Duplicate PWWN handling during device login If a device attempts to log in with the same PWWN as another device on the switch, you can configure whether the new login or the existing login takes precedence. You can configure how duplicate PWWNs are handled by selecting an option in the Enforce FLOGI/FDISC login prompt of the configure command. • Setting 0: First login takes precedence over second login (default behavior). • Setting 1: Second login overrides first login. • Setting 2: The port type determines whether the first or second login takes precedence. Setting 0, First login precedence When setting 0 is selected, the first login takes precedence over the second. This is the default behavior. Table 8 describes the behavior when setting 0 is selected. TABLE 8 Duplicate PWWN behavior: First login takes precedence over second login Input port First port login is NPIV port First port login is F_Port FLOGI received The new login is rejected and the new port is persistently disabled. FDISC received The new FDISC is rejected. The new login is rejected and the new port is persistently disabled. The new FDISC is rejected. Setting 1, Second login precedence When setting 1 is selected, the second login takes precedence over the first. Table 9 describes the behavior when setting 1 is selected.
