Reference Guide
The CP 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
ev
en 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 a High Availability (HA) failover routine.
∙ Power down the switch and then power it back up again.
ATTENTION
Performing an HA failover and powering down the switch will cause a disruptive delay in content delivery.
Supported Brocade Backbones and Directors
Management Ethernet port bonding is available on the following CP blades.
∙ CP8 blade installed on a Brocade DCX 8510 Backbone
∙ CPX6 blade installed on a Brocade X6 Director
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 the Ethernet
interface mode and speed on page 56 for instructions on setting port modes, and Setting port speeds on page 83 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
NOTE
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 38. Otherwise,
connect using SSH.
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter ipAddrShow.
ipAddrShow
The following example shows the output of ipAddrShow for a Brocade Backbone:
ecp:admin> ipaddrshow
