Service Level Verification Performance Statistics
The statistics in Table 7-12, SLV Performance Statistics for Multiplexed DLCI,
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
If DLCIs are multiplexed or IP Enabled
When the Advanced SLM Feature Set is activated
Information displayed on the SLV Performance Statistics screen depends on DLCI
type. See Table 7-12, SLV Performance Statistics for Multiplexed DLCI or
Table 7-13, SLV Performance Statistics for IP Enabled DLCI.
On either screen, select P
revDLCI or NextDLCI to view statistics for the previous
or next DLCI on the link. On the IP Enabled DLCI screen, select Prev
Path or
Nex
tPath 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 7-12. 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
Responses
The number of SLV inband sample messages sent for which a
response from the far-end device has not been received.
