Configuring Option 43 to Transfer VLAN ID Assignment on a Linux DHCP Server

The following example (covering all the phones) illustrates how to configure Option 43 to transfer VLAN ID assignment on a Linux DHCP server.

option space AastraIPPhone;

 

 

option AastraIPPhone.cfg-server-name

code 02

= text;

option AastraIPPhone.contact-rcs

code 03

= boolean;

option AastraIPPhone.ActivateVLANHeader

code 08

= text;

option AastraIPPhone.VLAN-ID

code 09

= unsigned integer 32;

class "AastraSIP" {

 

 

match if ( (option vendor-class-identifier="AastraIPPhone6730i")

or (option vendor-class-identifier="AastraIPPhone9143i")

or (option vendor-class-identifier="AastraIPPhone9480i")

or (option vendor-class-identifier="AastraIPPhone9480iCT")

or (option vendor-class-identifier="AastraIPPhone6730i")

or (option vendor-class-identifier="AastraIPPhone6731i")

or (option vendor-class-identifier="AastraIPPhone6735i")

or (option vendor-class-identifier="AastraIPPhone6737i")

or (option vendor-class-identifier="AastraIPPhone6739i")

or (option vendor-class-identifier="AastraIPPhone53i")

or (option vendor-class-identifier="AastraIPPhone55i")

or (option vendor-class-identifier="AastraIPPhone57i")

or (option vendor-class-identifier="AastraIPPhone57iCT")

);

 

vendor-option-space AastraIPPhone;

 

 

 

option AastraIPPhone.cfg-server-name "http://192.168.174.200/aastra"; # option 43

option AastraIPPhone.contact-rcs

false;

 

# option 43

option AastraIPPhone.ActivateVLANHeader

"Aastra Telecom

";

# option 43

option AastraIPPhone.VLAN-ID

100;

 

# option 43

} # endClass

Enabling/Disabling DHCP Option 132 VLAN ID Using the Configuration Files

Use the following procedure to enable/disable DHCP Option 132 VLAN ID using the configuration files.

Configuration Files

For specific parameters you can set in the configuration files, see Appendix A, the section, “DHCP Option Settings” on page A-12.

Using Option 12 Hostname on the IP Phone

If you set the phone to use DHCP Option 12, the phone automatically sends this option to the configuration server. This option specifies the hostname (name of the client). The name may or may not be qualified with the local domain name (based on RFC 2132). See RFC 1035 for character set restrictions.

Notes:

The hostname of [<model><MAC address>] automatically populates the field on initial startup of the phone. For example, for a 6753i, the “Hostname” field is automatically populated as “53i00085D164435”, where the model number is “6753i” and the MAC address is “00085D164435”.

If the configuration server sends the hostname back to the phone in a DHCP Reply Packet, the hostname is ignored.

An Administrator can change the “Hostname” for the DHCP Option 12 via the configuration files, the IP Phone UI, and the Aastra Web UI.
