We have one of these nice new and fancy Cisco ASR920-24SZ, just realized it doesn't have an RJ45 Console port only USB. When we deploy devices at our pop we wire the console port to a terminal\console server, well that doesn't work for a usb console device. So what is everyone doing for out of band management via the console when it's a usb only device? Is there something I am missing?
Likely not. I've seen most equipment makers start to ignore serial console. The default these appears to be moving to a uBoot/PXE style network setup where you push an image and such via TFTP/DHCP into the device.
Is there a console server for USB?
I've not seen one show up, but there are other devices like this which the DIY industry has started to build: http://freetserv.github.io/ I have a side business i'm tinkering with and these are open source hardware. If there is interest, I'd be willing to build these in volume and drive the cost down. It would not be difficult to do a giant USB hub that was similar.
Does cisco make an USB to RJ45 Jack adapter?
Yes, but I'm always concerned about what boot messages are lost or things you can't quite do properly (like send break, etc) to get into the device as you're waiting for the USB to initalize, driver to present to OS, etc.. Maybe they spent more time thinking about this than I am aware, but it's something I've not had a proper solution explained to me for. - Jared -- Jared Mauch | pgp key available via finger from jared () puck nether net clue++; | http://puck.nether.net/~jared/ My statements are only mine.
