TABLE 4 Tunnel options
Option Argument Disruptive Description
Compression -c 0|1|2|3 Enables compression on an FCIP tunnel.
Compression is set by the portCfg
fciptunnel create or modify command, and
applies to traffic over all circuits in the
tunnel. Compression cannot be set or
modified by the portCfg fcipcircuit create
or modify command.
A value of 1 enables hardware
compression. A value of 0 disables
compression. A value of 2 enables a
combination of hardware and software
compression that provides more
compression that hardware compression
alone. This option supports up to 8 Gbps of
FC traffic. A value of 3 enables a software
only compression option that provides a
more aggressive algorithm. This option
supports up to 2.5 Gbps of FC traffic.
FCIP fast write -f 0|1 Enables or disables FCIP fast write. A value
of 1 enables FCIP fast write. A value of 0
disables FCIP fast write. FCIP fast write is
initially disabled, and must be enabled to
take effect.
OSTP -t 0|1 Enables or disables tape OSTP. A value of 1
enables OSTP. A value of 0 disables OSTP.
OSTP is initially disabled. Both FCIP fast
write and OSTP must be enabled if you
want to implement OSTP, as described in
“Open Systems Tape Pipelining” on
page 23.
Display remote FC WWN -n Causes the remote-side FC entity WWN to
display in the portshow output for the
VE_port.
Enable IPSec -i Enables a pre-defined IPsec policy on this
FCIP tunnel. Refer to“IPSec
implementation over FCIP tunnels” on
page 20 for information about IPSec
policies.
IKE V2 authentication
Key for IPSec
-K<key> The pre-shared key used during IKE
authentication.
