Modify and delete command options Command options are available that allow you to modify or delete configured elements. NOTE: Using the Modify option disrupts traffic on the specified FCIP tunnel for a brief period of time. Modifying FCIP tunnels 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: lot 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 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. The Ethernet port used by the tunnel (ge0 or Ge1). The tunnel number (0 - 7). The modify option changes the FCIP tunnel configuration options and parameters. New committed traffic rate in Kb/sec on the existing FCIP tunnel. Disables (0)/Enables (1) compression on the existing FCIP tunnel. SACK ON (1)/SACK OFF (0) on the existing FCIP tunnel. Enables (1)/Disables (0) FCIP fastwrite. Enables or disables VC QoS mapping. Enables (1)/Disables (0) tape pipelining on the existing tunnel. If tape pipelining is enabled, you must also enable fastwrite. The new keep-alive timeout on the existing FCIP tunnel. A range of valid values is 8 through 7200 sec. If tape pipelining is enabled, the default and minimum value is 80 sec. The new minimum retransmit time for the existing FCIP tunnel. A range of valid values is 20 through 5000 ms (milliseconds). 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 sec). 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. 402 Configuring and monitoring FCIP extension services
