Dell 8/4Gbps FC SAN Module Administrator’s Guide 553-1001345-01Port mapping 2Default port mappingTable 3 shows the default port mapping. By default, Failover and Failback policy are enabled on allexternal ports (N_Ports).The FC SAN Module ships with 12 active ports and two installed SFP+ optical transceivers. A portupgrade license is available to activate 12 additional ports and includes two additional SFP+transceivers. Additional single SFP+ transceivers are also available for maximum bandwidth andredundancy.By default, port licensing on the FC SAN Module is dynamic, so port licenses are flexibly assignedfrom the pool of available licenses. Ports 17 and 18 are licensed at the factory (and align with thetwo included SFP+ transceivers). The remaining ten licenses are assigned to active ports asrequired, making port licensing more flexible.If no additional SFP+ transceivers are used to enable additional external ports on the FC SANModule and your M1000e blade chassis contains more than four blade servers, you should makemodifications to the default port mapping to ensure connectivity for all servers to the SAN.Remapping portsexternYou can modify the default port mapping by adding internal ports (F_Ports) to an external port(N_Port). Doing so, routes that traffic to and from the fabric through the specified external port.You can assign an internal port to only one primary external port at a time. If the internal is alreadyassigned to an external port, you must remove it from the external port before you can add it to adifferent port.Use the following steps to add an internal port (F_Port) to an external port (N_Port).1. Connect to the FC SAN Module and log in using an account assigned to the admin role.2. Enter the command with the --mapadd n_portnumber “f_port1;f_port2;... “operand to add thelist of internal to the external port.The f_portlist can contain multiple internal ports (F_Ports) numbers separated by semicolons,for example “17;18”.switch:admin> ag --mapadd 13 "6;7"F-Port to N-Port mapping has been updated successfullyTABLE 3 FC SAN Module default F_Port-to-N_Port mappingTotal Ports Server Ports(F_Ports)External Ports(N_Ports)Default F_ to N_Port Mapping24 1-16 0, 17-23 1, 2 mapped to 173, 4 mapped to 185, 6 mapped to 197, 8 mapped to 209, 10 mapped to 2111, 12 mapped to 2213, 14 mapped to 2315, 16 mapped to 0
