How Cisco TMS communicates with managed
systems

Cisco TMS uses HTTP/HTTPS when communicating with managed endpoints and infrastructure products.
In addition, SNMP and FTP are used for communicating with some older endpoints, such as the Cisco
TelePresence System MXP series.
In addition, SNMP and FTP are used for communicating with some older endpoints, such as the Cisco

Managed systems also initiate connections to Cisco TMS. Examples of such connections include
phonebook requests, boot and registration events, and heartbeats from systems behind a firewall. Each
Cisco TMS-managed system must therefore be configured with an External Manager Address, which is used
for contacting Cisco TMS.

System connectivity status
The system connectivity status defines the network location of all systems managed by Cisco TMS. The
status may be set by the administrator when adding the system, manually updated at a later stage, or
modified automatically by Cisco TMS.
