TABLE 8 Circuit options
Option Argument Disruptive Description
Committed rate committed rate
Create behavior: Sets the
minimum and maximum
committed rate to the value
specified for committed rate.
Short option: -b and-B
Yes This option may be used on a portcfg
fciptunnel create command or on the
portcfg fcipcircuit create command to set a
committed rate for an FCIP circuit. When
this option is used on the portcfg
fciptunnel create command, the
committed rate applies only to circuit 0.
To modify the committed rate or if you
intend to use ARL on the circuit, use the -b
and -B options to set the minimum and
maximum committed rates.
If ARL is not going to be used you can use a
single data rate. If ARL is going to be used,
you must use the -b and -B options to
define minimum and maximum rates.
Values entered for -b and -B can be the
same and therefore describe a
configuration with a fixed data rate.
Adaptive rate limiting
(ARL)
Short option: -b
Long option: --min-comm-rate
Operands: kbps
Yes The minimum committed rate is a
guaranteed minimum traffic rate for an
FCIP circuit. The valid ranges for
-min-comm-rate are 10,000 Kbps through
10,000,000 Kbps for GbE ports and
10,100 Kbps to 100,000 Kbps for 10 GbE
ports (XGE).
NOTE: When added together, the
minimum committed rates for all
circuits cannot exceed the speed of
the GbE or XGE port.
Short option: -B
Long option: --max-comm-rate
Operands: kbps
Yes The maximum committed rate is the rate
that the tunnel will try to achieve, based on
bandwidth availability and network
performance. The valid ranges for
-max-comm-rate is
10,000 Kbps to 1,000,000 Kbps for GbE
ports and 10,000 Kbps to 10,000,000
Kbps for 10 GbE ports.
NOTE: When ARL is used, The link cost is
equal to the sum of the maximum
traffic rates of all established and
currently active lowest metric
circuits in the tunnel.
