This topic describes port reservation in Cisco TelePresence Management Suite (TMS).
- How it works:
- Cisco TMS creates a temporary meeting on the Cisco TelePresence Server or multipoint control unit with the correct number of media ports.
- Cisco TMS knows how many media ports each conference bridge has, and it will not let users overbook the system.
- Set up the port reservation:
- On the multipoint control unit, enable media port reservation.
- Specify the number of audio and video ports for reservations.
- The conference is created by Cisco TMS with a defined date and time.
- Optionally, limit the ports to the number of scheduled participants.
A user wants to schedule a meeting with five participants on Monday from 2:00 p.m. (1400) to 4:00 p.m. (1600). Cisco TMS creates a temporary meeting at the correct time with the correct number of port resources for the five users, assuming that the resources are available at the scheduled time.
The setup steps take you through the setup process and show you how to prevent multipoint control unit oversubscription.
Nonscheduled calls may consume ports for scheduled conferences. The best practice is to dedicate each Cisco TelePresence Server or multipoint control unit to scheduled or nonscheduled meetings, but not both.
An unscheduled call can use ports that are reserved by Cisco TMS for scheduled conferences. In this case, oversubscription can occur. To prevent oversubscription, uncheck the Allow Bookings check box for the relevant multipoint control units. This action will create two multipoint control unit groups:
- The schedule-enabled multipoint control units are managed by Cisco TMS.
- Access is based on the best effort principle on the multipoint control units that are used for nonscheduled (ad hoc) conferences. Cisco TMS does not size ports on these multipoint control units, so overbooking can occur.
Specify the following information to adjust and optimize resource utilization:
- Specify default set up and tear down buffer, which reserves ports.
- Select Extend Scheduled Meeting Mode: Off, Endpoint Prompt, or Automatic Best Effort
Specify the default setup buffer and default teardown buffer. These buffers specify how early a user can dial into a meeting, and how long the bridge remains open after the meeting ends.
Ports are reserved for buffers during setup and tear down.
The Extend Scheduled Meeting Mode parameter specifies what happens at the end of the scheduled meeting time:
- Off: The meeting is disconnected.
- Endpoint Prompt: Prior to the end of the meeting, the user is asked if the meeting should be extended.
- Automatic Best Effort: If resources are available, the meeting is extended by 15 minutes for a maximum of 16 times. However, if any of the endpoints in the conference have bookings within the next 15-minute period, the meeting is disconnected for all endpoints.
If a recording device is included in the meeting, and the recording device stays as the last party in the meeting, the call is extended without other participants left in the meeting.
