portCfgLongDistance portCfgLongDistance Configure a port to support long distance links. Synopsis: V3.1.x portCfgLongDistance portnumber[, "distance"] Synopsis: V4.1.x portcfglongdistance [slotnumber/]portnumber [distance_level][vc_translation_link_init] Availability Admin Release V3.1.x and V4.1.x Description V3.1.x Use this command to specify the allocation of enough full size frame buffers on a particular port to support a long distance link of up to 100 km. The port is used as an E_Port. The configuration is saved in the non-volatile memory and is persistent across switch reboot or power cycle. When this command is invoked without the optional operand, you are prompted to enter the long distance level number. The level value must be one of the following: ■ L0: Deconfigure the port to be a regular switch port. This option supports up to 10-km links for 1 Gbps, or 5-km links for 2 Gbps. ■ LE: Level E mode is for E_Ports for distances beyond 5 km and up to 10 km, especially for 2 Gbps link speeds. LE does not require extended fabric license. ■ L1: Level one long distance, up to 50 km. ■ L2: Level two long distance, up to 100 km. When a port is configured to be a long distance port, the output of portShow and switchShow displays the long distance level. In the portShow output, the long distance level is indicated as "medium" for level 1 long distance, and Fabric OS Version 3.1.x/4.1.x Reference Guide 541
