Parameter Data Precedence; The Administrative Process - Avaya 1600 Series Administrator's Manual

Administration Overview and Requirements

Parameter Data Precedence

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. Manual administration, with the two exceptions described for the system parameter
STATIC on page 66,
2. DHCP,
3. HTTP,
4. the Avaya Media Server, and finally,
5. 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, the usual sequence applies through HTTP. If the VLAN ID after
HTTP is not zero, any VLAN ID from the media server is ignored.
