Configuring Service Level Verification Options

SLV options are selected from the System menu (see Table 3-5, Service Level

Verification Options).

Main Menu→Configuration→System →Service Level Verification

Table 3-5. Service Level Verification Options (1 of 3)

SLV Sample Interval (secs)
Possible Settings: 10 – 3600
Default Setting: 60
Sets the inband communications interval between FrameSaver SLV devices. Inband
communications are used to pass frames that calculate latency, as well as transmission
success and other SLV information.
10 – 3600 – Sets the SLV Sample Interval (secs) in seconds.
SLV Synchronization Role
Available Settings: Tributary, Controller, None
Default Setting: Tributar y
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.
SLV Type
Available Settings: Standard, COS1–COS 7
Default Setting:
If SLV Feature is enabled: Standard
If SLV Feature is disabled: COS1
Determines the type of SLV measurements to which these other SLV options apply:
SLV Timeout Error Event Threshold
SLV Timeout Clearing Event Threshold
SLV Round Trip Latency Error Threshold
SLV Latency Clearing Event Threshold
SLV Packet Size
Standard – The options selected apply to standard FrameSaver SLV measurements,
utlizing an EDLCI for FrameSaver-to-FrameSaver communication. This option is not
available if the SLV Feature is disabed or if Service Type is PPP.
COS1–COS 7 – The options selected apply to this Class of Service. Different settings
may be saved for each Class of Service.
