2 portCfg default circuit. The default circuit created with the tunnel is automatically assigned the circuit ID 0. You can modify the default circuit with the fciptunnel modify command. To add additional circuits to an existing tunnel, use the fcipcircuit create command. modify [tunnel_arguments] [circuit_arguments] Modifies the properties of an existing FCIP tunnel. To modify a tunnel, you must specify at least one of the tunnel or circuit parameters for the command to be effective. Any circuit attribute you change with the fciptunnel modify command affects only the FCIP circuit 0. All other circuits remain unchanged. To modify a circuit other than circuit 0, you must use the fcipcircuit modify command. In order to create a default circuit 0 with the tunnel, you must at least specify the following circuit arguments with fciptunnel create: remote_ip_address Specifies the IP address for the remote end of the FCIP circuit. local_ip_address Specifies the IP address for the local end of the FCIP circuit. The following two operands are exclusive; you can either specify a committed rate or a minimum and maximum rate for circuit 0. You can modify these parameters later with fciptunnel modify. comm_rate Specifies the committed traffic rate on the FCIP tunnel in Kbps. The valid range is 10000 Kbps to 1000000 Kbps. There is no default. Both sides of the circuit must have matching configurations. -b |--min-comm-rate value, -B |--max-comm-rate value Alternately you may set a minimum and a maximum for the committed rate to configure the tunnel for Adaptive Rate Limiting (ARL), which allows for a more effective sharing of bandwidth between applications. The valid range is 10000 Kbps to 1000000 Kbps. The maximum committed rate can be no larger than five times the minimum committed rate, and both sides of the circuit must have matching configurations. Optional tunnel_arguments for fciptunnel create and modify include the following. Tunnel parameters are by default disabled. To change the default (for example, enabling FastWrite) with fciptunnel create, specify the parameter only. To modify any of these parameters with fciptunnel modify, specify the parameter and one of the values in square brackets. -f |--fastwrite [0|1] Disables (0) or enables (1) FCIP FastWrite on the specified FCIP tunnel. -t |--tape-pipelining [0-2] Configures Open Systems Tape Pipelining on the specified FCIP tunnel. By default, OSTP is disabled (0). When using this operand with fciptunnel create, specify one or more of the following: -t |--tape-pipelining Enables write-read Tape Pipelining (FCIP FastWrite must also be enabled.) 620 Fabric OS Command Reference 53-1001764-02
