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. SIP Software
Release 2.0 and up supports IEEE 802.1X using EAP-MD5 and EAP-TLS
authentication methods.
Application - Specific to a particular "application" running inside the telephone. For example,
specific configuration file downloading, 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, used, for example, to verify that the IP Address
provided by the DHCP server is not in use by another IP telephone.
Call Server In an Avaya SIP environment, the "call server" is the combination of SIP Enablement
Services (SES) and Avaya Communication Manager.
CLAN Control LAN, 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. The Domain Name System (DNS) is a distributed Internet directory
service. DNS is used mostly to translate between domain names and IP Addresses.
Avaya 9600 Series SIP IP Telephones can use DNS to resolve names into IP
Addresses. In DHCP, TFTP, and HTTP files, DNS names can be used wherever IP
Addresses were available as long as a valid DNS server is identified first.
