Portcfgnpivport - Brocade Communications Systems 8 Command Reference Manual

portCfgNPIVPort

Enables or disables N_Port ID virtualization (NPIV) functionality on a port and sets the per-port
login limit.
Synopsis portcfgnpivport --enable [slot/]port
portcfgnpivport --disable [slot/]port
portcfgnpivport --setloginlimit [slot/]port login_limit
portcfgnpivport --help
portcfgnpivport [slot/]port mode
Description Use this command to enable or disable NPIV functionality on a port and to configure the maximum
number of logins for this port. Changes made by this command are persistent across switch
reboots and power cycles.
N_Port ID Virtualization (NPIV) enables a single Fibre Channel protocol port to appear as multiple,
distinct ports, providing separate port identification within the fabric for each operating system
image behind the port as if each operating system image had its own unique physical port. NPIV
assigns a different virtual port ID to each Fibre Channel protocol device without impacting your
existing hardware implementation. The virtual port has the same properties as an N_Port and is
therefore capable of registering with all fabric services.
The following conditions must be met for a switch port to respond to NPIV requests from an NPIV
device:
NPIV capable:
NPIV enabled:
NPIV HA:
Use the --setloginlimit option to configure the number of permitted logins per NPIV port. Up to
255 virtual port IDs are allocated per NPIV port, which means each NPIV port can support up to
255 logins. The number of logins you can configure per port is between 0 to 255. The default is
126 per port. The sum of all configured per-port login maximum values cannot exceed the total
number of logins set for the switch with the configure command.
As of Fabric OS v.6.4.0 you can no longer use the configure command to set the NPIV port login
limit on a per-switch basis. However, the maximum number of logins per switch is still set and
enforced by the configure command. Use configure to display the current setting.
Note The execution of this command is subject to Virtual Fabric or Admin Domain restrictions that may
be in place. Refer to chapter 1, "Using Fabric OS commands" and Appendix A, "Command
Availability" for details.

NPIV capability is a switch blade or port attribute that is required for NPIV
functionality. Some blades within a switch, or some ports within a switch or
blade, may not have NPIV capability. NPIV functionality cannot be enabled on
such ports and they do not respond to NPIV requests.
NPIV functionality must be enabled on a port for it to respond to NPIV
requests. NPIV is enabled by default. It can be selectively disabled or
re-enabled on specified switch ports using this command.
To enable NPIV functionality on dual-CP systems, NPIV-enabled firmware
must be running on both the active and the standby CPs. This requirement
does not apply to single-CP systems.
