-Q data-dscp Specifies the DSCP (DiffServ Code Point) Markingused for data TCP
connection of the FCIP tunnel. This Operand is optional. Range is 0 to 63
(inclusive). Default value is 0.
-r retransmissions
Specifies the maximum retransmissions. Values are 1 to 16; default is 8. If
tape pipelining is enabled, the default value is calculated based on the
minimum retransmit time to ensure that the TCP connection does not time
out before the host times out. The specified value must be greater than the
calculated value.
-s Disables selective acknowledgement code (SACK) on the specified tunnel.
-t Enable tape pipelining on the tunnel specified (requires fastwrite to be turned
on as well).
-ike policy Specifies the Internet Key Exchange (IKE) policy number to be used on the
specified tunnel. This option is must be used together with -ipsec and -key.
-ipsec policy Specifies the Internet Protocol security (IPSec)policy number to be used on
the specified tunnel. This option must be used together with -ike and -key.
-key preshared-key
Specifies the preshared-key to be used during IKE authentication. Specify a
double quoted string of alpha-numeric characters between 12 and 32 bytes
in length. This argument must be used together with -ike and -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.
-v vlan_id Creates an FCIP tunnel with VLAN Tagging and Class of Service (CoS). Specify
a vlan_id in the range between 1 and 4094. There is no default. If any other
VLAN option is specified, this must also be specified.
The following operands are optional with VLAN tagging:
-p Control L2 CoS
Specifies the pL2_Class_of_Service/Priority, as defined by IEEE 802.1p, for
the FCIP control connection. Range is 0-7. Default is 0.
-P L2 CoS
Specifies the PL2 Class of Service/Priority, as defined by IEEE 802.1p, for the
FCIP data connection. Range is 0-7. Default is 0.
modify tunnel_id [args]
Modifies the properties of the existing FCIP tunnel. This will disrupt the traffic
on the specified FCIP tunnel for a brief period of time. If IPsec is enabled on
the FCIP tunnel, the tunnel cannot be modified. To change it, you must delete
and recreate the tunnel.
Optional arguments for fciptunnel modify include:
-b comm_rate
Specifies the committed traffic rate on the FCIP tunnel in Kbps. Valid range
is 1, 544 to 1,000,000. Specify "0" for an uncommitted tunnel.
