DHCP boot file options

Hi Gents,

 

I have an IPTV setup having ENSEO set top boxes, on conventional Cisco switches it was working perfectly with the below DHCP options configured:

 

ip dhcp pool ENSEO-STBs-Pool
import all
network 10.10.25.0 255.255.255.0
bootfile http://10.10.14.3/nevotv/default.aspx
default-router 10.10.25.1

 

I'm trying to do the same on Meraki dashboard as we are moving the whole setup to Meraki switches, so i added a DHCP configuration to the correct interface using the Boot Next-Server: 10.10.14.3 and the Boot filename: /nevotv/default.aspx (also tried \nevotv\default.aspx, and nevotv/default.aspx).

also i tried to use DHCP custom option 67 with type text and value: http://10.10.14.3/nevotv/default.aspx

 

all without success, the ENSEO STB is always not able to reach the boot file, so any ideas how could i reach the same DHCP boot file using Meraki setup?

I would make the bootfile name exactly:

http://10.10.14.3/nevotv/default.aspx

This format is not accepted in boot file name field, I tried but it was not accepted.

Have you tried the full url with option 66 instead of 67?

No I tried only option 67, will try this tomorrow and keep you posted.

option 66 didn't work as well

I would take a packet capture in both the legacy and the Meraki setup to see the difference in the dhcp options sent in both dhcp Offers.

the packet capture is ready with me but i can't attach text files to the post!!??

Two options:

 

Copy the relevant portions of the capture and paste them into a message.

 

Open the pcap in Wireshark and take a screenshot.

I think you are in a bit of bind because Meraki DHCP wont let you specify the parameter that you need ("http://10.10.14.3/nevotv/default.aspx").

 

Do you have another DHCP server someone in the network, so you could configure the Meraki kit to forward the DHCP queries, rather than being a DHCP server?
