How to configure Option 156 in Linux dhcpd

[mshields]

We are putting in the Shoretel system in the next few weeks and our vendor has gave us a How-to worksheet for adding setting to DHCP. The problem is it's for Windows DHCP. We are a 100% Linux shop and use ISC's dhcpd. Does anyone have an example config for dhcpd.conf?

How to setup Option 156
How to setup DHCP option 156 for ShorePhone IP110/210/212k/530/560/560g telephones:
Step 1 Open DHCP Manager on your Microsoft DHCP server.
Right-click the DHCP server, and select Set pre-defined options.
Click Add.
Set Name to IP Phone Boot Server
Set Data Type to String
Set Code to 156 and add a description, if desired.
Navigate to the scope options and add option 156.
Set the value of option 156 to: ftpserver=10.1.0.100, country=n, language=n, layer2tagging=n, vlanid=10

Try using this statement in your dhcpd.conf:

# Shoretel custom option
option shoretel-server code 156 = string;
option shoretel-server "ftpserver=10.1.0.100, country=1, language=1, layer2tagging=1, vlanid=10";

*** This is going to turn on VLAN tagging and set the VlanID=10 to turn off VLAN tagging change the 1 to a 0 in "layer2tagging=1" The country=1 is for the US and the language=1 is for English.

Hallo, ich habe das selbe Problem.

Wenn ich

option code-156 code 156 = string;
option code-156 "ftpservers=....., country=5, language=3";

einstelle funktioniert es auch nicht. Die Telefone bekommen zwar eine IP
aber die anderen Optionen werden nicht mitgegeben ?

DANKE

Where abouts in the dhcpd.conf does this go? When I put it up top it doesn't seem to get passed on and when i put it within the scope i get an error starting the service saying option definitions may not be scoped.

Below is a dhcpd.conf file in a CentOS (Linux) server we use for a different style of system. I changed it to work on your server. Just copy and paste as needed then restart the dhcpd service. Notice the option is outside the subnet configuration and it uses "text" not "string".

authoritative;
ddns-update-style none;
option shoretel-server code 156 = text;

subnet 10.1.0.0 netmask 255.255.255.0 {
range 10.1.0.100 10.1.0.199;
default-lease-time 43200;
max-lease-time 43200;
option routers 10.1.0.1;
option subnet-mask 255.255.255.0;
option domain-name "xxxx.local";
option shoretel-server "ftpservers=10.1.0.100,configServers=10.1.0.10 , layer2tagging=0, country=1, language=1";
option domain-name-servers 192.168.10.2, 8.8.8.8;
