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 SLV 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.
