Glossary
#
802.1D: 802.1D is reported only if it is enabled.
802.1p: 802.1p is the IEEE endorsed Layer 2 traffic prioritization setting.
802.1Q: The 802.1Q field indicates the Virtual LAN to which this device has been assigned.
A
Acoustic Echo Cancellation: The acoustic echo cancellation metric indicates if an endpoint is
configured for full-duplex, half-duplex or acoustic echo cancellation mode. The acoustic
echo cancellation metric is an enumerated type metric. The possible values are: 0 = Half-
duplex, 1 = Full-duplex, 2 = AEC. There is no acoustic echo cancellation on the VoIP
engines. Acoustic echo cancellation is a feature for IP phones only.
Alarm: A Trap or Alarm is a message sent by a Windows SNMP Agent to a Trap Manager,
console, or terminal to indicate the occurrence of a significant event, such as a
specifically defined condition or a threshold that was reached. It is also referred to as an
Alarm. The Trap Manager is typically configured to be the HP OpenView or Avaya
Network Management Console but any Trap Manager application can be used with the
AVAYA VoIP Monitoring Manager.
Apache: Apache HTTP server is an open-source HTTP server that is maintained by the Apache
Software Foundation. A free download is available from http://www.apache.org. Follow
the links to the HTTPD (HTTP daemon, web server). Note that Apache is installed as part
of the Integrated Management Windows Server.
AVAYA-VMON-MIB: The AVAYA-VMON-MIB is used for the storage of VoIP Monitoring
Manager trap configuration. (The ASN.1 definitions of this MIB and associated Traps are
included as text files in the installation.)
C
Canonical Name: The canonical name or CNAME is the unique identifier for each participant
within one RTP session, or set of related RTP sessions. The format is user@host, or host
if a user name is not available as on single-user systems. For both formats, host is either
the fully qualified domain name or IP address of the host from which the real-time data
originates. For Avaya VoIP systems CNAMEs are of the format: IP Telephone:
ext<extension>@<IP address>, IP Softphone: exs<extension>@<IP address>, Gateway
Board: gwp@<IP address>, Gateway Box: gwt@<IP address>.
Child Endpoint: The terms parent and child endpoints are purely for describing the way
endpoints are displayed in the Results List. A parent is like the branch in a tree view. A
child is like a leaf in a tree view. The same endpoint can be shown as both a parent and a
child. Click on the expanding icon positioned in the far left column of the Results List to
expand the tree which displays a sub list with the child endpoints. A child endpoint
represents a session between itself and its parent. This is different from a parent
endpoint that just represents a physical endpoint.
CLAN: The CLAN is an IP interface (LAN interface) on an Avaya media server and provides
control signalling to IP phones, Softphones, and other media gateways.
CNAME: Refer to Canonical Name.
