qosmap 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. The FCIP tunnel must be configured with the fciptunnel
create/modify -M option before the actual mapping occurs.
The following operands are supported with the fciptunnel qosmap option:
tunnel_id
-default Resets or sets the VC QoS map to default values.
-delete Deletes the associated QoS map configuration file. You must delete QoS
mappings before downgrading to pre-v6.0.0 firmware versions that do
not support QoS mapping. This command removes the file from the
configuration 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 QoS map 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 to 63.
-P l2cos
Specifies the L2 Class Of Service (COS) Tagging value. Use the portShow
fciptunnel geport all -qosmap command to display current values.
Supported range is 0 to 7.
Configures the FC port for FC FastWrite. Enables or disables FC FastWrite
between two Brocade 7500 switches or two Brocade chassis with FR4-18i
blades connected by Fibre Channel ISLs. FC FastWrite mitigateslatency
effects on SCSI writes, and improves throughputover a high-latency link. The
switch or blade must first be enabled for FC FastWrite using fastWriteCfg. You
can also use this command to list all ports configured for FC FastWrite. The
syntax for portcfg fastwrite is as follows:
portcfg fastwrite [slot/]port mode
Valid modes for fastwrite are:
Enables FC FastWrite on the specified port.
--enable
Disables FC FastWrite on the specified port.
--disable
Use this command to enable or disable FICON emulation in an FCIP tunnel
and modify associated parameters onan FCIP tunnel on a VE_Port. A feature
key is required to enable any of the FICON emulation processing. The tunnel
must be down or disabled to issue and process the FICON commands. The
results of this command are persistent. The syntax for portCfg ficon is as
follows:
portCfg ficon [slot/]Ge_Port tunnel_Id config |delete [FeatArgs] [ParamArgs]
Specifies the tunnel ID. The valid range is 0 to 7.
