• The Cisco TelePresence System web-based GUI provides access to statistics
for ongoing calls, or the previous call if the Cisco TelePresence System
endpoint is currently not in a call. Accounting management statistics include
the call start time, duration of the call, remote number, bit rate, and the
number of packets and bytes transmitted and received during the call. These
statistics are also available via an SSH CLI as well as through SNMP.
• The Cisco TelePresence System web-based GUI provides access to statistics
for ongoing calls, or the previous call if the Cisco TelePresence System
endpoint is currently not in a call. Performance management statistics include
parameters such as packet loss, latency, jitter, and out-of-order packets for
audio and video media streams. These can be used to assess the performance
of the network infrastructure in meeting service level agreements. These
statistics are also available via SNMP through the
CISCO-TELEPRESENCE-CALL-MIB.
• An IP service level agreements (IPSLA) responder within the Cisco
TelePresence System endpoint can be enabled, allowing the Cisco
TelePresence System endpoint to respond to packets sent by an IPSLA
initiator. IPSLA can be used to pre-assess network performance before
commissioning the Cisco TelePresence System endpoint onto a production
network, or used to assess ongoing network performance or when
troubleshooting.
• Access control to the individual Cisco TelePresence System endpoints is
currently handled via a local database, although the userid and password used
for access control are centrally managed via the configuration within the
Cisco Unified Communications Manager Administration web-based GUI.
• SNMP notifications can be set on the Cisco TelePresence System endpoint to
alert after failed access control attempts.
Note
Both static location-based admission control and RSVP are considered part of performance management
within this document, because the scheduling of resources is not done per end user, but to ensure that
necessary resources are allocated to meet service level requirements.
Cisco TelePresence Manager
From a management perspective, the primary functions of Cisco TelePresence Manager are resource
allocation, which is part of accounting management; and fault detection, which is part of fault
management. Cisco TelePresence Manager allocates Cisco TelePresence System endpoints (meeting
rooms) and Cisco TelePresence Multipoint Switch segment resources based on meetings scheduled by
end users through an e-mail/calendaring system such as Microsoft Exchange or IBM Lotus Domino.
Note that the Cisco TelePresence Manager has no knowledge of the underlying IP network
infrastructure, and therefore has no ability to schedule any network resources or provide Call Admission
Control (CAC) to ensure that the TelePresence call goes through during the scheduled time. Figure 6-27
shows an example of the resource scheduling functionality of Cisco TelePresence Manager.
