Configuring The Max Npiv Limit; Configuring The System Default F Port Mode - Cisco MDS 9000 Series Configuration Manual

Configuring the MAX NPIV Limit

• TL ports and SD ports cannot be configured automatically. They must be administratively configured.
Note
• You cannot configure Fibre Channel interfaces on Storage Services Modules (SSM) in auto mode.
Configuring the MAX NPIV Limit
Note
Both the max-npiv-limit and trunk-max-npiv-limit can be configured on a port or port channel. If the port
or port channel becomes a trunking port, trunk-max-npiv-limit is used for limit checks.
To configure the maximum NPIV limit, perform these steps:
Step 1
Enter configuration mode:
switch# configure terminal
Step 2
Select a Fibre Channel interface and enter interface configuration submode:
switch(config)# interface fc 3/29
Step 3 Configure switch port mode F on the Fibre Channel interface:
switch(config-if)# switchport mode F
Step 4
Specify the maximum login value for this port:
switch(config-if)# switchport max-npiv-limit 100
The valid range is from 1 to 256.

Configuring the System Default F Port Mode

The system default switchport mode F command sets the administrative mode of all Fibre Channel ports to
mode F, while avoiding traffic disruption caused by the formation of unwanted ISLs. This command is part
of the setup utility that runs during bootup after a write erase or reload command is issued. It can also be
executed from the command line in configuration mode. This command changes the configuration of the
following ports to administrative mode F:
• All ports that are down and that are not out of service.
• All F ports that are up, whose operational mode is F, and whose administrative mode is not F.
The system default switchport mode F command does not affect the configuration of the following ports:
• All user-configured ports, even if they are down.
• All non-F ports that are up. However, if non-F ports are down, this command changes the administrative
