Appendix A: Glossary

Term Description
802.1P 802.1Q defines a layer 2 frame structure that supports VLAN identification and a QoS
802.1Q mechanism usually referred to as 802.1P.
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 deskphone. 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 device on the network.
Call Server In an Avaya SIP environment, the "call server" is the combination of Session Manager
and 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 9601, 9608, 9608G, 9611G, 9621G, or 9641G IP deskphones 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.
EAP Extensible Authentication Protocol, or EAP, a universal authentication framework
frequently used in wireless networks and Point-to-Point connections defined by RFC
3748. EAP provides some common functions and a negotiation of the desired
authentication methods, two of which are EAP-MD5 and EAP-TLS. When EAP is
invoked by an 802.1X enabled NAS (Network Access Server) device such as an
802.11 a/b/g Wireless Access Point, modern EAP methods provide a secure
authentication mechanism and negotiate a secure PMK (Pair-wise Master Key)
between the client and the NAS.
H.323 A TCP/IP-based protocol for VoIP signaling.
