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.
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.
An Administrator can change the “Hostname” for the DHCP Option 12 via the configuration files, the IP Phone UI, and the
Aastra Web UI.
Configuration Files
For specific parameters you can set in the configuration files, see Appendix A, the section, “DHCP Option Settings” on pageA-12.
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.
