-l | --legacy [0|1]

In Fabric OS v7.0.0, the connection process for FCIP tunnels has changed in
ways that make it incompatible with earlier firmware versions. Specifying the
--legacy allows connection to IPSec-configured tunnels that use pre-Fabric
OS v7.0.0 firmware versions. You enable or disable this option per tunnel.
This option is a disruptive modify request that causes the tunnel to bounce.
The command prompts for confirmation with an appropriate message.

-q | --qos high,med,low

Sets QoS percentages for all QoS priorities. The default values are 50%
(high), 30% (medium), and 20% (low). Each priority can have a minimum of
10%, the high must be greater than or equal to the medium, and the medium
must be greater than or equal to the low. The sum of percentages must equal
100%. Both ends of the tunnel must have the same QoS priority settings and
the switches must run Fabric OS v7.0.0.

Use the following operands to modify individual settings.

--qos-high percentage

Specifies the percentage for the high priority.

--qos-medium percentage

Specifies the percentage for the medium priority.

--qos-low percentage

Specifies the percentage for the high priority.

-F | --ficon [0|1]

improves the performance of certain applications when writing to tape over
extended distances.

--ficon-tape-read [0|1]

improves performance for certain applications when reading from FICON
tape over extended distances.

--ficon-tin-tir [0|1]

Enables (1) or disables (0) FICON TIN/TIR emulation. This feature enhances
recovery when a TIN/TIR exchange occurs as part of a channel recovery
operation during tape emulation. This feature is enabled by default
(recommended setting).
