For XGE ports, this provides a maximum guaranteed rate of 10 Gbps
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.
In the previous releases, the maximum and minimum rates had to be
configured to the same value for circuits using the XGE ports on the FX8-24
blade. Beginning with Fabric OS v7.0, you can configure different values for
minimum and maximum rates for each circuit of a tunnel using the XGE ports.
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 [disable | enable]
Disables or enables the FCIP FastWrite on the specified FCIP tunnel.
-t | --tape-pipelining [disable | enable | write-only]
Configures Open Systems Tape Pipelining on the specified FCIP tunnel. By
default, OSTP is disabled .
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. This operand is supported on
the Brocade switch 7800 and FX8-24 blade only.
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:
disable
Disables Tape Pipelining
enable
Enables write-read Tape Pipelining (FCIP FastWrite must also be enabled).
write-only
Enables write-only Tape Pipelining (FCIP FastWrite must also be enabled).
-c | --compression compression_level
Configures compression on the specified FCIP tunnel. By default,
compression is disabled (0). Specify one of the following values on the
Brocade switch 7800 and FX8-24 blades:
none
Compression disabled
hardware
Enable standard compression.
moderate
Enable moderate compression.
