* Can I make USB IP addresses persist across unplug-replug events. @ 2014-04-04 13:47 David Laight 2014-04-04 14:08 ` Antonio Quartulli 0 siblings, 1 reply; 2+ messages in thread From: David Laight @ 2014-04-04 13:47 UTC (permalink / raw) To: netdev@vger.kernel.org Is there a sane way to stop the local IP address (etc) associated with a USB network interface being deleted when the USB card is unplugged - so that everything will recover quickly when it is plugged back in? Maybe something horrid like master-slave bonding/teaming with a dummy software interface which will silently discard tx traffic when the usb interface is missing.

What about a bridge interface? When the usb network device is plugged-in you can enslave it in the bridge (and viceversa on unplug). The IP is configured on the bridge so it will survive and also the users applications using it. no? or am I missing something important? :) Cheers, -- Antonio Quartulli [-- Attachment #2: OpenPGP digital signature --] [-- Type: application/pgp-signature, Size: 901 bytes --] ^ permalink raw reply [flat|nested] 2+ messages in thread
