3850 PnP using DHCP option43

I have a 3850 and want it to download its config from APIC-EM with NO intervention of the switch i.e power the switch on and it automagicly connects to the APIC-EM and installs its confg.

So...I have a 3850 with new software ----  cat3k_caa-universalk9.SPA.03.06.05.E.152-2.E5

I have cleared the config using the following commands below .... as per the following link

==============Website screen output========================

configure terminal

crypto key zeroize

  no crypto pki certificate pool

no pnp profile pnp-zero-touch

end

delete nvram:*.cer

delete stby-nvram:*.cer (if the device has stack members)

write erase

reload

====================End of output======================

(all related networking is ok as it works with manual intervention... keep reading and you will see what I mean)

if i boot up the switch and just monitor it this is what it does please note when it asks if i want to enter config mode i have not entered anything as i want to simulate zero intervention. The second line appears after a while and will then just keep looping to no avail.

==============3850 screen output========================

Would you like to enter the initial configuration dialog? [yes/no]:

====================End of output======================

So the reason why it is trying to get to http://devicehelper.cisco.com/ca/trustpool is because when I check the config which at this point is at factory default, the following appears.

====================3850 screen output=================

pnp profile pnp_cco_profile

transport https host devicehelper.cisco.com port 443

====================End of output======================

If I go in and change the PnP profile and replace the url with the IP of my APIC-EM it conects and gets its config fine.

so the question is ....

How is the 3850 at factory default with no intervention ever going to connect to the APIC-EM if the factory default profile is making it go to the devicehelper.cisco.com URL. I could point internal DNS for that url to my APIC-EM but then what is the point of having option 43 with the APIC-EM IP in it.

Can you dig it.. can you diiiiiiiggggg iiiiiitttttttttt ???

Also how can I check ALL the DHCP values the 3850 has received from the DHCP server?

Also here is the config for the dhcp server

=========DHCP server output============

ip dhcp pool pnp_device_pool

   network 10.1.1.0 255.255.255.0

   default-router 10.1.1.1

   dns-server 192.168.64.14

   option 43 ascii "5A1N;B2;K4;I192.168.64.18;J80"

   option 60 ascii "ciscopnp"

============End===================

I have done a debug DHCP on the 3850 and all the above values are received just fine.

You're using HTTP and tcp/80 in your DHCP config.  But when you got it work, you used HTTPS and tcp/443 (which is what you want).  Try:

5A1N;B2;K5;I192.168.64.18;J443

See if that works.

ok thanks all have managed to get this working with the following string in option 43 with no DNS

"5A;B2;K4;I192.168.64.18;J80"

Hi,

Is the '1N' missing on purpose or is it just a typo? I am facing some similiar issues.

And does the pnp discovery even go through if there is some configuration present on a switch?

All my devices in my network are reachable and 'managed' but I was expecting them to be also in the unplanned section (I want to do some tests). I have option 43 configured/ with HTTP on my DHCP server and I can see in wireshark that all requests/ack are present.

Thank you in advance for your help!

PnP discovery will not initiate if there is existing configuration on your switch. 

1N missing is a typo.  For more detail, check solution guide: Solution Guide for Cisco Network Plug and Play - Cisco

First section of option 43 string:

5A1N;—Specifies the DHCP suboption for Plug and Play, active operation, version 1, no debug information. It is not necessary to change this part of the string.


Hi David,

It was because of a present startup configuration (even though it was just one inputed line).

The devices are present now in the unplanned device section.. I am wondering if there is some kind of "command" to invoke the pnp discovery process manually?

-B

Hi Belma,

PnP is designed so a default router/switch out of box can contact PnP server without any user input on device side.  There is a test command "test pnp discovery process".  But this is only for debugging purpose.

Your DHCP server setup has both DNS and Option 43 configs.  When your 3850 booted, there will be two discovery methods competing with each other.  In your case, DNS was able to resolve devicehelper.cisco.com first before Option 43. Try to remove " dns-server 192.168.64.14" from DHCP server and restart your test with factory default again.

Hi Sajid,

Op43 gets precedence over CCO discovery. From your output seems like the APIC EM at 192.168.64.18 did not respond to the device, hence, the device moved on to CCO. Can you do "sh pnp trace" and it will show you why was op43 not successful.

Please let me know how it goes.

Thanks,

Nikita

Ok get ready here comes an epic reply of log output.

Still no joy

just want to reply to everyone before I start.

Joseph Clark - Thanks for reply, I have tested by changing option 43 to use https, outcome below.

David Da-Wei Lin - Thanks for reply I did not know about this order of operation (so something learnt!) have removed DNS, outcome below.

Nikita Bhatia - Thanks for your reply out put of "sh pnp trace" to follow.

When I change the DHCP with no DNS but using k4 & port80 in option43 string

ip dhcp pool pnp_device_pool

   network 10.1.1.0 255.255.255.0

   default-router 10.1.1.1

   option 43 ascii "5A1N;B2;K4;I192.168.64.18;J80"

   option 60 ascii "ciscopnp"
