In addition to passive collection of statistics during calls, Cisco TelePresence System endpoints can also
function as IPSLA responders, as of Cisco TelePresence System version 1.4 or higher. IPSLA can be
used to pre-assess network performance before commissioning the Cisco TelePresence System endpoint
onto a production network. Optionally, IPSLA can be used to assess network performance when
troubleshooting a performance issue of a production device. See Network-Embedded Management
Functionality, page 6-2 for more information regarding the use of IPSLA for performance management.
The Cisco TelePresence System endpoint also supports extensive fault management capabilities through
diagnostics that can be used to troubleshoot the camera, microphone, and display components of the
Cisco TelePresence System endpoint. These diagnostics can be accessed through either the web-based
GUI interface of the Cisco TelePresence System endpoint, or through the SSH CLI. Additionally, SIP
log files stored within the Cisco TelePresence System endpoint can be accessed through the web-based
GUI to troubleshoot call signaling between the Cisco TelePresence System endpoint and the Cisco
Unified Communications Manager. Finally, the status of each component (displays, microphones,
speakers, and so on) of the Cisco TelePresence System endpoint can be accessed centrally via SNMP
through the CISCO-TELEPRESENCE-MIB. This management information base (MIB) is supported on
Cisco TelePresence System endpoints running software version 1.5 and higher.
The Cisco TelePresence System endpoint itself also plays a minor role in configuration management and
security management. In terms of configuration management, the configuration of the Cisco
TelePresence System endpoint, including specific hardware and software levels of each component
(displays, microphones, speakers, and so on), can be viewed through the web-based GUI interface, or
accessed through the SSH CLI. However, modifications to the configuration of the Cisco TelePresence
System endpoint is primarily controlled centrally by the Cisco Unified Communications Manager. In
terms of security management, access to the Cisco TelePresence System endpoint is via its local
database. However, the userid and passwords are configured centrally within the Cisco Unified
Communications Manager and downloaded to the Cisco TelePresence System endpoint.
Cisco TelePresence System 1.6 introduces password aging for the SSH and web-based GUI interface of
the Cisco TelePresence System endpoints. The security settings of the Cisco TelePresence System
endpoint are controlled via the Cisco Unified Communications Manager centrally, as discussed
previously. Finally, the Cisco TelePresence System endpoint also supports the ability to generate SNMP
traps for authentication failures when attempting to access the system. This can be used to monitor the
Cisco TelePresence System endpoints against brute-force password attacks.
Cisco TelePresence SNMP Support
As of this writing (CTS version 1.6), CTS, CTMS, and CTS Manager support the MIBs listed in
Table 6-5. Future versions of Cisco TelePresence may add additional SNMP MIB support.
