc:da:4d:fc:ad:2d image nh-fboss-broadcom-xgs.tar [0.00s] Setting image for device dc:da:4d:fc:ad:2d: nh-fboss-broadcom-xgs.tar [0.07s] Using persistent directory: /home/travisb/work/upstream/fboss/fboss-image/distro_infra/data [0.07s] Extracting image tarball to /home/travisb/work/upstream/fboss/fboss-image/distro_infra/data/dc-da-4d-fc-ad-2d...

The fboss-image device image command configures the Distro
Infrastructure to PXE boot the given image file for the given device
on the next reboot.
This replaces the manual steps previously necessary with the MVP
Distro Infrastructure.
