portCfg 2 -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 Enables Byte Streaming on the specified tunnel. Byte streaming allows the Brocade switch to communicate with third party WAN optimization hardware. The WAN optimization hardware connects on the GE ports configured for FCIP. The TCP Byte Streaming feature is supported only on the Brocade 7500 or the FR4-18i blade configured for FCIP GE ports. modify tunnel_id [arguments] Modifies the properties of the existing FCIP tunnel. This disrupts 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 re-create 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. Uncommitted tunnels compete for bandwidth. Changing com_rate is potentially disruptive. -d description Modifies the tunnel description. -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. -t 0|1 Disable (0) or enable (1) read/write Tape Pipelining on the existing tunnel (requires Fastwrite to be enabled). -k timeout Specifies the keep alive timeout, in seconds, for the existing tunnel. Valid timeout values are 8 to 7,200; default is 10. If Tape Piplelining is enabled, minimum value is 80. -q control_dscp -Q data_dscp DSCP (DiffServ Code Point) Marking for a tunnel's TCP control connection. Valid range is from 0 to 63 (inclusive). Default value is 0. DSCP(DiffServ Code Point) Marking for a tunnel's TCP control connection. Valid range is from 0 to 63 (inclusive). Default value is 0. -M -m time Turns on default QoS mapping in the specified tunnel. Default is off. There are two ways of prioritizing network traffic over FCIP tunnels: Differentiated Services (DSCP) and Layer 2 Class of Service (L2CoS). If the -M option is set, the VC on the FCIP outbound frame is mapped to both a DSCP and L2CoS value. These default values can be modified on a per-FCIP tunnel basis with the fciptunnel qosmap option. The -M option can be turned on or off at anytime. Qosmap settings are unaffected by the -M option. Specifies the minimum retransmit time, in milliseconds, for the existing tunnel. Valid time values are 20 to 5,000; default is 100. Fabric OS Command Reference 541 53-1001186-01
