Configuration scenarios The actual number of virtual N_Port_IDs accepted per port and per switch is determined by the limits you set, and also by the limit that is reached first. For example, if you have set switch.login.perPortMax to 25, and switch.login.perSwitchMax to 100, the first 4 ports will accept up to 25 virtual N_Port_IDs each. However, the fifth port will reject any more virtual N_Port_IDs because the switch.login.perSwitchMax parameter (100) has been reached. If you set switch.login.perPortMax to 50, and switch.login.perSwitchMax to 25, the first port requests 50 virtual N_Port_IDs; 25 are accepted, and 25 are rejected. The second port requests 50 virtual N_Port_IDs, but none are accepted, because the switch.login.perSwitchMax limit of 25 has been reached. Viewing NPIV port configuration information To view the NPIV capability of switch ports, enter the portCfgShow command. 1. Connect to the switch and log in using an account assigned to the admin role. 2. Enter the portCfgShow command to view the switch ports information. Alternatively, you can enter the switchShow command to view the WWN of an N_Port, or Enter the portShow command to view the N_Port attributes. The following example shows whether or not a port is configured for NPIV: switch:admin> portcfgshow Ports of Slot 0 0 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 Speed AN AN AN AN AN AN AN AN AN AN AN AN AN AN AN AN Trunk Port ON ON ON ON ON ON ON ON ON ON ON ON ON ON ON ON Long Distance VC Link Init Locked L_Port Locked G_Port Disabled E_Port ISL R_RDY Mode RSCN Suppressed Persistent Disable NPIV capability ON ON ON ON ON ON ON ON ON ON ON ON ON ON ON ON Use the switchShow and portShow commands to view NPIV information for a given port. If a port is an F_Port, and you enter the switchShow command, the port WWN of the N_Port is returned. For an NPIV F_Port, there are multiple N_Ports, each with a different port WWN. The switchShow command output indicates whether or not a port is an NPIV F_Port, and identifies the number of virtual N_Ports behind it. The following is sample output from the switchShow command: switch: admin> switchshow switchName:swd77 switchType:32.0 switchState: Online switchMode:Native switchRole:Principal switchDomain: 99 switchId:fffc63 switchWwn:10:00:00:05:1e:35:37:40 zoning: OFF switchBeacon:OFF Area Port Media Speed State Fabric OS 6.2 administrator guide 335
