Far End Name The system name configured for the far-end FrameSaver device,
obtained using its IP address. Unknown appears if the far end
device is not a FrameSaver or if no response has been received
since the last reset.
COS Type Mismatches The number of SLV packets received that indicate a mismatch
between the Class of Service definitions in the near-end and
far-end devices.
Far End Type The model type of the far-end FrameSaver device, obtained
using its IP address. Unknown appears if the far end device is
not a FrameSaver or if no response has been received since the
last reset.
COS Name The names for different Classes of Service defined using the
Class of Service Definitions screen. See
Configuring Class of
Service Definitions
in Chapter 4,
Configuration Options
.
COS ID The ID numbers (1–7) of the Class of Service definitions.
Last RdTrip Current round trip latency, measured in milliseconds, between
the FrameSaver unit and the device at the other end of the DLCI
connection.
“--” appears if communication with the far-end device is not
successful.
Min RdTrip Minimum round trip latency measured over the last 15 samples
between the FrameSaver unit and the device at the other end of
the DLCI connection.
“--” appears if communication with the far-end device over the
last 15 samples has not been successful.
Avg RdTrip Average round trip latency between the FrameSaver unit and the
device at the other end of the DLCI connection.
Average round trip latency is measured every SLV sampling
interval and the average is computed (using packets with the
configured SLV Packet Size, as shown in Table 4-5, Service
Level Verification Options) over the previous 15 samples. If SLV
Packet Size is changed, a new average is not available until a
new sample has been received.
“--” appears if communication with the far-end device over the
last 15 samples has not been successful.
Max RdTrip Same as average (Avg RdTrip), but storing the maximum value
of latency over the previous 15 samples.
“--” appears if communication with the far-end device over the
last 15 samples has not been successful.
Dropped SLV
Responses
The number of SLV inband sample messages sent for which no
response from the far-end device has been received.
