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

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 3-14, SLV Performance Statistics for Multiplexed DLCI or
Table 3-15, SLV Performance Statistics for IP Enabled DLCI .
If service type is Frame Relay, you can 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. The DLCI field is not displayed if service type is PPP.
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 an iMarc 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-iMarc device, or an iMarc 9120 or 9620, only frame
relay statistics are collected.
Table 3-14. 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 iMarc 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
Responses The number of SLV inband sample messages sent for which a
response from the far-end device has not been received.
* Only appears for iMarc units when the SLV Delivery Ratio option is enabled.
