question related to DHCP option 66 and multiple class

npereira · 11-16-2017, 12:22 PM

Hi,

I have several different types of phone on my voice network but they all provision using option 66 with a tftp server address only (polycoms).

Im adding Yealink phones that need to be provisioned to a different server using a HTTP URL.

It doesnt look like they are picking up the tftp-server-name or that option does not allow for a URL based entry.

Here is what the dhcpd currently looks like: (the issue is with the yealink)

Code:

class "yealink" {
        match if substring (hardware, 1, 3) = 00:15:65;
        option tftp-server-name "http://10.10.10.10/provisioning/sdgdfg63oz/";
}


class "polycom" {
        match if substring (hardware, 1, 3) = 00:04:f2;#grabs all polyconm phones based on mac if its
                                                        #not polycom watch out
}

class "polycom-kirk" {
        match if substring (hardware, 1, 3) = 00:13:d1;
}

class "linksys" {
        match if substring (hardware, 1, 3) = 00:0e:08;
}

group phones {
        option routers 10.44.16.1; #router ip for server
        option ntp-servers 10.44.16.10; #same

        subnet 10.44.16.0 netmask 255.255.255.0 {
                option routers 10.44.16.1;
                option tftp-server-name "ftp://polycom:456@10.44.16.10";#asterisk server address
                range 10.44.16.50 10.44.16.254;#range for phone ips over dhcp
        }
}

can someone let me know what im doing wrong here? thanks

class "yealink" {
match if substring (hardware, 1, 3) = 00:15:65;
}
class "polycom" {
match if substring (hardware, 1, 3) = 00:04:f2;#grabs all polyconm phones based on mac if its
}
class "polycom-kirk" {
match if substring (hardware, 1, 3) = 00:13:d1;
}
class "linksys" {
match if substring (hardware, 1, 3) = 00:0e:08;
}
subnet 10.44.16.0 netmask 255.255.255.0 {
option routers 10.44.16.1;

pool {

option tftp-server-name "ftp://polycom:456@10.44.16.10";#asterisk server address
allow members of "polycom";
allow members of "polycom-kirk";
allow members of "linksys";
}
pool {
# Yealink

}
}
