-s Disables selective acknowledgement code (SACK) on the specified tunnel. -f Enables FCIP Fastwrite. -M Enables VC QoS mapping. -t Enables Read and Write Tape Pipelining on the specified tunnel. If Read and Write Tape Pipelining is enabled, Fastwrite must also be enabled. -n remote_wwn The remote-side FC entity WWN. -k timeout The keep-alive timeout in seconds. The range of valid values is 8 through 7,200 sec and the default is 10. If Tape Pipelining is enabled both the default and minimum values are 80 sec. -r retransmissions The maximum number of retransmissions on the existing FCIP tunnel. The range of valid values is 1 through 16. If Tape Pipelining is enabled, the number of retransmissions is calculated based on the minimum retransmit time to ensure that tunnel does not time out before the host times out (about 80 sec). Note that the value specified must be greater than the calculated value. -m time The minimum retransmit time, in milliseconds. The range of valid values is 20 through 5,000 ms and the default is 100 ms. -q control_dscp The DSCP marking for the FCIP tunnel's TCP control connection. The range of valid values is 0 through 63. The default is 0. Before configuring DSCP settings, determine if the IP network you are using implements PHB, and consult with the network administrator to determine the appropriate DSCP values. -Q data_dscp The DSCP marking for the FCIP tunnel's TCP data connection. The range of valid values is 0 through 63. The default is 0. Before configuring DSCP settings, determine if the IP network you are using implements PHB, and consult with the network administrator to determine the appropriate DSCP values. -v vlan_id The number used as the VLAN ID. This number is used in the IP frame to route the frame to a specific VLAN. -p control_L2Cos The layer 2 class of service used for control traffic. -P data_L2Cos The layer 2 class of service used for data traffic. -ike ike_number The IKE policy number to be used for this FCIP tunnel. -ipsec ipsec_number The IPsec policy number to be used for this FCIP tunnel. -key preshared_key The preshared key to be used during IKE authentication up to a maximum length of 32 bytes. It can be a double quoted string of alphanumeric characters. The range of valid values is 12 through 32 bytes. -bstr 0|1 Enables (1)/Disables (0) TCP Byte Streaming. Example: Creating an FCIP tunnel The following example creates one end of a tunnel over ge0 between remote IP address 192.168.10.1 and local IP address 192.168.20.1 with a tunnel id of 0, over VLAN 100, with a layer 2 class of service of 3 for control traffic, and a layer 2 class of service of 7 for data traffic. portcfg fciptunnel 8/ge0 create 2 192.168.10.1 192.168.20.1 0 -v 100 -p 3 -P 7 Fabric OS 6.2 administrator guide 479
