5. Enter the portSwapShow command to verify that the port area IDs have been swapped.
A table shows the physical port numbers and the logical area IDs for any swapped ports.
6. Enter the portSwapDisable command to disable the port swap feature.
Port activation and deactivation
By default, all licensed ports are enabled. You can disable and re-enable them as necessary. Ports
that you activate with the Ports on Demand license must be enabled explicitly, as described in
“Ports on Demand” on page 535.
CAUTION
The fabric will be reconfigured if the port you are enabling or disabling is connected to another
switch.
The switch with a port that has been disabled will be segmented from the fabric and all traffic
flowing between it and the fabric will be lost.
Enabling a port
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the appropriate command based on the current state of the port and whether it is
necessary to specify a slot number:
• To enable a port that is disabled, enter the portEnable [slot/]port command.
• To enable a port that is persistently disabled, enter the portCfgPersistentEnable [slot/]port
command.
If you change port configurations during a switch failover, the ports may become disabled. To
bring the ports online, re-issue the portEnable command after the failover is complete.
Disabling a port
1. Connect to the switch and log in using an account with admin permissions.
2. Enter the appropriate command based on the current state of the port and whether it is
necessary to specify a slot number:
• To disable a port that is enabled, enter the portDisable [slot/]port command.
• To disable a port that is persistently enabled, enter the portCfgPersistentDisable
[slot/]port command.
Port decommissioning
Port decommissioning is an Fabric OS 7.0.0 and later provides an automated mechanism to
remove an E_Port or E_Port trunk port from use. The port decommissioning feature identifies the
target port and communicates the intention to decommission the port to those systems within the
fabric affected by the action. Each affected system can agree or disagree with the action, and
these responses are automatically collected before a port is decommissioned.
