The switch Ethernet interface

The CP8 blade enables eth0 by default. If an error is encountered on eth0, it is treated the same as

for any other port, unless the error causes the eth0 port to go down. If eth0 goes down, the eth3

interface becomes active and will remain active even if eth0 comes back up. Use one of the

following actions to restore eth0 as the active interface.

• Unplug the network cable, wait 5 seconds, and then plug it back in.

• Perform an HA failover routine.

• Power down the switch and then power it back up again.

ATTENTION

Performing and HA failover and powering down the switch will cause a disruptive delay in content

delivery.

Supported devices

Management Ethernet port bonding is available on a CP8 blade when it is installed on a

Brocade DCX, Brocade DCX-4S, Brocade DCX 8510-8, or Brocade DCX 8510-4.

Setting up the second Ethernet port on a CP8 blade

The port speed and duplex mode between the Ethernet ports should always match. Both ports

should be set at a fixed speed or set to autonegotiate.

1. Make sure that the speed and link operating mode settings are the same for both eth3 and

eth0. Refer to “Setting port modes” on page 93 for instructions on setting port modes, and

“Setting port speeds” on page 94 for instructions on setting port speeds.

2. Physically connect the second Ethernet port to the same network as the primary Ethernet port.

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 58. Otherwise, connect using SSH.

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

2. Enter the ipAddrShow command.
