The following two operands are exclusive; you can either specify a committed
rate or a minimum and maximum rate for circuit 0. You can modify these
parameters later with fciptunnel modify.
comm_rate
Specifies the committed traffic rate on the FCIP tunnel in Kbps. The valid
range is 10,000 Kbps to 1,000,000 Kbps for 1G ports and 10,000 Kbps to
10,000,000 Kbps for 10G ports. There is no default. Both sides of the circuit
must have matching configurations.
-b | --min-comm-rate value, -B | --max-comm-rate value
Alternately you may set a minimum and a maximum for the committed rate to
configure the tunnel for Adaptive Rate Limiting (ARL), which allows for a
more effective sharing of bandwidth between applications. The valid range is
10,000 Kbps to 1,000,000 Kbps for 1G ports and 10,000 Kbps to 10,000,000
Kbps for 10G ports. The maximum committed rate is the combined maximum
committed rate of all configured circuits and it can be no larger than five times
the minimum committed rate. Both sides of the circuit must have matching
configurations.
Beginning with Fabric OS v7.0, you can configure minimum and maximum
rates for each circuit of a tunnel using the XGE ports on the FX8-24 blade.
This provides a maximum guaranteed rate of 10Gbps combined for all
tunnels over a single 10GbE port and a maximum rate of 10Gbps for any
single circuit. This feature is backwards compatible with 1GbE ports on either
the Brocade 7800 Extension Switch or on the Brocade FX8-24 Extension
Blade. For connections between 10GbE ports, ARL is supported only if Fabric
OS v7.0 is running on both switches.
Optional tunnel_arguments for fciptunnel create and modify include the
following. Tunnel parameters are by default disabled. To change the default
(for example, enabling FastWrite) with fciptunnel create, specify the
parameter only. To modify any of these parameters with fciptunnel modify,
specify the parameter and one of the values in square brackets.
-f | --fastwrite [0 |1]
Disables (0) or enables (1) FCIP FastWrite on the specified FCIP tunnel.
-t | --tape-pipelining [0-2]
Configures Open Systems Tape Pipelining on the specified FCIP tunnel. By
default, OSTP is disabled (0).
When using this operand with fciptunnel create, specify one or more of the
following operands:
-t | --tape-pipelining
Enables write-read Tape Pipelining (FCIP FastWrite must also be enabled.)
-N | --no-read-pipelining
Disables tape read-pipelining. This operand is valid only with fciptunnel
create and -t must be specified enabling the feature. The combination of -t
and -N effectively enables tape write-pipelining.
When using this operand with fciptunnel modify, specify one or more of the
following:
-t | --tape-pipelining mode
Modifies the Open System Tape Pipelining configuration. Specify one of the
following modes:
0
Disables Tape Pipelining
