-key preshared-key
Specifies the preshared-key to be used during IKE
authentication. Its length can be up to a maximum length is 32
bytes. It must be a double quoted string of alpha-numeric
characters. The value of this key must be at least 12 bytes. This
argument must be used together with -ike and -ipsec. This
argument cannot be used together with -f (fastwrite) or -t (tape
pipelining).
-m time Specifies the minimum retransmit time, in milliseconds. time
values are 20 to 5,000; default is 100.
-n remote_wwn
Specifies the remote-side FC entity WWN.
-r retransmissions
Specifies the maximum retransmissions. retransmissions
values are 1 to 8; default is 8.If tape pipelining is enabled,
default value is calculated based on the mininum retransmit
time to ensure that tcp connection does not timeout before the
host times out. If the user changes this value, the value
specified must be greater than the calculated value.
-s Disables selective acknowledgement code (SACK) on the
tunnel specified.
-t Enable tape pipelining on the tunnel specified (requires
fastwrite to be turned on as well). This argument cannot be used
together with -ike, -ipsec or -key (IPSec).
• Note: Only a single IPSec-enabled tunnel can be configured on a port. No
other tunnels (IPSec or otherwise) can be configured on the same port. Jumbo
frames will not be supported on secure tunnels. Only a single route is
supported on an interface with a secure tunnel.
• modify tunnel_id
Modifies the properties of the existing FCIP tunnel. This will disrupt the
traffic on the FCIP tunnel specified for a brief period of time. However, if
the FCIP tunnel has IPSec enabled, it cannot be modified. To change it, you
must delete it and recreate it. optional_args for modify include:
-b comm_rate
Specifies the new desired committed rate for the existing
tunnel.
-c 0|1 Disable (0) or Enable (1) compression on the existing tunnel.
-f 0|1 Disable (0) or Enable (1) fastwrite on the existing tunnel..
-k timeout
Specifies the keep alive timeout, in seconds for the existing
tunnel. timeout values are 8 to 7,200; default is 10. If tape
pipelining is enabled, minimum value is 80.
-m time
Specifies the minimum retransmit time, in milliseconds for the
existing tunnel. time values are 20 to 5,000; default is 100.
