Message The command failed due to presence of long-distance ports in LS mode. Please remove these settings before proceeding. Probable Cause and Recommended Action The firmware download operation was attempting to downgrade a system to Fabric OS v5.0.0 or lower with long-distance ports in LS mode. Long-distance ports in LS mode is not supported in firmware v5.0.0 or lower, so the firmware download operation failed. Change the long distance port setting to a supported distance setting using the portCfgLongDistance command (the numerical value representing each distance level is shown in parentheses), and then retry the firmware download operation. The supported settings are described briefly below: L0 (0) Specify L0 to configure the port to be a regular switch port. A total of 20 full-size frame buffers are reserved for data traffic, regardless of the port's operating speed; therefore, the maximum supported link distance is 10 km, 5 km, or 2.5 km for the port at speeds of 1 Gbit/sec, 2 Gbit/sec, or 4 Gbit/sec respectively. L0.5 (4) Specify L0.5 (portCfgShow displays the two-letter code as LM) long distance, up to 25 km. A total of 12, 25, or 50 full-size frame buffers are reserved for data traffic for the port at speeds of 1 Gbit/sec, 2 Gbit/sec, or 4 Gbit/sec respectively. L1 (1) Specify L1 long distance to support a long distance link up to 50 km. A total of 25, 50, or 100 full-size frame buffers are reserved for data traffic for the port at speeds of 1 Gbit/sec, 2 Gbit/sec, or 4 Gbit/sec respectively. L2 (2) Specify L2 long distance to support a long distance link up to 100 km. A total of 50, 100, or 200 full-size frame buffers are reserved for data traffic for the port at speeds of 1 Gbit/sec, 2 Gbit/sec, or 4 Gbit/sec respectively. For previously released switches (Bloom1-based), the number of frames buffers is limited to 63. LE (3) Specify LE mode is for E_Ports for distances beyond 5 Km and up to 10 Km. A total of 5, 10, or 20 full-size frame buffers are reserved for port speeds of 1 Gbit/sec, 2 Gbit/sec, or 4 Gbit/sec, respectively. LE does not require an Extended Fabrics license. LD (5) Specify LD for automatic long-distance configuration. The buffer credits for the given E_Port are automatically configured, based on the actual link distance. Up to a total of 250 full-size frame buffers are reserved, depending upon the distance measured during E_Port initialization. If the desired distance is provided, it is used as the upper limit to the measured distance. For Bloom1-based systems, the number of frame buffers is limited to 63. LS (6) Specify LS mode to configure a long-distance link with a fixed buffer allocation. Up to a total of 250 full-size frame buffers are reserved for data traffic, depending on the desired distance value provided with the portCfgLongDistance command. For Bloom1-based systems, the number of frame buffers is limited to 63. Fabric OS 5.2.x administrator guide 169
