Brocade FICON Administrator’s Guide (Supporting Fabric OS v7.3.0) - Manual (Page 62)

FICON CUP license. The Mode Register is accessible via Web Tools and the Fabric OS
commands.
‐ In-band Management is enabled, provided you do not disable FMS mode, disable and
then enable the switch, or power-cycle the switch.
‐ If you disable FMS, a FICON CUP license is required to re-enable the feature.
• Upgrading with FMS mode enabled from Fabric OS v7.2.1 or prior to v7.3.0 or later requires that
the following attributes be configured. If FMS mode is enabled on the switch and these are not
configured, upgrade will fail.
‐ An insistent domain ID (IDID)
‐ A valid SCC_Policy (configured and activated)
‐ A Fabric Wide Consistency Policy => SCC:S (Strict mode)
NOTE
You enable the Fabric Wide Consistency Policy on the fabric once the switch joins the
fabric.
‐ HIF mode enabled.
Port swap limitations
The following limitations apply to swapping ports or blades using CLI commands or Brocade Network
Advisor options. Note that some of these constraints apply to logical switches in general, and are not
necessarily limited to switches enabled for FMS mode.
• A port can be swapped with only one other port at a time.
• Ports cannot be swapped if one of the ports has a value of 0xFE or 0xFF in the Fibre Channel
Port ID (FC ID) field.
• The logical switch addressing mode cannot be changed if the logical switch contains swapped
ports.
• Logical switch configuration (LSCFG) operations cannot operate on swapped ports.
• You cannot swap ports that are in two different logical switches.
• Swapped ports cannot be moved out of a logical switch.
• The portaddress - -bind command is not allowed on swapped ports.
• The wwnaddress - -bind command is not recommended on swapped ports.
Mode register bit settings
A mode register controls the behavior of the switch with respect to CUP itself, and with respect to the
behavior of other management interfaces. The mode register bits are described in the table below.
FICON CUP mode register bits TABLE 7
ACP Alternate control prohibited. Because the Fabric OS CLI, Web Tools, and Brocade Network Advisor are
considered to be switch consoles, this bit has no effect on their operations. Attempts to set CUP
parameters through SNMP are denied when this bit is set on. The default setting is 1 (on).
ASM Active=Saved mode. When this bit is set on, all CUP configuration parameters are persistent, meaning
that they will be saved in nonvolatile storage in the IPL file that is applied upon a cold reboot or a power
cycle. The default setting is 1 (on).
