2. Issue the portCfg fcipTunnel command to modify FCIP tunnels (you must specify at least one characteristic to modify). The command syntax is as follows: portcfg fciptunnel [slot/]ge[port] modify tunnel_id [-b comm_rate] [-c 0|1] [-s 0|1] [-f 0|1] [-k timeout] [-m time] [-q control_dscp] [-Q data_dscp] [-p control_L2Cos] [-P data_L2Cos} [-r retransmissions] [-t 0|1] where: slot ge0|ge1 tunnel_id modify -b comm_rate -c 0|1 -s 0|1 -f 0|1 -M 0|1 -t 0|1 -k timeout -m time -r retransmissions -q control_dscp -Q data_dscp -p control_L2Cos -P data_L2Cos is the number of a slot in a 4/256 SAN Director or DC Director chassis that contains an FR4-18i blade. This parameter does not apply to the stand-alone 400 Multi-protocol Router. is the Ethernet port used by the tunnel (ge0 or Ge1). is the tunnel number (0 - 7). changes the FCIP tunnel configuration options and parameters. is the new committed traffic rate in Kb/sec on the existing FCIP tunnel. disables (0) or enables (1) compression on the existing FCIP tunnel. disables (0) or enables (1) selective acknowledgement (SACK) on the existing FCIP tunnel. enables (1) or disables (0) FCIP fastwrite. disables (0) or enables (1) VC QoS mapping. disables (0) or enables (1) tape pipelining on the existing tunnel. If tape pipelining is enabled, you must also enable fastwrite. is the new keep-alive timeout on the existing FCIP tunnel. A range of valid values is 8 through 7200 seconds. If tape pipelining is enabled, the default and minimum value is 80 seconds. is the new minimum retransmit time for the existing FCIP tunnel. A range of valid values is 20 through 5000 ms. The maximum number of retransmissions on the existing FCIP tunnel. A 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 the tunnel does not time out before the host times out (about 80 seconds). If you change this value, the value specified must be greater than the calculated value. 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. 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. Specifies the PL2_Class_of_Service/Priority, as defined by IEEE 802.1p for the FCIP control connection. The range is 0-7; the default is 0. Specifies the PL2_Class_of_Service/Priority, as defined by IEEE 802.1p for the FCIP data connection. The range is 0-7; the default is 0. 410 Configuring and monitoring FCIP extension services
