DHCP boot file options

[Ahmed83]

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?

[Ahmed83]

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

[Ahmed83]

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.

[Ahmed83]

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?
