    While that is a very common use case (bootp), I’ve ran across a lot of hardware that use it for config upload and download:

    • To upload a config to an industrial grade Garettcom switch you need to use tftp. Same goes for firmware updates and config backups.

    • This Cisco phone I was battling with once tried to download a config vea TFTP feom its DHCP server, assuming its DHCP server was part of the SIP infrastructure. The above mechanism was also used successfully by some other proprietary hardware built inhouse for firmware updates.

    In the same rack as the router we usually have two 48P PoE switches in a stack8ng configuration. Depending on the scale of the setup, we often have the same type of switches elsewhere, trunked in via 10gig fber. On rare occasions we have a bunch of extra fibers for which we use Aruba 3810 with only SFP ports.

    We also have 100gig in use, but that’s only for a few closed off networks between the servers, with its dedicated Mellanox switch. While they do connect to the 10gig network via a breakout cable, the 100gig bandwidth is only needed internally in the cluster.
