Brocade Fabric OS Administrators Guide (Supporting Fabric OS v7.3.0) - Manual (Page 75)

The following restrictions apply to port decommissioning:
• The local switch and the remote switch on the other end of the E_Port must both be running Fabric
OS 7.0.0 or later.
• Port decommissioning is not supported on ports with DWDM, CWDM, or TDM.
• Port decommissioning requires that the lossless feature is enabled on both the local switch and the
remote switch.
Use the portDecom command to begin the decommission process.
Setting network interface modes
Network interfaces can be set to use one of three link operating modes: full duplex, half duplex, or
autonegotiate.
Changing the link operating mode is not supported for all network interfaces or for all Ethernet network
interfaces. On the CP blade in a Brocade Backbone, the supported interfaces are eth0 and eth3. On all
other platforms, only eth0 is supported.
For dual-CP systems, the ifModeSet command affects only the CP to which you are currently logged in.
Therefore, to set the link operating mode on the active CP, you must issue the ifModeSet command on
the active CP; and to set the mode on the standby CP, you must issue the ifModeSet command on the
standby CP. During failover, the mode is retained separately for each CP because the physical links
may be set to operate in different modes.
ATTENTION
Forcing the link to an operating mode not supported by the network equipment to which it is attached
may result in an inability to communicate with the system through its Ethernet interface. It is
recommended that the ifModeSet command be used only from the serial console port. When used
through an interface other than the serial console port, the command displays a warning message and
prompts for verification before continuing. This warning is not displayed and you are not prompted when
the command is used through the serial console port.
Use the following procedure to set the mode of a port.
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the ifModeSet command.
Enter y at the prompts to confirm the active link operating mode values. Enter n to deactivate that
mode.
