Reference Guide
∙ Default switch behavior is the legacy functionality (base device logout is disabled).
∙ All checks for duplicate WWN remain valid.
∙ The base device logout feature can coexist with other switches that do not have base device logout enabled, even if they are in
the same fabric.
∙ Any port-related Fabric OS features that depend on the base device cannot work when the base device logs out. One example
of this is device probing.
∙ Trunking is not affected by base device logout because only Brocade switches utilize F_Port trunking, and the related Access
Gateway N_Ports do not keep NPIV devices logged in when the base device logs out.
∙ QoS, FEC, and credit recovery features are not affected by base device logout.
∙ Port swap is not affected by the base device logout feature.
∙ Connectivity to NPIV devices is not affected when the base device logs out.
∙ Base device logout is not supported on ICL, VE/GE (E/Ex/LG) ports.
∙ Base device logout must be disabled on all the ports before downgrading from Fabric OS 7.3.0 to an earlier version.
Viewing base device logout setting

The switchshow command displays the number of base devices as "1" and the number of NPIV devices. If the base device is logged out,
the output displays only the number of NPIV devices.
When base device logout is enabled and the base device has logged out, the portshow command output displays a
FLOGI_LOGO
with
other port flags, and the PWWNs of the NPIV devices.
When base device is logged out, the agShow, fdmiShow, and nsShow commands do not list the base device information.
