-r retransmissions
Specifies the maximum retransmissions for the existing tunnel. Values
are 1 to 16; default is 8. If Tape Piplelining 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. When changing
this value, the value specified must be greater than the calculated value.
-s 0|1 Disable (0) or enable (1) selective acknowledgement (SACK) on the
existing tunnel.
-t 0|1 Disable (0) or enable (1) Tape Piplelining on the existing tunnel (requires
Fastwrite to be turned on as well).
-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.
-bstr 0|1 Disable (0) or enable (1) Byte Streaming on the existing tunnel. The
feature is disabled by default.
delete tunnel_id
Deletes specified FCIP tunnel.
qosmap tunnel_id arguments
Modifies (or resets to default), the VC to QoS mapping for a particular FCIP
tunnel. This table can be modified at any time without bringing down the
tunnel.
However, the FCIP tunnel must be configured with the fciptunnel
create/modify -M option before the actual mapping occurs.
The following operands are supported with fciptunnel qosmap:
tunnel_id Specifies the tunnel_id. Range is 0-7.
-default Resets/sets VC QoS map to default values.
-delete Deletes associated QoS map configuration file. Delete QoS mappings
before downgrading to pre-v6.0.0 firmware versions that do not support
QoS mapping. It removes the file from the config flash memory only. The
file is automatically reset to defaults if later used or modified.
vc_num When modifying the VC QoS map, specifies the virtual channel ID for
which the qosmap is modified. Valid values are 0 - 15.
When specifying vc_num, either the -Q or the -P option or both must be
specified.
-Q dscp
Specifies the Differentiated Services Code Point (DSCP) value to be
modified. Use the portShow fciptunnel geport all -qosmap command to
display current values. Supported range is 0-63.
