Parameter Data Precedence
Issue 5 April 2010 15
If a given parameter is administered in multiple places, the last server to provide the parameter
has precedence. The precedence, from lowest to highest, is:
1. LLDP,
2. Manual administration, with the two exceptions described for the system parameter
STATICon page 72,
3. DHCP,
4. HTTP/HTTPS script file,
5. the Avaya Media Server, and finally,
6. Backup files, if administered and if permitted.
Settings the IP telephone receives from backup files or the media server overwrite any previous
settings, including manual settings. The only exception to this sequence is in the case of VLAN
IDs. In the case of VLAN IDs, LLDP settings of VLAN IDs are the absolute authority. Then the
usual sequence applies through HTTP/HTTPS.
Note:
Note: For the L2QVLAN and L2Q system values, LLDP settings of VLAN IDs are the
absolute authority only if the LLDP task receives the VLAN IDs before DHCP and
HTTP, and the DHCP client of the telephone is activated at all. If the LLDP task
receives the VLAN IDs after DHCP negotiation, several criteria must be
successful before the telephone accepts VLAN IDs from LLDP. For more
information, see Link Layer Discovery Protocol (LLDP).
The Administrative ProcessThe following list depicts administration for a typical 1600 Series IP Telephone network. Your
own configuration might differ depending on the servers and system you have in place.
1. LAN and applicable servers administered to accept the telephones.
2. Telephone software downloaded from the Avaya support site.
3. 46xxsettings file updated with site-specific information, as applicable.
4. 1600 Series Telephones installed. For more information, see the Avaya 1600 Series IP
Deskphones Installation and Maintenance Guide.
5. Individual 1600 Series IP Telephones updated using local procedures, as applicable. For
more information, see “Local Administrative Procedures” in the Avaya 1600 Series IP
