Paradyne 9128-II, CSU, DSU, 9126-II manual Service Level Verification Performance Statistics

7. Operation and Maintenance

Service Level Verification Performance Statistics

These statistics appear when Service Level Verification (SLV) is selected from the Performance Statistics menu.

Main Menu → Status → Performance Statistics→ Service Level Verification

They only appear for the network interface and only if DLCIs are multiplexed or IP Enabled.

Information displayed on the SLV Performance Statistics screen depends on DLCI type. See Table 7-16, SLV Performance Statistics for Multiplexed DLCI or

Table 7-17, SLV Performance Statistics for IP Enabled DLCI.

On either screen, select PrevDLCI or NextDLCI to view statistics for the previous or next DLCI on the link. On the IP Enabled DLCI screen, select PrevPath or NextPath to view statistics for the previous or next path associated with the DLCI.

For standard or multiplexed DLCIs, the statistics collected by the unit depend upon the device at the far end of the connection. If the far-end device is a FrameSaver SLV unit, frame relay, latency, and FDR/DDR performance statistics are collected. The Frame Relay Delivery Ratio is the number of delivered frames/offered frames; the Data Delivery Ratio is the number of delivered octets/offered octets.

If the far-end device is a non-FrameSaver device, or a FrameSaver 9120 or 9620, only frame relay statistics are collected.

Table 7-16. SLV Performance Statistics for Multiplexed DLCI (1 of 3)

Statistic	What It Indicates
Far End Circuit	Number of the multiplexed DLCI or VPI/VCI (Virtual Path
	Identifier/Virtual Channel Identifier) at the other end of the
	connection.
	If the far-end circuit is a DLCI, the DLCI number (16–1007)
	appears. If a VPI/VCI, the number is displayed as xx,yyy, xx
	being the VPI number (0 –15) and yyy being the VCI number
	(32–2047).
	None appears if the unit has not communicated with the other
	end.
Far End IP Addr	IP Address of the device at the other end of the multiplexed
	DLCI connection.
	None appears if the FrameSaver unit has not communicated
	with the other end, or if the device at the other end of the
	multiplexed DLCI does not have an IP Address configured.
Dropped SLV	The number of SLV inband sample messages sent for which a
Responses	response from the far-end device has not been received.

*Only appears for FrameSaver units when the SLV Delivery Ratio option is enabled.
