Persistently enabling and disabling ports for CUP
When FMS mode is enabled, you cannot use the portCfgPersistentEnable and
portCfgPersistentDisable commands to persistently enable and disable ports. Instead, use the
following procedure.
1. Connect to the switch and log in using an account assigned to the admin role.
2. Enter the ficonCupShow modereg command to display the mode register bit settings.
3. Verify that the ASM bit is set on (1).
4. If the ASM bit is set off (0), enter the ficonCupSet modereg asm 1 command to set the bit to on.
For more information on this command and an example of command output, refer to the Fabric
OS Command Reference.
5. Use the portEnable and portDisable commands to enable and disable ports as necessary.
The ports remain enabled or disabled after a switch reboot.
switch:admin> portenable 1/1
Refer to Disabling and enabling ports - persistent states on page 46 for more information on enabling
and disabling ports and persistent states.
