portCfg 636 -b | --min-comm-rate value -B | --max-comm-rate value 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. For Brocade FX8-24, the valid range is 10,000 Kbps to 1,000,000 Kbps for 1G ports and 10,000 Kbps to 10,000,000 Kbps for 10G ports. For Brocade 7840, the valid range is 20,000 Kbps to 10,000,000 Kbps. The maximum committed rate can be no larger than five times the minimum committed rate. In the previous releases, the maximum and minimum rates had to be configured to the same value for circuits using the XGE ports on the FX8-24 blade. You can configure different values for minimum and maximum rates for each circuit of a tunnel using the XGE ports. 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 [disable | enable] Disables or enables the FCIP FastWrite on the specified extension tunnel. -t | --tape-pipelining [disable | enable | write-only] Configures Open Systems Tape Pipelining on the specified extension tunnel. By default, OSTP is disabled . When using this operand with fciptunnel create, specify one or more of the following operands: -t | --tape-pipelining Enables write-read Tape Pipelining (FCIP FastWrite must also be enabled.) -N | --no-read-pipelining Disables tape read-pipelining. This operand is valid only with fciptunnel create and -t must be specified enabling the feature. The combination of -t and -N effectively enables tape write-pipelining. This operand is supported on the Brocade FX8-24 blade only. When using this operand with fciptunnel modify, specify one or more of the following: -t | --tape-pipelining mode Modifies the Open System Tape Pipelining configuration. Specify one of the following modes: disable Disables Tape Pipelining enable Enables write-read Tape Pipelining (FCIP FastWrite must also be enabled). write-only Enables write-only Tape Pipelining (FCIP FastWrite must also be enabled).
