802.1D 802.1Q defines a layer-2 frame structure that supports VLAN identification
802.1Q QoS mechanism is 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
Specific to a particular “application” running inside the deskphone. For example,
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.
ARP Address Resolution Protocol that you can use to verify that the IP address that the DHCP
server provides is not in use by another IP deskphone.
CLAN Control LAN, a type of Gatekeeper circuit pack.
CNA Converged Network Analyzer.
DHCP Dynamic Host Configuration Protocol, an IETF protocol used to automate IP Address
allocation and management.
DiffServ Differentiated Services, an IP-based QoS mechanism.
DNS Domain Name System, an IETF standard for ASCII strings to represent IP Addresses.
DNS is a distributed Internet directory service that translates domain names and IP
Addresses. For example, 9600 Series IP Deskphones use DNS to resolve names into IP
Addresses. DHCP, TFTP, and HTTP files use DNS names wherever IP addresses are
available and a valid DNS server exists.
Gatekeeper H.323 application that performs essential control, administrative, and managerial functions
in the media server. Sometimes called CLAN in Avaya documents.
H.323 A TCP/IP-based protocol for VoIP signaling.
HTTP Hypertext Transfer Protocol, used to request and transmit pages on the World Wide Web.
HTTPS A secure version of HTTP.
IEEE Institute of Electrical and Electronics Engineers, an organization that, among other things,
produces standards applicable to Local Area Network equipment.
