Configuring ports
5
When the wizard prompts you to select allowed port types, if all of these boxes are selected, there
are no constraints on port type. The port will negotiate to its preferred type when the switch comes
up, depending on what type of device or switch it is connected to.
Clearing a check box guarantees that the port will not attempt to function as a port of the
unchecked type. At least one type must remain selected. L-Port and F-Port cannot both be cleared.
NOTE
To configure a port as an EX_Port, the switch must be capable of supporting FCR/FCIP features. The
EX_Port option is disabled in the wizard if the switch does not meet these requirements.
Long distance mode
Port long distance configuration can be performed here and in the Switch Admin Extended Fabric
tab. For information about long distance mode settings, see Chapter 13, “Administering Extended
Fabrics.
FC Fastwrite
FC Fastwrite reduces the number of round-trip times required to write data.
For Brocade 48000 and 7500 switches, you can enable FC Fastwrite. When FC Fastwrite is
enabled, all GigE port and FCIP features are disabled.
CONFIGURING FCIP PORTS
With the FC Port Configuration wizard, you can configure the port type for logical FCIP ports.
Configure the port to be a VE_Port if you want to merge with the remote fabric with which you are
communicating. Configure the port to be a VEX_Port if you want to communicate with a remote
fabric without merging with it.
Admin Domain considerations: You can configure FCIP ports only when the current Admin Domain
owns the switch.
The following procedure describes how to open the FC Port Configuration wizard. The wizard is
self-explanatory, so the explicit steps are not documented here.
To configure FCIP ports
1. Click a port in the Switch View to open the Port Administration window.
2. Click the FC Ports tab.
3. From the tree on the left, select the logical port you want to configure.
4. Click the General subtab.
5. Click the Edit Configuration button.
The FC Port Configuration wizard opens. The fields are populated with the current
configuration values.
6. Follow the steps in the wizard.
For VEX_Ports, you will need to specify the Fabric ID. You can choose any unique fabric ID as
long as it is consistent for all VEX_Ports that connect to the same edge fabric.
