Ports

1. Connect to the switch and log in using an account with admin permissions.
2. Enable the portSwapEnable command to enable the feature.
3. Enter the portDisable command on each of the source and destination ports to be swapped.
switch:admin> portdisable 1
ecp:admin> portdisable 1/2
4. Enter the portSwap command.
switch:admin> portswap 1 2
ecp:admin> portswap 1/1 2/2
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 483.
If ports are persistently disabled and you use the portEnable command to enable a disabled port,
the port will revert to being disabled after a power cycle or a switch reboot. To ensure the port
remains enabled, use the portCfgPersistentEnable command as shown in the following
instructions.
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
Use the following procedure to enable 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 on whether it is
necessary to specify a slot number:
•
To enable a port that is disabled, enter the command portEnable portnumber or
portEnable slotnumber/portnumber . You can also use the -x option to enter the value in
hexadecimal if you prefer. See the Fabric OS Command Reference for more details on this
command.
•
To enable a port that is persistently disabled, enter the command portCfgPersistentEnable
portnumber or portCfgPersistentEnable slotnumber/portnumber.
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.
