default circuit. The default circuit created with the tunnel is automatically
assigned the circuit ID 0. You can modify the default circuit with the
fciptunnel modify command. To add additional circuits to an existing tunnel,
use the fcipcircuit create command.
modify [tunnel_arguments] [circuit_arguments]
Modifies the properties of an existing FCIP tunnel. To modify a tunnel, you
must specify at least one of the tunnel or circuit parameters for the command
to be effective. Any circuit attribute you change with the fciptunnel modify
command affects only the FCIP circuit 0. All other circuits remain unchanged.
To modify a circuit other than circuit 0, you must use the fcipcircuit modify
command.
In order to create a default circuit 0 with the tunnel, you must at least specify the following
circuit arguments with fciptunnel create:
remote_ip_address
Specifies the IP address for the remote end of the FCIP circuit.
local_ip_address
Specifies the IP address for the local end of the FCIP circuit.
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 10000 Kbps to 1000000 Kbps. 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 10000 Kbps to 1000000 Kbps. The maximum committed rate
can be no larger than five times the minimum committed rate, and both
sides of the circuit must have matching configurations.
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:
-t |--tape-pipelining
Enables write-read Tape Pipelining (FCIP FastWrite must also be
enabled.)
