NOTES 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 will be disabled due to a fabric ID oversubscription. If two fabrics have been assigned
the same fabric ID, one of them will be 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.
The 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 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 Virtual Fabric or Admin Domain restrictions that may be in
place. Refer to Chapter 1, "Using Fabric OS Commands" and Appendix A, "Command Availability" for
details.
OPERANDS When invoked without operands, this command displays the usage. The following operands are
supported:
slot
On bladed systems only, specifies the slot number followed by a slash (/).
port
Specifies the port number. Use switchShow for a list of valid ports. When
executed with [slot/]port only, the command displays the current port
configuration.
-a admin
Enables or disables the specified port as an EX_Port. Valid values are 1 (enable
as EX_Port), 2 (disable as EX_Port and enable as non-EX_Port). portCfgDefault
may also be used to disable EX_Ports.
-f fabricid
Specifies the fabric ID. The valid values for FID are from 1 through 128 or the alias
name of the fabric. The alias name is displayed, only if alias name exists for the
corresponding Edge Fabric ID. Execute fcrconfigure --show to view the alias
name configuration.
-r ratov
Specifies the R_A_TOV used for port negotiation. Valid values are 2000 to
120000. This operand is only applicable if the "Fabric Parameter" attribute value is
not "Auto Negotiate".
-e edtov
Specifies the E_D_TOV used for port negotiation. Valid values are 1000 to 60000.
This operand is only applicable if the "Fabric Parameter" attribute value is not
"Auto Negotiate".
-d domainid
Specifies the preferred domain ID. For Brocade native mode (-m 0), valid values
are 1 to 239.
-p pidformat
Specifies the Port ID format. Valid values are 0-native, 1-core, 2-extended edge.
This operand is applicable only when port mode is set to 0 (native mode). If port
mode is not "Brocade Native", the Port ID format displays as "Not applicable".
