Fibre Channel Interfaces Chapter 13 Configuring Interfaces Send documentation comments to [email protected] Note To ensure that ports that are part of ISLs do not get changed to port mode F, configure the ports in port mode E, rather than in Auto mode. Note When the command is executed from the command line, switch operation remains graceful. No ports are flapped. To sets the administrative mode of Fibre Channel ports to mode F in the CLI, follow these steps: Step 1 Step 2 Command switch# config t switch(config)# system default switchport mode F switch(config)# no system default switchport mode F Purpose Enters configuration mode. Sets the administrative mode of Fibre Channel ports to mode F (if applicable). Sets the administrative mode of Fibre Channel ports to the default (unless user configured). Note For detailed information about the switch setup utility see Chapter 5, "Initial Configuration." Configuring Port Speeds By default, the port administrative speed for an interface is automatically calculated by the switch. Caution Changing the port administrative speed is a disruptive operation. To configure the port speed of the interface, follow these steps: Step 1 Step 2 Step 3 Command Purpose switch# config t Enters configuration mode. switch(config)# interface fc 1/1 Selects the mgmt0 interface and enters interface configuration mode. switch(config-if)# switchport speed 1000 Configures the port speed of the interface to 1000 Mbps. The number indicates the speed in megabits per second (Mbps). You can set the speed to 1000 (for 1-Gbps interfaces), 2000 (for 2-Gbps interfaces), 4000 (for 4-Gbps interfaces), 8000 (for 8-Gbps interfaces), or auto (default). switch(config-if)# no switchport speed Reverts the factory default (auto) administrative speed of the interface. 13-14 Cisco MDS 9000 Family CLI Configuration Guide OL-18084-01, Cisco MDS NX-OS Release 4.x
