SLV Timeout Clearing Event Threshold
Available Settings: 1, 2, 3, 4 . . . 20
Default Setting: 1
Specifies the number of consecutive SLV messages that must be received before the
DLCI Inactive status is cleared.
1 – 20 – Sets the limit for the clearing event.
SLV Packet Size (bytes)
Available Settings: 64 – 2048
Default Setting: 64
Sets the size of packets, in bytes, that will be used for SLV communications. SLV
packets are used to track latency and other SLV-related variables.
When the packet size is changed, a new round trip and average latency calculation
must be performed, so these measurements will not appear on the SLV Performance
Statistics screen until a new sampling interval has occurred.
64 – 2048 – Sets the packet size for SLV communications.
SLV Synchronization Role
Available Settings: Tributary, Controller, None
Default Setting: Tributary
Determines the role the unit plays in maintaining synchronization of user history data
collection and storage between FrameSaver devices.
Tributary – Uses network timing received from incoming SLV communications and
provides network-based synchronization information to other devices in the network.
Controller – Uses its own internal time-of-day clock and provides synchronization
information to other devices in the network based upon its own clock.
NOTE: Only one device in the network should be configured as the SLV
synchronization controller.
None – Incoming timing information is ignored and no timing information is sent out.
This setting should only be used when network synchronization is not desirable, or
when a single unit connects multiple networks or network segments.
