The switch Ethernet interface 2 NOTE When you change the Ethernet interface settings, open connections such as SSH or Telnet may be dropped. Reconnect using the new Ethernet IP address information or change the Ethernet settings using a console session through the serial port to maintain your session during the change. You must connect through the serial port to set the Ethernet IP address if the Ethernet network interface is not configured already. For details, refer to "Connecting to Fabric OS through the serial port" on page 56. Virtual Fabrics and the Ethernet interface On the Brocade DCX and DCX-4S, the single-chassis IP address and subnet mask are assigned to the management Ethernet ports on the front panels of the CPs. These addresses allow access to the chassis-more specifically, the active CP of the chassis-and not individual logical switches. The IP addresses can also be assigned to each CP individually. This allows for direct communication with a CP, including the standby CP. On the Brocade DCX and DCX-4S Backbones, each CP has two management Ethernet ports on its front panel. These two physical ports are bonded together to create a single, logical Ethernet port, and it is the logical Ethernet port to which IP addresses are assigned. IPv4 addresses assigned to individual Virtual Fabrics are assigned to IP over Fibre Channel (IPFC) network interfaces. In Virtual Fabrics environments, a single chassis can be assigned to multiple fabrics, each of which is logically distinct and separate from one another. Each IPFC point of connection to a given chassis needs a separate IPv4 address and prefix to be accessible to a management host. For more information on how to set up these IPFC interfaces to your Virtual Fabric, refer to Chapter 10, "Managing Virtual Fabrics". Displaying the network interface settings If an IP address has not been assigned to the network interface (Ethernet), you must connect to the Fabric OS CLI using a console session on the serial port. For more information, see "Console sessions using the serial port" on page 56. Otherwise, connect using SSH. Use the following procedure to display the network interface settings: 1. Connect to the switch and log in using an account assigned to the admin role. 2. Enter the ipAddrShow command. ipAddrShow Example output for a Brocade Backbone ecp:admin> ipaddrshow SWITCH Ethernet IP Address: 10.1.2.3 Ethernet Subnetmask: 255.255.240.0 CP0 Ethernet IP Address: 10.1.2.3 Ethernet Subnetmask: 255.255.240.0 Host Name: ecp0 Gateway IP Address: 10.1.2.1 CP1 Ethernet IP Address: 10.1.2.4 Ethernet Subnetmask: 255.255.240.0 Fabric OS Administrator's Guide 63 53-1002745-02
