This will happen if you have a port admin up but oper down or if you don't have 
both power supplies connected.  We shutdown unused ports and lights go green.

Our biggest frustration is that they fixed PBR in v3.16, but local PBR still 
doesn't work properly.  We've been waiting over a year thus far.

For reference, the PSU sticking out and bracket things is not true on all 
ASR920 models - some have fixed PSUs, and the ones that are not a full 19” wide 
have poor brackets.

As I'm sure you know, Cisco ditched this in N7k sup-2, because "customer didn't 
want it". So evidently, no, people aren't putting this in RFPs :o(

Which would be nice, if it did not require a proprietary client app that
only works on Windows 7, and only with a particular bluetooth chip that
is out of production.

(Besides that, using Airconsole over BT is actually quite nice :-) )

Ethernet or RS232 on control-plane really isn't an OOB port at all, as
it fate-shares the same hardware and software, IOS dead, RS232 dead.
Of course on RS232 you at least can send break signal, to start
executing rommon and boot the box from there. But my understanding is
that virtually no one uses this feature for some reason, and indeed it
does not work in IOS-XR 9k today at all.
It seems people are content with Nike and Corolla OOB.

Yeah I presume so.

An RJ45 with two USB A holes underneath is a pretty common part as well. I 
guess it was partially a price thing - probably similar to why serial ended up 
on RJ45 in the first place? I haven’t been around long enough to know :-)

Nah... since that BU is all fancy on USB-A for everything... my bet is
on USB-A not RJ45.  And they will call it "USB C power supply".

Re: [c-nsp] ASR920 "console" port....ugh

Thanks Nathan - I really question Cisco's thought processwhat was "wrong" 
with the traditional style RJ45 console port?  Took up too much realestate??

We have rack kits for them, but Ive only just unpacked 2, found the fun console 
ports, got that working, and upgraded XE on them bothhavent installed rack 
kits yet, but thanks for the heads upcan they still be racked on top of 
each other, or does the rack kit cause issues?

Im going to order in a few of these 

A920-CONS-KIT-S
Serial Console Kit, USB-to-RJ45 cable

Hopefully they will do what I needIm assuming they will be very inexpensive 
lol

Hi, there is both a USB signalled console port, and an RS232 console. The RS232 
console uses a USB style connector, which is very, very poor. Cisco sell a 
cable that gives you an RJ45 RS232, it’s just wires, no active components in 
there.

I’m not sure I’ve got one handy, but when I do, I can reverse engineer the 
cable for you so you can get the pinout if you like - but I don’t imagine it’d 
be hard to figure out if you’ve got a multimeter, USB connectors only have 4 
pins.

Also, have you got ASR920 rack mount ears? Ever notice that they’re taller than 
1RU because of the folded bits? It’s a pretty bad product from a physical 
design POV.

Well, if done properly, it's actually easier to the admins than having
to carry around a usb-to-serial adapter all the time (since almost all
current machines do not have a built-in serial port anymore).

"properly" implies something else, though, like:

 - the "real" USB console has a mini-b or micro-B plug, so a bog-standard
   USB cable otherwise used to charge your mobile will do the job (as for
   driver installation, well, if you can find a USB-to-serial chip that
   windows supports by default, even better - but otherwise, unavoidable
   misery.  On Linux, it just works with the common chipsets)

 - for those with classic serial ports, or modem needs, there is a standard 
   serial console with *standard* layout (read: Cisco RJ45)

Yes.

Check out "Figure 1-2 Front Panel of Cisco ASR-920-12CZ-D Router" on this page:
http://www.cisco.com/c/en/us/td/docs/routers/asr920/hardware/installation/guide/ASR920_HIG/overview.html

"Console port (TIA/EIA-232F)" is RS232 on a USB connector.
"Auxiliary Console port" is also RS232 on a USB connector.

The only USB signalled ports are down the other end of the router.

Cisco sell a cable that gives you an RJ45 RS232, it???s just wires, no active 
components in there.

Those folded bits are so it can sit flat when in wall mount mode, but they make

Well, if done properly, it's actually easier to the admins than

almost all current machines do not have a built-in serial port

but otherwise, unavoidable misery.  On Linux, it just works with the

USB console is a good idea but the execution of this changeover was botched.

