4. Configuration Options4-28 September 2002 9128-A2-GB20-80Configuring Service Level Verification OptionsSLV options are selected from the System menu (see Table 4-4, Service LevelVerification Options).Main Menu →Configuration →System→Service Level VerificationTable 4-4. Service Level Verification Options (1 of 3)SLV Sample Interval (secs)Possible Settings: 10 – 3600Default Setting: 60Sets the inband communications interval between FrameSaver SLV devices. Inbandcommunications are used to pass frames that calculate latency, as well as transmissionsuccess and other SLV information.10 – 3600 – Sets the SLV Sample Interval (secs) in seconds.SLV Synchronization RoleAvailable Settings: Tributary, Controller, NoneDefault Setting: TributaryDetermines the role the unit plays in maintaining synchronization of user history datacollection and storage between FrameSaver SLV and/or FLEX devices.Tributary – Uses network timing received from incoming SLV communications andprovides network-based synchronization information to other devices in the network.Controller – Uses its own internal time-of-day clock and provides synchronizationinformation to other devices in the network based upon its own clock.NOTE: Only one device in the network should be configured as the SLVsynchronization controller.None – Incoming timing information is ignored and no timing information is sent out. Thissetting should only be used when network synchronization is not desirable, or when asingle unit connects multiple networks or network segments.SLV TypeAvailable Settings: Standard, COS 1–COS 7Default Setting:If SLV Feature is enabled: StandardIf SLV Feature is disabled: COS 1Determines 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 SizeStandard – The options selected apply to standard FrameSaver SLV measurements,utlizing an EDLCI for FrameSaver-to-FrameSaver communication. This option is notavailable if the SLV Feature is disabed.COS 1–COS 7 – The options selected apply to this Class of Service. Different settingsmay be saved for each Class of Service.
