Performing Advanced Configuration Tasks TABLE 9 Duplicate PWWN behavior: Second login overrides first login (continued) Input port First port login is F_Port First port login is NPIV port If Base Device Logout is enabled on the NPIV port, only the base device is logged out and the remaining NPIV devices stay logged in. Setting 2, Mixed precedence When setting 2 is selected, the precedence depends on the port type of the first login: ∙ If the previous port is an F_Port, the first login takes precedence. ∙ If the previous port is an NPIV port, the second login overrides the first login. TABLE 10 Duplicate PWWN behavior: Port type determines which login takes precedence Input port First port login is NPIV port First port login is F_Port FLOGI received New login forces an explicit logout of original FDISC on the previous NPIV port. New login is rejected and the new port is persistently disabled. If Base Device Logout is enabled on the NPIV port, only the base device is logged out and the remaining NPIV devices stay logged in. FDISC received New FDISC forces an explicit logout of original FDISC on the previous NPIV port. New FDISC is rejected. If Base Device Logout is enabled on the NPIV port, only the base device is logged out and the remaining NPIV devices stay logged in. Setting the behavior for handling duplicate PWWNs You can configure how duplicate port WWNs (PWWNs) are handled if a device attempts to log in with the same PWWN as another device on the switch. 1. Connect to the switch and log in using an account with admin permissions. 2. Enter the switchDisable command to disable the switch. 3. Enter the configure command. 4. Enter y after the F_Port login parameters prompt. F-Port login parameters (yes, y, no, n): [no] y 5. Enter one of the following options at the Enforce FLOGI/FDISC login prompt to select the behavior for handling duplicate PWWNs. ∙ Enter 0 to have the first login take precedence over the second login (default). ∙ Enter 1 to have the second login override the first login. ∙ Enter 2 to have the port type determine the behavior. If a duplicate login is received on an F_Port, the duplicate login is rejected and the old login is preserved; if a duplicate login is received on an NPIV port, the newer login is accepted. Enforce FLOGI/FDISC login: (0..2) [0] 1 6. Respond to the remaining prompts, or press Ctrl + D to accept the other settings and exit. Brocade Fabric OS Administration Guide, 8.0.1 102 53-1004111-02
