"COMING SOON: Security features, such as SSL and SNMPv3"

"Creates systems redundancy and increases security"
unless you consider ssl and snmpv3 security relevant I guess? Also of interest:
"10/100 Mb switched Ethernet" I hope your local-in-pop switch gear
has 10/100/1000 and not just 1000 ports. This may be more problematic
as the future progresses... (you can't get 100mbps ports on a qfx if I
recall correctly, for example)
However I would like to limit the amount of equipment we deploy at a pop, the
majority of our pop's don't have servers... Just Routers, Switches, Console
Servers, and your other Network Hardware.
'console server' is, in one view of the world, now 'usb console server' ...
The problem with USB is you can only wire a USB 2.0 Cable up to 15' (Per
Google).... And you have to purchase a cable premade.
this is a fairly salient point :( If I don't have a console server in
each rack (or pair of racks) but as a row element, now I have
significantly shorter row length before I can't console anymore.
Where as with a Serial Console you can go around 100', not to mention about
just about everyone has a crimper, rj45 ends, and cat5 cable, to run and make
cables as needed.
maybe the ubiquity of usb consoles will drive this i the right
direction as well?
Assuming something is broke...With USB let's say you rely on remote hands to do
a lot of work in the colo's. First they need to find a *Working Laptop*, then
you have to walk the tech through downloading the drivers and installing them
on there laptop. Hoping they have permissions to install software on there
laptops. Plus if it's really broke and you get no output, you will never be
sure if it's USB related or not. Where as serial it's just going to work, and
it's easy to test to see if it's working on not by hooking up to another device.
my guess is that most / all tech's have a usb-serial dongle at this
point, because who's laptop has serial ports anymore natively onboard?
mostly you're outlining 'operational practices and norms are not
accounted for yet in the usb-console design' right? which either is:
1) get out and write procedures/documentation for how this all should work
2) call back to 2005 and demand no usb in consoles on network equipment
I don't think 2 is feasible :( but 1 sure is... Also, it's sort of
funny to me that servers don't seem to be going this route?

Why not use udev rules so the ports are persistent? I did that on a pi that I
was using as an ice cast box. Based on the usb audio port on reboots I know
which device is which stream.

Assuming that this is really an USB device, and that the console port is
really an USB host port, it would be useful to know the USB decriptors
of the device. You wouldn't be willing to connect it to a Linux PC and
run "lsusb -vd", would you?
I'm inconveniently consoled into one via a combination of remote desktop
into windows -- linux console on a virtual machine -- screen
/dev/ttyACM0. Because of this posting lsusb -vd is taxing.
Linux has full support for the device. It sees it as cdc_acm.
The vendor id is 0x04e2 (Exar Corp). Product ID is 0x1410. I've got
two connected right now. This is in our lab and the windows box is
temporary. Our intention is to use a raspberry pi for the terminal server.
I'm obviously not in front of it, but I'm wondering if they can be
enumerated by something other than when they were plugged in. That's my
biggest hurdle for making a console server for them.. how to figure out
what router is connected to which USB port after a reboot, or someone
getting unpluggy with cables.