As of today we have most routers and switches rolling out with USB 
serial ports and what appears to be USB->Serial chips onboard to do the 
translation.  This required only a standard mini-b to USB cable to work.


Big tick there.  The hardware teams did a good job on their part of the 
job and the implementation of hardware is usually good.


But where Cisco seriously lost all credibility with this was the 
software/driver support.


As of today:

Windows 7 driver - available on CCO and works OK
Windows 8 driver - never supported
Windows 8.1 driver - never supported
Windows 10 driver - seems to be built into Windows 10

Note that the Windows 7 driver did not work on Windows 8.  And in 
practice on every laptop I tried it on the driver got in a messed up 
loop whereby it created 255 COM ports in Windows before deciding that 
there were none left.  This left a right royal mess in device manager to 
clean up.


At least a part of this bug was being tracked under CSCuh52585 which has 
never been made customer visible.


There was some comment on this in:

https://supportforums.cisco.com/discussion/11996231/usb-console-drivers-windows-8

In the end I just went and bought a decent dongle that did have good 
driver support and haven't had to deal with the problem since.


There are still some routers which don't have USB console ports such as 
the C819G's though.  So it's not quite yet ubiquitous.  But that's the 
exception not the norm.

Ahh right, the ASR-920-4SZ-A model (which I have) isn’t as wide, so the 
brackets take up the extra space. Because they’ve got an extra couple cm to 
cover, they need the extra thickness so the bracket works in wall mount mode.

No replaceable PSUs on these either. You either get naff brackets or PSUs that 
stick out the front, I guess.

Caused issues for me, yeah.

Those folded bits are so it can sit flat when in wall mount mode, but they make 
it taller than 1RU. Pretty stupid.

Re: [c-nsp] ASR920 "console" port....ugh

[Erik Sundberg]

Just finished installing a ASR920 tonight... I had the same issue, just order 6 
of those console kits This is really annoying...

My rack mount brackets don't look like that...

Some changes from Cisco Norm for the ASR920
- No RJ45 console port, very disappointing
- The power plug for AC is a C15 not a normal C13
- Services Instances are 1-4000 not 4096. We usually keep the service instance 
id and the stag the same. You couldn't add another 96 service instances.
- Interface layout on the switch would have been nice if it was like cisco 
switch top left is the first port, but on the asr920 it's the bottom right is 
port G0/0/0.
- interface number start with 0 like a router, instead of 1 like the ME3800's
- Management Interface vrf name is forced to Mgmt-intf, you can't change it.
- It's weird that the power supplies stick out a 1/4" inch

Other wish list for the ASR920
- 36x or 48x 1G port model
- 24x 10G Port model
- I really don't like the licensing model, your almost always stuck buying the 
bulk license.

Here is the port numbering any port layout that I was talking about. Backwards 
from a ME Switch, but I guess this is a router...

Starts lower left with 0

Hi, there is both a USB signalled console port, and an RS232 console. The RS232 
console uses a USB style connector, which is very, very poor. Cisco sell a 
cable that gives you an RJ45 RS232, it’s just wires, no active components in 
there.

I’m not sure I’ve got one handy, but when I do, I can reverse engineer the 
cable for you so you can get the pinout if you like - but I don’t imagine it’d 
be hard to figure out if you’ve got a multimeter, USB connectors only have 4 
pins.

Also, have you got ASR920 rack mount ears? Ever notice that they’re taller than 
1RU because of the folded bits? It’s a pretty bad product from a physical 
design POV.

Yes.

Check out "Figure 1-2 Front Panel of Cisco ASR-920-12CZ-D Router” on this page:
http://www.cisco.com/c/en/us/td/docs/routers/asr920/hardware/installation/guide/ASR920_HIG/overview.html

"Console port (TIA/EIA-232F)” is RS232 on a USB connector.
"Auxiliary Console port” is also RS232 on a USB connector.

The only USB signalled ports are down the other end of the router.

Is that the "EIA console" port?  On an USB A-type connector?

From the description I assumed that this would be some sort of standard
USB RS232 cable, but what you write scares me deeply...
