between SCADA frames without reaching the 500-ms limit. If the SCADA
host application has a timeout lower than 500 ms, this parameter should be set
to 1. This then ensures a minimum latency for SCADA applications.
However, it will slow IP traffic since only one IP frame at a time can be
placed in the hardware transmit queue.
Default CIR (bps) This is the Committed Information Rate (in bits per second) provided by your
frame relay service provider. The unit will apply this value to each DLCI
learned from the network side to gather statistics and to perform CIR
enforcement, if required. If a DLCI is configured with a CIR different from
the default, the DLCI configuration will be used instead.
Values: 0–1536000
Default: 0
Default Be Rate (bps) This is the Excess Burst Rate (in bits per second) provided by your frame
relay service provider. The unit will apply this value to each DLCI learned
from the network side to gather statistics and to perform CIR enforcement, if
required. If a DLCI is configured with a different Excess Burst from the
default, the DLCI configuration will be used instead.
Values: 0–1536000
Default: 0
Enforce CIR and Be If this parameter is set to “Yes,” the unit will enforce Committed Information
Rate and Excess Burst.
Values: No, Yes
Default: No
NOTICE: The Auto Diagnostic parameter must be set to “Yes” to enforce CIR and
Be.
Management DLCI If there is a DLCI entered (and submitted) in this field, it will be the only
DLCI that looks for in-band management packets. If a value of “0” (zero) is
entered in this field, all DLCIs will look for management packets.
Management Auto IP
DLCI
If this parameter is set to “Yes,” the unit will monitor the specified
management DLCI for 5 pings over 5 seconds, after which the unit uses the
destination address as its management IP address.
FrameStart Auto
Diagnostic
When this parameter is set to “Yes,” the unit will always source LMI on both
sides of the frame relay connection. The unit will dynamically learn the type
of link management used on each side of the connection (Network and
Serial).
When set to “No,” the unit will monitor LMI between the Serial and the
Network port. If one side of the connection goes down, it will source LMI
until the connection goes back up, and will automatically go back to Monitor
mode once both sides are up. In Monitor mode, the unit will switch all frames
received between the network and the serial port regardless of the number of
DLCIs or frame size.
