Per-Port NPIV login limit

Adaptive Networking on Access Gateway considerations

QoS is configured in the fabric, as normal, and not on the AG module..

QoS on Access Gateway is only supported on Fabric OS v6.3 and later.

You should disable HBA QoS if connected to a Fabric OS v6.2 AG switch.

Disable QoS on an AG port if it connects with a switch running Fabric OS v6.2. Otherwise, the
port will automatically disable with an error. To recover, disable QoS on the port, and then
enable the port.

Disabling QoS on online N_Ports in the same trunk can cause the slave N_Port ID Virtualization
(NPIV) F_Port on the Edge switch to become persistently disabled with “Area has been
acquired.” This is expected behavior because after QoS is disabled, the slave NPIV F_Port on
the Edge switch also tries to come up as a master. To avoid this issue, simply persistently
enable the slave F_Port on the switch.

QoS takes precedence over ingress rate limiting

Ingress rate limiting is not enforced on trunked ports.

Per-Port NPIV login limit

The Per-Port NPIV login limit feature allows you to set a specific maximum NPIV login limit on
individual ports. This feature works in both Native and Access Gateway modes. Using this feature,
you can use additional tools to design and implement a virtual infrastructure. In Access Gateway
mode, this feature allows smaller login limits for F_Ports and larger limits for N_Ports. Note that
N_Ports are restricted by the NPIV login limit of the connecting port on the Edge switch.

Note the following aspects of this feature:

Upgrading between Fabric OS v6.4.0 and v7.1.0 will retain the NPIV settings.

The value that you set is persistent across reboots and firmware upgrades.

This feature supports virtual switches, so each port can have a specific NPIV login limit value in
each logical switch.

The login limit default is 126. This value will be set for a port when the portCfgDefault
command is used to reset port default values.

Before changing the login limits, you must disable the port.

This feature only applies to ports enabled for NPIV operation. To enable NPIV functionality for a
port, you can use the portCfgNPIVPort --enable command when the switch is in Fabric OS
Native mode. For details, refer to the Fabric OS Command Reference Manual.

Setting the login limit

Use the following procedure to set the NPIV login limit for a port.

1. Connect to the switch and log in using an account assigned to the admin role.

2. Disable the port by entering the portdisable port command.

3. Enter the portcfgnpiv --setloginlimit [Slot/]Port loginlimit command to set the login limit. For

example, the following example sets the login limit on port 12 to 200.

portcfgnpivport --setloginlimit 12 200
