DHCP Option 66 data gets mangled on the way to client ?

I have a 3750G issuing DHCP to a bunch of voip phones and mostly seems to work.
I have option 66 configured
ip dhcp pool Phones
   network 192.168.200.0 255.255.255.0
   default-router 192.168.200.254
   option 66 ip 192.168.200.200

Open in new window


but when I look at the phones GUI I see this odd value
	DHCP Option Server Path	@(HH

Open in new window

I'm not even sure what question to ask other than is there a different way I'm supposed to set option 66?

Shouldn't you provide an URL for option 66 (autoprovision path)?

Beside URL you may need to provide DNS server (and maybe domain name).

ip dhcp pool Phones
 network 192.168.200.0 255.255.255.0
 default-router 192.168.200.254
 ! domain-name <domain.name>
 dns-server <DNS_server_IP_add>
 option 66 ascii "<Whatever_phone_expect_to_ be_here>"

There is no DNS server available in this (linux) system. so if 66 requires a URL (or the phone does which I am investigating) then I can't use it after all.

The URL may contain an IP address, it doesn't necessarily need to use DNS. Something like \\10.10.10.10\autoprovision.html

ASCII and the URL, or ASCII and IP address?

Hi Qlemo

ascii and the ip address. No path after the IP was required - I'm sure that varies by client but in this case that's all that was needed.

Nobody was happier than I when they all snapped to life after that worked.
