portCfgEXPort
Sets a port to be an EX_Port, and sets and displays EX_Port configuration parameters.
Synopsis portcfgexport [slotnumber/]portnumber [-a admin][-f fabricid][-r ratov][-e edtov][-d domainid]
[-p pidformat][-t fabric_parameter][-m port mode]
Description Use this command to configure a port as an EX_Port.
This command also displays and changes a port’s EX_Port configuration. If no optional operands
are given, this command displays the currently configured values; otherwise, it sets the specified
attributes to the new values. The port must be disabled (for example, using portDisable) prior to
setting EX_Port attributes. The port must be enabled (using portEnable) before the port can
become active following EX_Port parameter changes.
IPFC over FCR allows the routing of IPFC traffic between different EX-Ports in the case where
EX-Ports are connected to an edge fabric that has IPFC capable devices. IPFC traffic is routed
between EX and VEX Ports. IPFC traffic can be related to the same edge fabric or to different edge
fabrics.
When the port is not active, the preferred domain ID is configurable. This is the domain ID that is
used by the EX_Port’s front phantom domain to request a domain ID from the principal switch. The
domain ID received becomes the subsequent preferred domain ID which is persistent and
displayed.
The fabric ID must be the same for every router port connected to the same edge fabric, and
different for every edge fabric. If two ports are connected to the same fabric but have been
assigned different fabric IDs, one of them is disabled due to a fabric ID oversubscription. If two
fabrics have been assigned the same fabric ID, one of them is disabled due to a fabric ID conflict.
When a port is changed from FL_Port to EX_Port, the topology is implicitly changed to
point-to-point.
Front domain WWN field displays the WWN of the front domain. If the port is enabled and the state
is “OK”, the edge fabric principal switch’s domain ID and WWN also are displayed.
If the Fabric Parameter value is “Auto Negotiate”, the port ID format, R_A_TOV, and E_D_TOV values
display the negotiated values indicated by “(N)” next to them. The negotiated values are what the
edge switch specifies in the ELP request. If the state is “Not OK”, the R_A_TOV and E_D_TOV
display “Not Applicable”. By default, all EX_Ports are auto-ELP enabled.
If the Fabric Parameter attribute value is “User configured”, the port ID format R_A_TOV and
E_D_TOV values display the configured values.
The execution of this command is subject to Admin Domain restrictions that may be in place.
Operands This command has the following operands:
-a admin Specify whether to enable or disable this port as an EX_Port. Valid values are
1 (enable as EX_Port), 2 (disable as EX_Port, in other words, enable as
non-EX_Port). portCfgDefault can also be used to disable EX_Ports.
-f fabricid Specify the fabric ID. Valid values are 1-128.
-r ratov Specify the R_A_TOV used for port negotiation. Valid values are 2000 -
120000. This operand is only applicable if the "Fabric Parameter" attribute
value is not "Auto Negotiate".
