Configuring EX_Ports on an ICL
The following restrictions apply when configuring EX_Ports on an ICL:
∙ Both the active and standby CP must be running Fabric OS 7.2.0 or later in the case of DCX 8510 Backbone.
∙ EX_Port on ICL is supported in DCX 8510 Backbones and X6 Directors when all the port blades in the chassis belong to one of
these blade types: FC16-32, FC16-48, FC16-64, FC32-48.
NOTE
Device discovery will not occur properly with ICL EX_Port connected edge fabrics if the FC router has unsupported
blades that are not mentioned in the previous restriction.
∙ Switches must have Virtual Fabrics enabled.
∙ EX_Ports on ICLs are allowed only on the base switch. F_Ports are not supported in the base switch.
∙ You must be in Brocade native mode.
∙ You cannot configure a VEX_Port on an ICL .
∙ The ICLs must be in a symmetric topology. For more information on topologies, refer to the chapter on Inter-Chassis Links
(ICLs).
∙ Bladeless configuration (where the chassis has core blades but no application blades) is not supported.
To configure EX_Ports on an ICL, perform the following steps:
1. Configure an 8-bit zero-based Dynamic Area mode or a 10-bit Dynamic Area mode on the FC router to bring up ICL
EX_Ports.
Configure...
Enable a 256 Area Limit
(0 = No,
1 = Zero Based Area Assignment,
2 = Port Based Area Assignment): (0..2) [0]
The following options are available:
∙ 0: 10-bit Dynamic Area Mode. ICL EX_Ports, F_Ports, and regular EX_Ports have 8-bit areas.
∙ 1: 8-bit Dynamic Area Mode. ICL_EX ports have 8-bit areas.
∙ 2: Not permitted if ICL ports are present in the logical switch.
2. On the FC router, disable all QSFP ports by issuing the portDisable command.
switch:admin> portdisable 6/20-23
You can verify that all ports have been disabled by issuing the portShow command for the ports.
3. Configure EX_Ports on the ICL by issuing the portCfgEXPort command. If you configure EX_Port on one of the QSFP ports,
the configuration is automatically propagated to the other 3 QSFP ports.
The following example configures EX_Port on one of the QSFP ports.
switch:admin> portcfgexport 6/20 -a 1 -f 45

FCR port to FCR port.
