Duplicate PWWN handling during device login
If a device attempts to log in with the same port WWN (PWWN) as another device on the same switch, you can configure whether the
new login or the existing login takes precedence.
Note that if a device attempts to log in with the same PWWN as another device on a different switch, both devices are logged out. This
section describes what happens with devices logging in on the same switch.
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. The following table 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.
The new login is rejected and the new port is
persistently disabled.
FDISC received The new FDISC is rejected. The new FDISC is rejected.
Setting 1, Second login precedence
When setting 1 is selected, the second login takes precedence over the first. The following table describes the behavior when setting 1 is
selected.
TABLE 9 Duplicate PWWN behavior: Second login overrides first login
Input port First port login is F_Port First port login is NPIV port
FLOGI received New login forces an explicit logout of original
login on the previous F_Port.
The previous F_Port is persistently disabled.
New login forces an explicit logout of original
FDISC on the previous 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.
FDISC received New FDISC forces an explicit logout of original
login on the previous F_Port.
The previous F_Port is persistently disabled.
New FDISC forces an explicit logout of original
FDISC on the previous NPIV port.
