HTTP Generic Setup
Issue 3 January 2014 51
DHCPACK setting of parameter values
Since the DHCP site-specific option is processed after the DHCP fields and standard options,
any values set in the site-specific option will supersede any values set via DHCP fields or
standard options, as well as any other previously set values. Values that can be set using the
DHCP site-specific option are listed in
Parameters set by DHCP in a site-specific option on
page 45.
Parameters L2Q, L2QVLAN, and PHY2VLAN are not set from a site-specific option if their
values were previously set by LLDP. For more information, see
About Link Layer Discovery
Protocol (LLDP).
HTTP Generic Setup
You can store the binary file, upgrade file, and settings file on an HTTP server. With proper
administration, the deskphone seeks out and uses that material. Some functionality might be
lost by a reset if the HTTP server is unavailable. For more information, see
Administering the
DHCP and File Servers on page 43.
