does not indicate their activity status. In the Hardware Monitor pane the Lan List displays the Collaboration Server LAN ports together with their Status indication.

The Hardware Monitor Status indications are summarized in the following table:

RTM LAN Indications

Status	Description
Active	The LAN port cable is connected.
Inactive	The LAN port cable is not connected.
Standby	The LAN Redundancy option is enabled and this LAN port is the redundant and in
	standby mode. In case of failure, this port becomes active.

Network Traffic Control

The Network Traffic Control mechanism controls the level of UDP packets generated by the system. It regulates a set of queuing systems and mechanisms by which UDP packets are received and transmitted to the network router.

During a conference the MPMx cards occasionally blast-out UDP packets which can cause overloads on the network. Collaboration Server bandwidth usage can increase to above the designated conference participant line rate settings, causing network bandwidth issues such as latency and packet loss.

Only supported in the MPMx Card Configuration mode.

Three Network Traffic Control Flags are used to control the Network Traffic mechanism:

●ENABLE_TC_PACKAGE -

When the flag is set to NO (default), Network Traffic Control is disabled on the Collaboration Server. Set the flag to YES to enable Network Traffic Control.

●TC_BURST_SIZE -

This flag regulates the Traffic Control buffer or max burst size as a percentage of the participant line rate. In general, higher traffic rates require a larger buffer. For example, if the flag is set to 10 and the participants line rate is 2MB, then the burst size is 200Kbps.

Default = 10 Flag range: 1-30.
