-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.
-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 16;
default is 8. If tape pipelining is enabled, default value is calculated based on
the minimum retransmit time to ensure that the 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).
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 then recreate it.
Option specific [optional_args] for modify include:
-b comm_rate Specifies the new desired committed rate for the existing FCIP 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.
-q control_dscp
DSCP (DiffServ Code Point) Marking for tunnel's tcp control connection. Valid
range is from 0 to 63 (inclusive). Default value is 0.
-Q data_dscp DSCP (DiffServ Code Point) Marking for tunnel's tcp data connection. Valid
range is from 0 to 63 (inclusive). Default value is 0.
-m time Specifies the minimum retransmit time, in milliseconds for the existing
tunnel. time values are 20 to 5,000; default is 100.
