802.1D 802.1Q defines a layer 2 frame structure that supports VLAN identification and a QoS
802.1Q mechanism usually referred to as 802.1D.
802.1X Authentication method for a protocol requiring a network device to authenticate with a
back-end Authentication Server before gaining network access. Applicable 9600
Series IP deskphones support IEEE 802.1X for pass-through and for Supplicant
operation with the EAP-MD5 authentication method.
Application - Specific to a particular "application" running inside the telephone. For example,
specific configuration file downloading, backup and restore of user data, HTTP push, and the
Web browser are all internal applications that use the HTTP protocol. Similarly, the
RTCP and CNA clients are internal applications that can invoke traceroute. This term
does not include Web-page-based "applications" rendered in the Web browser.

allocation and management.

HTTP files, DNS names can be used wherever IP Addresses were available as long
as a valid DNS server is identified first.
