Allowed Port Types; Long Distance Mode - Brocade Communications Systems StoreFabric SN6500B Administrator's Manual

Allowed port types

For FC ports, the Port Admin tab displays the following values relating to port type:
Port Type
Allowed Port Type
The allowed port types indicate any constraints on what types the port can be configured when it
comes online. For normal (that is, non-EX-Port) ports, the following are the allowed port types:
L_Port
F_Port
E_Port
U_Port
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 negotiated to its preferred type when the switch comes
up, depending on what type of device or switch to which it is connected.
Clearing a check box guarantees that the port does not attempt to function as a port of the
unchecked type. At least one type must remain selected. An FC port cannot be configured as an
E_Port and L_Port.
L_Ports are not supported on the Brocade FC16-32, Brocade FC16-48, Brocade FC8-32E, Brocade
FC8-48E, Brocade 6505, Brocade 6510, and Brocade 6520.
NOTE
To configure a port as an EX-Port, the switch must be capable of supporting FCR or 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 configurations can be performed in the Switch Admin Extended Fabric tab if the
link is used over long distances. To configure the long-distance settings, the EGM license must be
enabled on the switch. Otherwise, access to this feature is denied and an error message displays.
For information about long-distance mode settings, refer to
Fabrics".
The EGM license is required only for 8 Gbps platforms, such as the following:

NOTE
If you configure a disabled port as an EX-Port, the wizard displays the Enable Port after
configuration check box. If you select the check box, the disabled port is automatically enabled
after configuration; otherwise, the port remains in the same state after configuration.
This is the actual or current port type. If the port is offline, this value is the
allowed types (or U_Port, if no type constraint is specified). If the port is
online, this value is the type to which the port has been configured.
The allowed or configured port type.
The port can be used to connect a loop device.
The port can be used to connect a non-loop device.
The port can be used to connect to another switch. On the Brocade FC8-64,
ports 56 through 63 are not available as E_Ports. This option is unavailable
for these ports.
For a physical FC port: the port can be any one of E_Port, F_Port, or L_Port.
For a logical FC port: the port can be either VE_Port or VEX-Port.
